Why should a chemical equation be balanced?
Question Date: 2014-04-26
Answer 1:

A chemical reaction is written like a math equation: the left side of the equals sign (chemical arrow) should match the right side. A chemical equation helps us understand how much starting chemical reagents we need to produce our desired amount of ending product. Of course, a real reaction might not run to its full extent, but at least we can determine then what factors may help push the reaction along (i.e. more heat?).
