Stoichiometry

5. Any reactant that is used up first in a chemical reaction; it determines the amount of product that can be formed in the reaction
6. Equal volumes of gases at the same temperature and pressure contain equal numbers of particles.
10. A formula with the lowest whole-number ratio of elements in a compound
13. Amount of substance
14. The amount of product that could form calculated from a balanced chemical equation; it represents the maximum amount of product that could be formed from a given amount of reactant

1. The volume occupied by 1 mole of a gas at STP (22.4 L)
2. The mass of one mole of a substance
3. Number of representative particles in a mole, 6.02 X 10^23
4. The portion of chemistry involving the calculation of quantities of substances involved in chemical reactions (and numerical relationships in chemical reactions)
7. The amount of product that actually forms when the reaction is carried out in the laboratory
8. The percent by mass of each element in a compound RepresentativeParticle The smallest unit into which a substance can be broken down without a change in composition, usually atoms, molecules, or ions StandardTemperature&Pressure (STP) The conditions under which the volume of a gas is usually measured
9. A reagent present in a quantity that is more than sufficient to react with a limiting reagent; any reactant that remains after the limiting reagent is used up in a chemical reaction
11. A conversion factor derived from the coefficients of a balanced chemical equation interpreted in terms of moles
12. The ratio of the actual yield to the theoretical yield expressed as a percent; a measure of the efficiency of a reaction
