How to balance chemical equations File
... When you write an equation for a chemical reaction, the two sides of the equation should balance — you need the same number of each kind of element on both sides. If you carry out a chemical reaction and carefully sum up the masses of all the reactants, and then compare the sum to the sum of the mas ...
