QUESTIONS AND ANSWERS 100% PASS.
Limiting Reactant - ANS The reactant that limits the amount of product that can form in a
chemical reaction
Theoretical Yield - ANS The maximum amount of product that can be produced from a given
amount of limiting reactant
Percent Yield - ANS (actual yield/theoretical yield) x 100
Solutions - ANS Homogeneous mixtures of 2 or more substances
Solvent - ANS The major component in a solution
Solute - ANS The minor component in a solution
Unsaturated Solution - ANS Contains less dissolved solute for a given temperature and
pressure than a saturated solution; has further capacity to hold more solute
Saturated Solution - ANS A solution that contains the maximum amount of dissolved solute

,Supersaturated Solution - ANS Contains more dissolved solute than a saturated solution at
the same temperature
(Generally unstable)
Solubility - ANS A measure of how much solute can dissolve in a given solvent at a given
temperature.
Soluble: Dissolves in water
Insoluble: Does not dissolve in water
Molarity - ANS Amount of solute (in moles) divided by volume of solution
Molarity formula - ANS moles of solute/liters of solution
Aqueous Solution - ANS Solution in which water is the solvent

Electrolytes - ANS Substance that dissolves in water to yield a solution that conducts
electricity

does not conduct electricity
