In this video, we learn how to practice balancing chemical equations. First, take a look at the first and second part of the equation. Write out how many atoms each of the elements has in it. Compare each of the sides to see what the difference is between them. Then, find the multiple of each of the elements until they are equal to each other. After you find this, continue to do this for all of the different elements in the equation. This will give you a balanced chemical equation when you ar...

In this video, we learn how to balance an easy chemical equation. You can do your equation by testing it out with the actual chemicals. Watch and see what the reaction is as they start to mix together. To balance this reaction out, you will need to analyze the number of atoms that each element has on both sides of the equation. For it to be balanced, you must have the same number of products and reactants in the equation. You cannot create or destroy matter, you can only change its form, so r...
In this video, we learn how to easily balance chemical equations. There are two sides of a chemical equation, both must be equal to get the proper reaction. To balance these out, first write out the number of atoms that is on each element on each side of the equation. After this, you will need to find the multiple between the matching elements. Once you find this, you will be able to balance out the equation for each of the elements. When you do this, you will have the same mass and atoms on ...
This is a video tutorial in the Education category where you are going to learn how to balance a chemical equation step-by-step.

This is a video tutorial in the Education category where you are going to learn how to understand polyatomic chemical formulas. When writing the formula using polyatomics, the same cross-over rule applies. 1st identify the metal and non-metal. Then you write the symbols, write the charges, cross-over the charges from top to bottom, remove the charge and simplify the numbers and remove the 1s. for example, iron (II) phospahate. The "ate" ending implies that phosphate is polyatomic. The symbol ...

New techniques may improve a swimming pool workout from Masters coach Nancy Kirkpatrick Reno. Before sticking a toe in the water, consider this advice: * Swim in a pool that's at least 20 to 25 yards long; those pools can usually be found at high schools and some gyms. A 50-meter Olympic-size pool is best, but not everyone has access to that. "If you're going to become a lap swimmer," Kirkpatrick-Reno says, "you can't go any shorter or you'll be constantly turning." An outdoor pool is prefera...
