Types of Solution in Chemistry

Types of Solution in ChemistryKnowing the different types of solution in chemistry can be a helpful tool for students. There are several different types of solution in chemistry that may make you look at your work in a different light. Keep reading to learn about the different types of solution in chemistry.The first type of solution in chemistry is called a reactant. Reactions in chemistry are one way for molecules to combine and form compounds. The individual molecules react with each other to form compounds or products. In other words, a chemical reaction occurs when two or more components form a new compound.Chemical reactants have an important role in chemistry. A certain amount of reactants can be found in any reaction. However, it's important to know the difference between a reaction and a chemical reaction. A chemical reaction takes place while the chemical component is already in motion. A reaction will continue until the component's motion stops or the temperature of the en vironment changes.A solution is the product of a chemical reaction. When two or more elements combine to form compounds, the process of a chemical reaction begins. A solution is the mass of product that results from a chemical reaction. While a chemical reaction takes place in a solution, a solution doesn't.Another type of solution in chemistry is called a solvent. Solvents are liquids that provide a higher conductivity than water. Liquids have a lower density than water, so solvents can move more than water. Liquids have a greater surface area than water, no solvents are effective at penetrating into a solid's pores. In chemistry, this refers to determining the viscosity of a solution.You might not be familiar with the term solvents. A solvent is a liquid that is applied to a solid. The solvents can dissolve materials and cause them to be soluble. A solid can be dissolved by applying a solvent to it. A typical example of a solute in chemistry is the port that contains yeast.In addi tion to these two types of solution in chemistry, there are others. The four types of solutions in chemistry are known as the group of atoms, the system of atoms, the volume, and the unit of measure. An atom is the smallest component of an element. The other four types of solution in chemistry are based on the structure of the elements themselves.

How to Write the Perfect Science Essay

How to Write the Perfect Science Essay If you are submitting a science paper or an science essay, your approach to the paper and presentation matter a lot. Science papers require a lot of detailed research. Your paper should reflect how well youve researched the topic at hand. It would do well to go through a lot of references quote them, get help from online science tutors when you are stuck or simply to clarify doubts and present your analysis and critique in a structured manner. Here’s a brief guide to what you can do to get top grades with your science essay. For an essay you will be expected to read extensively about the topic, select the best references and then carefully write critical analysis. Your essay should introduce the topic, discuss it and reach a logical conclusion. The essay should have a title page, introduction, body with appropriate section headings, list of conclusions and references. For example: Title Page + ID Description. Displays your name and The student ID number Describes what the essay is about. Occasionally a title can be provided by your college lecturer. Introduction Places the question in its scientific context Gives the minimum required background for the subject Explains logic or proposition Determines the interpretation of the subject Defines important technical terms Do you intend to approach this topic. Body Different classes provides the appropriate section title. Explains logical development of content that tells you which direction you took. Use the relevant information to support the argument.   Use the figures and tables to support text reference to all sources of information including tables and figures numbers and labels used all tables and figures.

13 Famous Singers With Surprisingly Bad Vocal Habits

13 Famous Singers With Surprisingly Bad Vocal Habits Sign up successful Régine, on the other hand, has trouble hitting accurate pitches in general and tends to go sharp (higher than she intended). Listen to her last note in the song for a good example. How to Avoid Pitchy Singing Like any other skill, learning to match pitch requires practice. If you have a lot of trouble singing in tune, devote five to 10  minutes a day to practicing this. I have my students use Pitch Analyzer  and a keyboard to do this. Just open the app, play a pitch on the keyboard, and try to match it with your voice. Pitch Analyzer helps you figure out if you are flat, sharp, or just right. Nasal Singing Rebecca Black Miley Cyrus Humans can breathe (and therefore sing) through both the nose and the mouth. The soft palate, located on the roof of the mouth behind the hard palate, lifts and lowers to block off the nasal passages from the rest of the breathing apparatus. Singing with a lowered soft palate lets air out through the nose, causing a nasally tone. See this video from Miley Cyrus as an example. How to Avoid Nasal Singing Learn to lift your soft palate. If you have ever “plugged” your nose without touching it (when changing a diaper or jumping into a pool, for instance), you already know how to do this. If not, try making a really nasally sound, then doing the exact opposite. If your soft palate is all the way up, you will not sound any different if you plug your nose with your fingers. Throat Tension Katy Perry Christina Aguilera  (last note especially, at 1:53) Throat tension is not only damaging, it sounds more like yelling than singing. In these videos of Katy and Christina, the vocals often sound closer to yelling than to singing. Note the frayed, pressed tone and the lack of vibrato. If you watch closely, you will also notice that you can see both women’s necks visibly straining. How to Avoid Throat Tension There are two ways to decrease throat tension in singers. First and foremost, try to relax your throat. Work in front of a mirror or place your hand around your neck so you can feel your throat muscles better. You can also move your neck around while you sing (from side to side, as though you are shaking your head “no”) to keep it from stiffening. The second way to decrease throat tension is to focus on the fundamentals of singing. Singers throats usually tense up to compensate for a lack of proper technique. Make sure your breath support is working, your soft palate is up, your posture is relaxed, and your energy levels are high as you sing. Tongue Tension Eddie Vedder (Pearl Jam) Sarah Brightman Your tongue is a huge muscle that stretches from the front of your mouth all the way back and down, where it connects to the muscles under your jaw. If any part of the tongue becomes rigid during singing, a distinct, clogged sound emerges. The best example of this that I can think of actually isn’t a singer; it’s Kermit the Frog. If you tense your tongue and talk, you’ll find that you sound like the little green guy. For  singers, this clogged sound results in modified vowels, as well as a general distinct tone quality. Both Sarah Brightman and Eddie Vedder’s sounds are characterized by this sound. Singing with tongue tension causes vocal fatigue and can eventually lead to vocal problems, so it’s not something you should ignore. How to Avoid Tongue Tension Many people are completely incapable of consciously relaxing their tongues, even when they aren’t making sound. Start by resting your tongue on your bottom lip, so you can see it well in a mirror, and relaxing it (a relaxed tongue is fat and motionless). Once you accomplish that, put your tongue back in your mouth and learn how to sing vowels without tensing your tongue. (The mirror is your best friend.) When progressing to words, focus on moving your tongue without making it unnecessarily rigid. Jaw Tension Eddie Redmayne Kathleen Battle When singing, the jaw should be loose and free. Tensing the jaw not only makes it harder to sing, it also sounds (and looks) weird. Eddie Redmayne’s clenched, shaking jaw and matching vocals attest to this. Although Kathleen Battle (an acclaimed classical singer) still sounds lovely, it is obvious from watching her sing that her jaw is doing some bizarre and unnecessary work. How to Avoid Jaw Tension Avoid jaw tension by paying attention. Stretch it out before you sing, look in the mirror, and put your hands on your jaw to feel the muscles. If you notice yourself clenching, stop singing, stretch it out, and try again. Always make sure that you are breathing, standing, and resonating well. Just like the throat, the jaw tends to clench when your singing technique is incomplete. Damaged Vocal Chords Mariah Carey Kelly Clarkson Vocal cord abuse and overuse can damage your vocal cords. Singers who perform lots of taxing music often suffer from vocal cord damage, especially after years of performing in tours and concerts. Kelly still sounds good, but the newly acquired raspy quality and her avoidance of high notes are both red flags. In Mariah’s recording, her cloudy tone quality, squeaking, and inability to hold out notes all point to severely swollen vocal cords. Singers can even get calluses (nodes), polyps, or vocal hemorrhaging (bleeding welts) that require surgery. Adele, Sam Smith, Tove Lo, Keith Urban, John Mayer… the list of celebrity victims goes on and on. How to Avoid Damaged Vocal Chords Be kind to your voice! Don’t scream and yell, and don’t overuse your vocal cords. If you suspect that you have hurt your chords already, or if you don’t know how to sing or speak properly for your health, consult  a voice teacher or a vocal therapist immediately. If it hurts to sing or speak, consider taking a few days off and going on vocal rest (no talking or singing whatsoever). It’s amazing what good a few days of quiet can do. While celebrities sing off-key through their noses, you can learn to sing in tune, with a raised soft palate and healthy vocal cords. Find a good teacher, ask him or her about these vocal faults, and practice a little every day. Soon, you might be singing better than some of your favorite famous singers! Post Author:  Elaina R.

Equivalent Decimals

Equivalent Decimals We can say decimals are a kind of fractional numbers. For example, the decimal 0.5 represents the fraction 5/10. We know 5/10 is equivalent to 1/2. In other words we can say decimal number is a number which contains decimal point. It has whole part and decimal part. We can say digits before decimal as whole part and the digits after decimal as decimal part. We have some rules to write the equivalent decimals. Those are, an equivalent decimal has same digits after the decimal point. If we add a number zero at the end of decimal digits the value of that number will not change. If we add zeros before the whole number the value of the number will not change. And the important thing is the place value of a decimal will not change. Example 1: check the decimal 0.45 is equivalent to 00.4500 Solution: Given decimal is 0.45 We need to find the place values of these two decimals First we can find the place values of 0.45 4 is tenth place and 5 is at hundredth place .(1) Now we can find the place values of the digits of 00.4500 The place value of 4 is tenths and place value of 5 is hundredth ..(2) From (1) and (2), The place values of the digits are same. So the given decimals are equivalent. Example 2: check the decimal 0.5 is equivalent to 00.500 Solution: Given decimal is 0.5 We need to find the place values of these two decimals First we can find the place values of 0.5 5 is tenth place .(1) Now we can find the place values of the digits of 00.500 The place value of 5 is tenths ..(2) From (1) and (2), The place values of the digits are same. So the given decimals are equivalent.

A Day in the Life at Oregon State University

A Day in the Life at Oregon State University Melissa, who specializes in English tutoring, writing tutoring, and a number of other subjects, shared her college experience below. She earned her bachelors degree in psychology from Oregon State University in 2012. Check out what she had to say: Describe the campus setting and transportation options. Melissa: I did my undergraduate work at Oregon State University in Corvallis, Oregon. The town had around 60,000 people and the school had around 18,000 students. The University was a huge part of the community and public transportation was free for all OSU students. I usually took the city bus or rode my bike around campus. Corvallis is a safe place and OSU has a very nice campus that is both pedestrian and bicycle friendly. How available are the professors, academic advisers, and teaching assistants? Melissa: Overall, I think the professors and advisers make themselves available, but it depends on the department. I had problems when I was taking statistics with TAs not being available and that was really frustrating. I ended up getting a tutor and did really well, but I really needed the extra help. How would you describe the dorm liferooms, dining options, location, socialization opportunities with other students? Melissa: I lived about a mile off campus. The dining halls were really nice and provided many choices for students and staff. They were almost always busy during day and were a great place to meet friends. Which majors/programs are best represented and supported? Melissa: The College of Engineering, Business, Geoscience, and Fish and Wildlife were the big programs at OSU. I started out studying business and psychology. While taking general requirements, I didnt feel like there was a lot of support, but within the departments, professors seemed more invested and did a good job of providing support for students. The College of Business had a lot of tools and resources to support students with computer labs, internships, and scholarships. How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Melissa: At first it was hard for me to make friends and get to know people. Greek life is huge at OSU. I was a member of Phi Theta Kappa and Sigma Kappa Delta at my previous school and I didnt pledge once I got to OSU. There were a lot of big events, game day activities, and things to do on the quad and at the Memorial Union, but I was really busy with work and school so I wasnt able to fully participate. Over time, I made friends with people who I had classes with a lot and through study groups, which was really nice. How helpful is the Career Centerand other student support services? Melissa: The Career Center was always holding big events and recruiting opportunities, but the student support I found most helpful was through the library. The library was open 24 hours a day, and had so many student services including scanning books into digital files, access to online articles, and study rooms. How are the various study areas such aslibraries, the student union, and dorm lounges? Melissa: There are so many places to study on campus at OSU! The Valley Library is huge! The coffee shop in the basement was one of my favorite places to study. I also liked the MU. The buildings are all huge and even though they are busy, they provide enough seating to accommodate a lot of students comfortably. Describe the surrounding town. Melissa: Downtown is a short distance from campus and is a popular destination for students, especially on weekends. There are small shops, coffee shops, restaurants, parks, and a river. Just outside of town, there are great places to go hiking like Marys Peak, Bald Hill, and Peavy Arboretum. How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Melissa: The student body was big with around 18,000 students. The popular required classes like math and statistics were really big and had between 100 and 150 students per section and those professors usually taught several sections and had several hundred students. In those classes it was impossible to get help from the professors. The upper division classes usually had between 25 and 50. I liked the small classes a lot better. Most of my classes were smaller and I was pleased with the size. Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Melissa: My favorite class at OSU was Geo 300. The professor (Dr. Cook) was one of the most informed people Ive ever met and his lectures were awesome. Although the class was on resource management, he touched on every element of life including personal enrichment, history, politics, business, and ecology. Every year he took a group of students to Albania to work in a village, where he had a library and he would personally fund a scholarship for one student from that village who excelled. He encouraged me and inspired me through his teaching. He was an amazing person and an excellent teacher. Check out Melissas tutoring profile.

5 Horrible Solo Albums From Famous Musicians

5 Horrible Solo Albums From Famous Musicians Mac Going solo isnt easy.  Once you leave a famous band, its hard to achieve  the same level of success on your own. In this article, Jessica Kane from SoundStageDirect  discusses  five solo albums from famous musicians that just  didnt cut it There are unknown reasons as to why some famous musicians feel the need to try to wing it on their own. Some have found great success upon breaking away from their band, while others have only put more nails in their creative coffins. Ready to hear what many consider some of the worst albums by solo artists? Here are five horrible solo albums from famous musicians: 1) Gone Troppo by George Harrison The Beatles are perhaps the most famous rock band of all time. Paul McCartney, John Lennon, George Harrison, and Ringo Starr have all had successful and well-received solo albums in their post-Beatles lives. However, Gone Troppo by Harrison is one of the weakest releases of the bunch. To say that George Harrison is full of talent is a massive understatement, but his charm, skill, and focus fell short with this album. Its generally regarded as underwhelming and does not capture the magic that Harrison has brought to other albums. Listen to the title track and hear a part of George you havent  heard before: 2) Two Sides of the Moon by Keith Moon Keith Moon is known as one of the most iconic and powerful drummers in rock history. His thunderous hammering can be heard across all of The Whos powerhouse albums of the 1960s and 1970s. Two Sides of the Moon delivers you on a half hour journey to a much too dark side of Moon that is best left unexplored. The tracks on this album are as lifeless as the actual moon. Keith Moon, while a savage drummer, is a pitiful solo artist. He lacks the talent of most famous singers, and despite an impressive lineup that includes Joe Walsh, Ringo Starr, and a rumored David Bowie,  Two Sides of the Moon plays more like a strung-out mishap. This is what happens when you let someone as wild as Keith Moon alone to his own devices inside of a recording studio, with the intention to do a vocal cover album. 3) This Time by Melanie C The Spice Girls treated the world to energetic, fun, and sexy pop music that bred a cult of millions of Spice wannabes and fashion-deficit followers. Sporty Spice, or Melanie C, tried to capture some of that same success in a post-Spice Girl world but fell flat  on her face. While not one of the worst albums of the last 100 years, This Time is just unoriginal and dull. This was Melanies fourth solo effort and one of her weakest. In contrast, Northern Star was a solid pop experience that had good energy and lasting themes. Let your bleeding ears check it out here: 4) Who I Am by Nick Jonas This album deserves to be ranked among the worst albums of all time on every list of bad albums, ever. The Jonas Brothers are known for their cute pop rock that caters to pre-pubescent teen girls. Nick Jonas tried to set himself apart with this edgy attempt at a solo album. The blues is universal, as everyone feels suffering and angst, but Jonas needs to keep out of the blues world. This track is all the reason to stop listening to Nick Jonas: 5) Oh Yes I Can by David Crosby David Crosby is perhaps best known for his influential work with the supergroup Crosby, Stills, Nash, Young, but as a solo artist, hes been hit and miss. Oh Yes I Can is a definite miss. Released in 1989, this album does not bring the listener the same deep emotional satisfaction that was found in previous releases. Crosby is an excellent songwriter and performer, but he should have kept this one to himself. The impact he found in other hits is missing from this release. Conclusion Youve just experienced five horrible solo albums  back to back. Hopefully your ears are recovering now! If you want to avoid making horrible solo albums yourself, schedule a lesson with a private music instructor and get better at your craft today! Know any other horrible albums from famous musicians?
