How to Balance Chemical Reactions in Equations - …
When you write an equation for a chemical reaction, the two sides of the equation should balance — you need the same nuer 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 masses of all the products, you see that they’re the same.
