Answer: yes, when you balance a chemical reaction, you are making sure that the law of conservation of matter is obeyed.

Justification:

1) When you balance a chemical reaction, you add the coefficients to make the number of atoms of each element in the left side of the equation (reactants) equal to number of atoms of the same elements in the right side (products).

2) Since, each atom has a unique atomic mass associated, it results, necessarily, that the mass of the atoms of the reactants is equal to the mass of the atoms of the products.
