200
This is sometimes used by chemists to speed up a chemical reaction. (not a catalyst)
What is excess reactant
300
True or False In any chemical reaction, the mass of the products is the same as the mass of reactants.
What is TRUE
300

This relates the moles of reactants and products in a chemical reaction

400
This is the maximum amount of product that can be produced from a given amount of reactant.
What is theoretical yield
400

Stoichiometry is the study of what type of relationships among the amounts of reactants used and the amounts of products formed.
