In this video, we learn how to properly balance chemical equations. You will see what substances are in each side of the equation. You will then need to count the atoms that are on each side of the chemical equation. Once you write down the number of atoms on each side, you will need to even them out. To do this, you need to change the coefficients within the equation. These change the total number of atoms inside of a chemical. Once you do this, you will add more to each atom present and the...

In this video we learn how to balance chemical equations properly. What is a chemical equation? It's a statement that uses a chemical formula to show identities and relative amounts of the substances involved in a chemical reaction. To balance an equation out you must have the same number of atoms on both sides of the chemical equation. Or, you must have the same amount of mass or matter on both of the sides. Once you have these balanced out so they are the same then you will have it complete...

This video shows you how to calculate the percentage yield in chemistry. To find the percentage yield, you will need to divide the actual yield by the theoretical yield. Then, multiply it by 100: i.e. % yield = actual yield/theoretical yield x 100. An actual yield is the amount of a substance produced in an actual laboratory experiment. It is based on an actual physical measurement of a quantity. The theoretical yield is the yield as is calculated on paper: i.e. through calculations. Therefor...
The way to convert 0.300 Moles of water into Grams is to start by writing what you have. Then put grams on top and moles on the bottom, then put one by the mole, the omler mass goes by grams. Now you figure out the moler mass of water which has 2 H and 1 O, its 2 times 1 which is the atomic mass for hydrogen plus 16.0 for oxygen which gives a total of 18.0 g/mol. So then you insert the 18 up by the grams, now you can cancel out the moles and multiply 0.300 times 18.0g and it gives you 5.40 g,...

Oil workers complained of a gooey substance referred to as "rod wax" which kept getting into the machinery and slowing them down. Chesebrough noticed that oil workers also smeared this same substance on their burn marks or dry skin to help speed the healing process.
