How To: Balance a chemical equation easily
In this video, we learn how to balance a chemical equation. First, take a look at both sides of the equation and figure out how many atoms there are for both. Once you write this out, you will have an idea of how unbalanced it is. Now that you've done this, you need to think about how you can make the equation equal. Look at the first line and then see how many you have to add to one side to make both equal to each other. Then, go to the second line and do the same. When finished, you will ha...
How To: Follow three rules to balance chemical equations
In this video, we learn how to follow three rules to balance chemical equations. The first rule is that you need to start by balancing elements that appear in only one reactant and one product. The second rule is that you need to multiply through by common factors. You must retain equal numbers of atoms of each element on both sides of the equation. The third rule is: if an atom appear in elemental form on one side of the equation, save it for last. Going over the rules of how the balance the...
