1.The actual amount of product that is produced from a given amount of reactant or reactants.  → actual yield  

2.A law which states that in ordinary chemical reactions, the sum of the masses of the reactants always equals the sum of the masses of the products.    → Conservation of Mass

3.The reactant that is not used up in a reaction that goes to completion

→ excess reactant  

4. The reactant that limits how much product is produced in a reaction that goes to completion. It is used up in the reaction. → limiting reactant  

5. The ratio of the actual yield to theoretical yield multiplied times 100.

→ percent yield

6. The maximum calculated amount of product produced from a given reactant in a reaction that goes to completion. → theoretical yield

7. The study of the quantitative relationships between reactants and products in a chemical reaction. → stoichiometry  

Explanation:

1. The actual amount of product that is produced from a given amount of reactant or reactants.  → actual yield  

2. A law which states that in ordinary chemical reactions, the sum of the masses of the reactants always equals the sum of the masses of the products.    → Conservation of Mass

3. The reactant that is not used up in a reaction that goes to completion

→ excess reactant  

4. The reactant that limits how much product is produced in a reaction that goes to completion. It is used up in the reaction. → limiting reactant  

5. The ratio of the actual yield to theoretical yield multiplied times 100.

→ percent yield

6. The maximum calculated amount of product produced from a given

reactant in a reaction that goes to completion.

→ theoretical yield

7. The study of the quantitative relationships between reactants and products in a chemical reaction.

→ Stoichiometry
