_________ are the starting materials in a chemical reaction.

Factors that affect solubility include:

__________ yield is the amount of product that would occur under perfect conditions.

________ yield is the amount of product actually obtained from a reaction.

The amount of product actually obtained from a reaction is always less than the theoretical yield.

In a reversible reaction, the product cannot change back into the reactants.
