What Is CO2 in Chemistry?

What Is CO2 in Chemistry?What is CO2 in Chemistry? The definition of CO2 in Chemistry is a gas which contains Carbon and other compounds such as Oxygen. Since the Oxygen and Carbon compounds are heavier than the Hydrogen and Nitrogen molecules, the molecule itself is termed as a heavy molecule.There are several types of gas that are known as the chemical elements. Some of these gases include: nitrogen, oxygen, and methane. However, all of these gases have their own characteristics that make them volatile or not volatile. In other words, some gases react with air by being stored under a vacuum while others form bubbles.Methane is one gas that can be bought and stored under a vacuum. This gas is also called the pale yellow gas.When Methane forms under a vacuum, it becomes a very heavy gas. It is extremely flammable but doesn't have any inherent color. There are several disadvantages associated with this gas.For example, if there is an electrical fire extinguisher near the source of thi s gas, it will not explode due to the fact that the pressure will be equalized to the gas. Also, the vapor itself will have great gravity strength thus making it easy for it to rise into the air.Many other common elements that are found in nature are unstable. As such, the heavier molecules are unable to react with the lighter ones resulting in an extremely low density. When you use a dry chemical fire extinguisher, the moisture in the mixture will tend to combine with the lighter elements to produce the mixtures which you would recognize as water vapor.You must realize that most chemical reactions occur in a gaseous state. If there is an airtight container such as a sealed container, then you don't want the gas to escape but instead hold the gas within the container.

Online Range and Domain Tutors

Online Range and Domain Tutors Domain and range is a very important concept in functions. Domain of a function is all the input values that can be assigned to the functions variable which defines the value of the function. Let y = f(x) be a function. So domain for a function f(x) domain of the function are all the possible input values of X. The range of the function is all the value which are derived using f(x) or all the possible values of y. Example 1: Find the domain of the function f(x) = 3 x/ [(x - 2) (x- 5)? Solution: Given is a function f(x) = 3x/ [(x- 2) (x- 5)]; The domain of the function is all the possible input values of X. First step: Equate the dominator [(x - 2) (x- 3)] = 0 This gives the values x = 2 and x = 3; Hence when x = 2, 3 the function is undefined as denominator = 0; Therefore the domain of the function is: R - {2 ,3} Example 2: Find the domain of the function f(x) = 10 x/ [(x + 6) (x- 12)]? Given is a function f(x) = 10x/ [(x + 6) (x- 12)]; The domain of the function is all the possible input values of X. First step: Equate the dominator [(x + 6) (x- 12)] = 0 This gives the values x = -6 and x = 12; Hence when x = -6, 12 the function is undefined as denominator = 0; Therefore the domain of the function is: R - {-6 ,12}

Dividing Mixed Numbers - Online Tutoring

Dividing Mixed Numbers - Online Tutoring Dividing mixed numbers helps in understanding of dividing mixed fractions. Any fraction that is in the form of whole number and fraction is a mixed fraction. To divide mixed number first convert mixed fractions into improper fractions. Then invert the fraction that is divisor and multiply with the fraction in the numerator. Multiply the numerators together and denominators together. If possible simplify the answer and convert into mixed fraction if needed. The following examples clearly illustrate the steps on dividing mixed numbers. Example 1: Peter is cutting a roll of cookie dough into pieces that is 1 inch thick each. How many pieces can be made if roll is 12 inches long? Solution: Length of roll = 12 Cookie thickness= 1 Divide length of roll by thickness of cookie to find number of cookies to be made. 12 / 1 = (25/2) / (3/2) Put reciprocal of divisor and multiply with the fraction (25/2) / (3/2) = (25/2) * (2/3) = 50 / 6 = 25/3 25/3 is an improper fraction so convert it into mixed number 25/3 = 8 1/3 Therefore, 8 1/3 pieces can be made. Example 2: Felicia can run 18 miles in 1 hours. How many miles per hour can she run? Solution: Total miles she can run = 18 miles Time taken =1 hours Miles she can run in one hour = total miles / time taken Miles in one hour = (18 ) / (1 ) = (37/2) / (5/4) = (37/2) * (4/5) = 148 / 10 Simplify it 148 / 10 = 74/5 = 14 4/5 miles She can run 14 4/5 miles in one hour.

3 Note-Taking Formats Every Student Should Try

3 Note-Taking Formats Every Student Should Try Note-taking is a critical skill that can boost academic success, reduce study time, and ease the process of completing assignments. However, many students are not certain about how to take notes or which style will work best for them. Here are some helpful tips to help you organize your notes. Below are three note-taking formats every student should try when searching for the most effective method. 1. Outline The outline is possibly the most common and familiar form of note-taking for students. The outline format is highly organized; the main topics act as headers, with accompanying details listed under them. With the outline format, pupils often use Roman numerals, an alphanumerical combination, or bullets. This type of note-taking is especially helpful in the scientific disciplines, where information is often intrinsically organized into categories and groups. In addition, this mode of note-taking can function quite well in classes where instructors lecture in a concise manner. Furthermore, the outline tends to be a beneficial way of recording notes when students read textbooks. However, outlines may not be effectual in demonstrating the way ideas are connected or when referencing abstract subjects. You may find this information on how to take notes in a college lectureuseful as well. 2. Web Another system of note-taking that many students find useful is the web. This is sometimes referred to as concept mapping, as well. On a web or concept map, ideas and facts are represented visually. While an outline is linear, a web is graphic. Main points are printed in bubbles, and associated ideas branch off the sides. Lines are customarily drawn between ideas in order to express the relationship between them. One benefit of utilizing the web technique is that it gives you the ability to show how diverse ideas are connected. This method of note-taking is particularly accommodating to those who are visual learners; many students discover that if they add color-coding to their webs, they can express their ideas even more effectively. The web is a wonderful technique to use when you must take notes quickly, or when you need to understand how different concepts are related. However, the web is not as useful for studying, nor is it always the preferred method when you must record numerous details. 3. Cornell method The Cornell method for note-taking is a system that functions remarkably for both taking notes and studying after lecture. To use this technique, you must divide your paper into three sections. First, fold the paper up approximately two inches from the bottom. Then, fold the left side over approximately three inches. When you unfold your paper, you should be able to see three sections. Make use of the spacious right-hand portion to take notes in whichever style works best for you, or use a combination of styles. Record all the detailed information on the right-hand side. On the left-hand side, list the main topics or essential points. Once you have finished taking notes, utilize the bottom section of your paper to create a brief summary of what you have learned from the lecture or reading. The advantage of the Cornell method is that you can juxtapose multiple note-taking formats in one. Additionally, by summarizing at the end of your notes, you force yourself to reflect on the text or lecture in its entirety. Once it is time to study, review for a test, or complete an assignment, both the summary and the left-hand column can assist you. Some students find that they prefer one note-taking format over another. Moreover, some subjects are better suited for one particular form of note-taking. Experiment with these three note-taking formatsto see which one works best for you. If you still cannot decide, consider asking an academic mentor like a tutoror a teacher or a for advice. Doing so could increase your academic success!

Square Root Function Online Tutoring - Maths Tutors

Square Root Function Online Tutoring - Maths Tutors Square root function is a function which is represented with the radical sign . Inside a square root, a number or an expression can be placed and we can find the square root of it. The parent function or the basic square root function is y = x and here y is the function value also known as f(x) and x is the variable. All other square root functions can be derived from this parent function and can be graphed on the X-Y coordinate plane. Example 1: Given the square root function, f(x) = (5x). Find the function value when x is equal to 4. Given square root function: f(x) = (5x) In order to find the function value or the y value at x = 4, we substitute x = 4 in the above square root function. This gives: y = f(4) = (5 * 4) = 20. We can simplify 20 by writing its prime factors== 20 = (2* 2* 5) = 25. Therefore 20 or 25 is the function value at x = 4. Example 2: Given the square root function, f(x) = (x + 6). Find the function value when x is equal to 3. Given square root function: f(x) = (x + 6) In order to find the function value or the y value at x = 3, we substitute x = 3 in the above square root function. This gives: y = f(3) = (3 + 6) = 9. 9 is a perfect square since 9 can be written as 3 * 3. Hence 9 = (3 * 3) = 3 Therefore 3 is the function value when x = 3.

Huntington Learning Center Shares Six Habits of Successful Students

Huntington Learning Center Shares Six Habits of Successful Students As parents, we all want to help our children be as successful in school as they can be. But what is the best way to do so? At Huntington Learning Center, we encounter a range of studentssome who are highly motivated to get into excellent colleges and others who are looking to make improvements in one or more subjects. In the 41 years we have been in business, we have observed that the best students have a lot in commonand they embrace many of the same academic habits. Here are six such habits to keep in mind as you guide your own children toward school success: They commit to study time. When it comes to studying, top-performing students are dedicated. They stick to best practices: choosing to study at a time of day when they are most focused and alert and avoiding distractions during that study window. They are skilled at prioritizing. Highly successful students make the most of study time by prioritizing assignments and tasks before they dive in. At the start of each study session, they review their tasks and rank them from most to least pressing, and only begin working once theyve done so. Time management rules all. The best and brightest are often involved in more than just school. As active young people, these students recognize that theres no room for procrastination when they want to get a lot accomplished. Such students put everything in their planners, from the hours theyre in school to all extracurricular activities, from wakeup time to bedtime. They schedule everything to ensure they make time for all of it. And they are good at using their hours wisely and not losing it to meaningless time-wasters. Organization is a habit. Great students know that a messy backpack or desk leads to lost timeand thats counterproductive. These students develop an organizational system that keeps them on task and minimizes the chances they lose important papers or spin their wheels during study time because they cant locate the supplies they need. They take good notes. An organized approach to note-taking leads to more effective studying later on. Students who become accustomed to taking notes that help them remember important information and key ideas are better equipped for success in college and beyond. They aim to learn, not memorize. Memorization is a requirement sometimes, but excellent students strive to think critically, analyze and evaluate that which they are taught in school. They listen actively in class and strive to process information so they are able to retain it. Parents, the next time you wonder if youre doing all you can to help your children in school, refer to this list. Everything you do to support your children as students should work toward these habits, which together create the gold standard of being a student. As always, Huntington is here to help.
