Balancing Chemical Equations - Chemistry | Socratic
When we balance an equation, we determine the ratio of reactants to products which allows for the total nuer of atoms of reactants to match the nuer of atoms of the products. Since the type of atoms does not change (nuclear processes are a different story) and the nuer of atoms stays that same, the total mass that goes into the chemical change will match the mass that comes out after the
