CHEM 1030 FINAL EXAM FINAL STUDY GUIDE
2026 PRACTICE QUESTIONS ANSWERS
◉ Theoretical Yield. Answer: The maximum amount of product that
can be produced from a given amount of limiting reactant
◉ Percent Yield. Answer: (actual yield/theoretical yield) x 100
◉ Solutions. Answer: Homogeneous mixtures of 2 or more
substances
◉ Solvent. Answer: The major component in a solution
◉ Solute. Answer: The minor component in a solution
◉ Unsaturated Solution. Answer: Contains less dissolved solute for a
given temperature and pressure than a saturated solution; has
further capacity to hold more solute
◉ Saturated Solution. Answer: A solution that contains the
maximum amount of dissolved solute
,◉ Supersaturated Solution. Answer: Contains more dissolved solute
than a saturated solution at the same temperature
(Generally unstable)
◉ Solubility. Answer: 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. Answer: Amount of solute (in moles) divided by volume
of solution
◉ Molarity formula. Answer: moles of solute/liters of solution
◉ Aqueous Solution. Answer: Solution in which water is the solvent
◉ Dilution Equation. Answer: M1V1=M2V2
◉ Electrolytes. Answer: Substance that dissolves in water to yield a
solution that conducts electricity
, ◉ Nonelectrolytes. Answer: Molecular substance that dissolves in
water to yield a solution that does not conduct electricity
◉ Strong Electrolyte. Answer: Dissociates/ionizes completely
◉ Weak Electrolyte. Answer: Dissociates/ionizes partially
Reaction can go back and forth
◉ Acids. Answer: Acid: substance that ionizes in water to produce
H+ions (Arrhenius definition)
Acid: Proton (H+) donors (Brønsted-Lowry)
◉ Strong Acid. Answer: An acid that ionizes completely in aqueous
solution
◉ Weak Acid. Answer: An acid that ionizes partially in aqueous
solution
◉ List of strong acids. Answer: HCl-Hydrochloric acid
HBr-Hydrobromic acid
HI-Hydroiodic acid
HNO3-Nitric acid
