Following the Law of Conservation of Mass, predict the minimum amount of nitrogen that will react with 50.0 grams of hydrogen to produce 92.5 grams of ammonia.

Nitrogen + Hydrogen → Ammonia

Predict the amount of oxygen gas that will remain after the reaction of 112.6 grams of calcium with 24.0 grams of oxygen.

Which best represents the law of conservation of mass?

a. mass of reactants > mass of products

b. mass of reactants < mass of products

c. mass of reactants = mass of products

d. mass of reactants → mass of products
