What Is Precipitation In Chemistry?

What Is Precipitation In Chemistry?The term 'precipitation' has a very different meaning from what is taught in a classroom or a textbook. What we refer to as 'rain'snow' is actually air. Precipitation is water vapor condensed from the atmosphere that fills our earth with our ever-changing weather. Most of the water that we see on earth is actually air; so, why would we call it rain?When the air cooled, some water molecules bonded together and formed clouds and rain. This process is how clouds form and rain is formed. The water vapor then freezes to form ice crystals and once the clouds started to form, these tiny ice crystals fell down into the atmosphere and froze. If the temperature were to become lower than freezing, a layer of cool air would collect in the center of the cloud, condense, and fall back to the bottom of the cloud. This was how water vapor became snow.Whenever one chemical reaction occurs, the chemical is said to be 'stirred'. This means that it will begin to combin e with others to form more complex molecules. When chemicals are combined they are able to combine to form more complex molecules which are more stable, more stable than their original state. So, if we take a molecule and react it with another, we can form compounds which we did not have when we first began.Chemicals are the cause of all life, because they carry out all chemical reactions. They bond with each other and break apart to produce energy for life. The breakdown of life is a process of chemistry and life is a chemical reaction.If you watch an apple fall from a tree, the falling apple will make a noise, but if you're watching the cloud that caused the fall, the sound made by the air is the same as the sound of the falling apple. The sound that the air makes is called the sound of a fall. It is this sound that we call falling rain. It is the sound of the raindrops hitting the ground and mixing with the air. When we hear the sound of the fall, we are hearing its meaning; the sound of water condensing into small droplets falling to the ground from a warmer atmosphere.Chemistry occurs when water is combined with a metal such as potassium to form potassium hydroxide. This process is known as an electrolysis reaction. During the electrolysis reaction, water becomes electrically charged; the air particles become electrically static and the potassium hydroxide reacts with the negative electric charge in the air to form sodium hydroxide, which is actually white vinegar.In chemistry, we define the word reaction as an action that results in the same substance being produced a second time, or by doing an action and obtaining a different effect. For example, taking salt and baking soda is an example of a reaction. If you take a pinch of salt and rub the sodium and potassium hydroxide together, you will get a sodium and potassium hydroxide. However, the baking soda will not react with the sodium and potassium hydroxide, therefore you cannot use the sodium and potas sium hydroxide to bake bread.One of the most important concepts in all of chemistry is the fact that an ion is defined as a particle of a single element that has no free electrons, which means there is no free space for an electron to move from its original place to another. In this case, sodium and potassium hydroxide have no free electrons, so they do not interact with each other, so there is no reaction. But when water dissolves into salt, it forms a separate ion, which is sodium hydroxide, so the water molecules will pull electrons away from the sodium hydroxide to form sodium ions, which form a positive ion, which attracts the sodium hydroxide. The same thing happens with potassium, and the water molecules pull electrons away from the potassium ions to form potassium ions, which form a negative ion, attracting the potassium ions.

Fraction multiplication as scaling

Fraction multiplication as scaling Scaling or resizing means comparing the size of the product to the size of one factor on the basis of the size of the other factor, without performing the multiplication. Scaling a number by a fraction less than 1 will be lesser then the original number. Scaling a number by a fraction greater than 1 will be greater than the original number. Multiplication is denoted by a cross sign . Fractions are numbers that can be expressed in the p/q form. Here p the numerator and q is the denominator of the fraction. Example 1: Smiths family ate three fourths of all the cookies in 4 cookie boxes. Write the equation of the quantity they ate and is it lesser than or greater than 4? Solution: Number of cookie boxes = 4. The fraction of cookies eaten from all the boxes = 3/4. The amount to cookies eaten = 4 x 3/4. (This is the equation) Now checking for the multiplication as scaling. We have 4 x 3/4 4 (Because the fraction 3/4 1) Hence the amount eaten by the Smiths family is less than 4 boxes. Question: Multiple choice question (Pick the correct option.) Without multiplying the numbers which one will have the product greater than 2? a) 2 x 5/4 b) 2 x 1/4 c) 2 x 4/4 d) None of these. Correct answer: option a. Explanation: The fraction 5/4 1. Multiplying a number to a fraction greater than 1 will be greater than the given number. Hence 2 x 5/4 2.

Online A Trigonometric Function Tutors

Online A Trigonometric Function Tutors There are 6 basic important trigonometric functions, and they are sine, cosine, tangent, cosecant, secant and cotangent of a given particular angle. Trigonometric functions are very useful because with the help of these functions we can calculate the measure of the sides and the angles of given triangles. These functions are related in many ways and the trigonometric identities and formulas give the relationship between these functions. Using their relationship, we can easily evaluate the angles and sides of a particular triangle. Example 1: Given in first quadrant, tan() = 8/6. What is the value of the trigonometric function cos()? Given tan() = 8/6 In a right angled triangle, to the given angle -tan() = (opposite side)/ (adjacent side) This means the given ratio (opposite side)/ (adjacent side) = 8/6. So let the opposite side = 8x and adjacent side = 6x Then according to Pythagorean theorem, (hypotenuse) = [(8x)2 + (6x)2] = (100x2) This gives the hypotenuse = 10x Since cos() = (adjacent side)/ (hypotenuse)-cos() = 6x/10x. Therefore cos() = 6/10 Example 2: Given in first quadrant,tan() = 3/4. What is the value of the trigonometric function sin()? Given tan() = 3/4 In a right angled triangle, to the given angle -tan() = (opposite side)/ (adjacent side) This means the given ratio (opposite side)/ (adjacent side) = 3/4 So let the opposite side = 3x and adjacent side = 4x Then according to Pythagorean theorem, (hypotenuse) = [(3x)2 + (4x)2] = (25x2) This gives the hypotenuse = 5x Since sin() = ( opposite side)/ (hypotenuse)- sin() = 3x/5x Thereforesin() = 3/5

Ask an Admissions Expert Ralph Becker

Ask an Admissions Expert Ralph Becker Varsity Tutors brings you insider tips and advice straight from nationally recognized admissions experts. Ralph Becker received his Bachelors degree from Yale Universityand his MBA from UCLAs Anderson School of Management. He served as an alumni interviewer on the Yale admissions board and eventually founded Ivy College Prep, a college counseling and preparation service. For many years, Ralph has helped a number of students gain acceptance into top schools such as Brown University, Rice University, Northwestern University, and more. VT: How far ahead of time should a student begin working on his or her college application? Ralph: I like to get students working on the first draft 6-8 weeks before the due date. Often its useful to take a first shot at an essay, and just let it sit for 5-7 days. Starting early allows for such a luxury of time. VT: What are the best ways to go about selecting a terrific essay topic? Ralph: Certainly there are topics best avoided: death of a pet or the big tour of Outer Mongolia are twobut, for the most part, write about what interests you; dont worry about what might, or might not, interest the reader. Trust that your enthusiasm will be reflected on the page. Know your topic thoroughly. If it has to do with cars, know the transmission, alternator, and manifold. VT: Are there any essay topics you get tired of seeing or would warn students to stay away from? Ralph: Ive read dozens of essays about the big game, vying for first seat in the Wind Ensemble, and the difficulties of acculturating into the US from China. You can only imagine what a reader for UCLA (who received over 90,000 applications last year) could say. No matter, if it truly evokes a meaningful emotion in you, and you can get it down on paper, write it up and see what youve got. VT:What is the biggest mistake a student can make on a college application? Ralph: Thinking that he/she can bluff his/her way through the question, What about Northwestern makes you want to apply. Know the school youre applying to well. Realize the admissions people will recognize when you havent done your homework. VT: What is the typical process an admissions officer goes through to evaluate applications? Ralph: Once your application reaches admissions, it goes to your first read. The first read is, oftentimesespecially for Ivy League schools, the colleges regional representative for your high school. Consequently, if a college that youre interested in visits your high school, go to the meeting and introduce yourself to the representative; he or she can greatly influence the success of your application. First reads will give your application a thoughtful review: usually spending between 15-35 minutes with it. Moreover, the first read creates your electronic data sheet, which includes your hard data and basic information. (So if the school super-scores your SAT, the first reader will usually assemble your highest scores from each section of the test.) Interestingly, after the score and GPA are factored out by the first read, its rare the original test scores or transcript will be accessed. The rest of the data is then assembled: race or ethnicity, special status, extracurricularThe fir st read then determines whether your application is admitted or denied, or warranting further discussion. Your application will then workflow to a second reader. If both readers concur on denial or acceptance, then its likely your application will go to the dean of admissions for final authorization. If the two are in disagreement, or your application is somewhere in the gray zonethe purgatory between acceptance and rejection-- then it goes to committee for consideration.VT: What do you think is the single most important thing a student should make sure they present in the best possible way on their application? Ralph: Assuming the application contains essays, within the scope of these essays, the applicant should put forth an image of a knowledgeable, eager, interested candidate who has a decent sense of humor and would be a pleasure to have on campus. If that comes across clearly to the admissions office, the essays have done as good a job as they ever will. VT: How should students go about determining the culture of a university, and whether they would be a good fit? Ralph: Students need to ask themselves some questions: What type of educational methods work best for them? What kind of academic atmosphere best fits their learning style? What college environment do they prefer? Where do they want to live for four years? What kind of social environment is preferred? This list isn't exhaustive, but it's a good place to start. Visiting a campus, sleeping over in a dorm and eating in the cafeteria help a student gain a sense of the school. Trust your gut. VT: Early-action, early-decision, binding/non-binding, regular decisions...With so many choices when applying, what do you recommend to students? Ralph: Applying ED limits your access to financial aid, commits you to a place that you might not like, and surrenders your ability to search and consider many other fine institutions during the admissions process. Under early action (EA), the admitted applicant is free to apply to any other school and has until May 1st to make a final decision. Then there is early action single choice, in which you can only apply early to one school (e.g. Yale), but all the benefits of EA remain. There is also regular, rolling, and open, but, the key issue for most students is to have options. Stick with EA and, unless youre absolutely in love with the college, avoid ED like the flu. VT: How important are grades and standardized test scores when admissions decisions are being made? Ralph: The higher a students grades and test scores, the more options that student will have. The higher both, the more selective schools one might be admitted to, the better the financial package offered, and the better access to a schools honors program. Options make a students life more interesting. VT: What tips do you have for students asking their teachers for letters of recommendation? Ralph: Be very selective about which teachers write your recommendations. Preferably, you can find a teacher from a class in which you participated actively, enjoyed, and, as a consequence, did well. If in the class, you wrote a strong paper, or performed admirably on a test, all the better... Additionally, the teacher should be someone with whom you have a solid rapport. Of utmost importance, make certain that she can write well. It doesnt matter how much a teacher might admire your academic gifts, if she cant express herself well on paper its not going to benefit you. To raise the bar a bit more, its important that the recommender be experienced, preferably with five or more years of classroom experiencemeaning she should already know how to write a decent recommendation and know their import--, and from a class you took in your junior or senior years.

What To Ask During A Phone Interview - Introvert Whisperer

Introvert Whisperer / What To Ask During A Phone Interview - Introvert Whisperer What To Ask During A Phone Interview In order to know what questions to ask in the phone interview, you have to first understand what the purpose of the phone interview is for the hiring business.   Essentially, they have an opening, numerous resumes and they have now identified those resumes that appear to be best qualified for the position.   In order to better understand the candidates and to potentially eliminate any that don’t meet some top level criteria, they use the phone to streamline the process. Usually, the phone interview is to further reduce the pool of potential candidates so it can be a fairly short call with the hiring manager or recruiter asking only a few key questions.   In this bad economy, many hiring managers also use the phone interview as a partial interview in order to save money in flying candidates to the company to interview, if they will fly them in at all.  Usually, the initial call is a screening interview and should they want to do a second call it will be less of a screen than a partial interview.  It’s important to understand the reason for the phone interview in the first place in order for you to be prepared and to set your expectations appropriately.  Some people get off the phone of a phone screen and feel like they were just part of a hit run it went so fast.   As a candidate in the phone screen interview, you want to ensure you know and understand the following basics: Which opening they are referring to â€" you may have applied for several What is the company â€" you may have applied to a “blind” opening or they may be recruiting you making it vital for you to know exactly what company this position is for You may not need to ask those questions if the person you are speaking has freely offered this up to you.   You do want to schedule the phone interview to allow you enough time to prepare when first contacted, even if it is later that same day.  The person calling may really want to push to speak to you then, since they have you on the phone â€" so do your best.   Keep in mind that in a phone interview, they are very likely to be more oriented toward screening you out and may not allow you much time to freely ask questions or sell yourself.  In a typical in-person interview the dialogue is expected to be a bit more evenly split so you can ask them several questions at that time.    If you can inject some key questions you should consider these as your highest priority: What are the important or key elements of this position and what they are looking for in this position â€" This is a good question because it will help you focus your responses on the most important aspects of your skills as it relates to this position.  While you may not be able to fully share that information during a phone interview, you do want to make note of it for the full interview. What created this opening â€" It’s good to understand if a position has been newly formed or if it existed previously.  Positions that are new tend to be somewhat unformed and they may rely on someone who has a history of developing new processes rather than adapting to existing. If you don’t do well with ambiguity of a newly formed position, you may want to ask about their expectations for setting things up and consider pulling yourself out of the running if you’re concerned.  This may also give you an indication of departmental issues if there have been multiple turnovers.   In terms of closing or ending the phone interview you should: Ask about any hesitation or concerns they may have with your qualifications so you can quickly address them before the end of the call Ask about next steps and timing Between those questions and the ones, they need to ask you probably have filled the allocated time.   You always want to be prepared to treat a phone interview the same way you would treat an in-person interview.   Be prepared; be organized and familiar with your resume and the position.   I’d like to share with you more vital Leadership insights and skills on how to plan both Change and Transition no matter what level you are â€" along with all the skills to make you an inspiring Leader.  The new, live interactive program is: “Lead Like You Mean It” Leadership Development Program Click here for more details: https://introvertwhisperer.leadpages.co/leadlikeyoumeanitpilot/ From Dorothy Tannahill-Moran Let me emphasize that Self-Promotion doesn’t have to be obnoxious to be effective.  But, if you don’t Self-Promote you, who will?
