Edapt Notes Chem 120Balancing Chemical Equations Balanced chemical equations have the same number of each atom on each side of the arrow. This equation is correct: 2 NaBr + CaCl2 → 2 NaCl + CaBr2 Subscripts tell you how many of an atom you have in a chemical formula. Check each chemical reaction to determine the one that does not have the same number of each atom on each side of the chemical reaction. If a chemical equation violates the Law of Conservation of Mass, the atoms will not equal out on both sides. The correct answer is 2 H2 + N2 → 2 NH3. There are four atoms of H on the left, or rea
