1. What does the Law of conservation of mass state? a. According to the Law of Conservation, what is true about the masses of the reactants and the products in a chemical reaction?
b. Find the missing mass in the reactions below:

MgO + H2O → Mg(OH)2
12.4 g ? 21.8

According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants. The law of conservation of mass is useful for a number of calculations and can be used to solve for unknown masses, such the amount of gas consumed or produced during a reaction.
