Practice Problems:Here you can
practice problems with us! This differs from the tests and quizzes section because we
actually solve the problem out for you. We'll give you the problem, you solve it, and then
compare it with how we did! This helps YOU learn how to solve problems faster and more
accurately. The Practice Problems are broken down by sections.

Basics
Naming compounds, reading elements from the perioidic table

SI Units/Conversions
Converting between units, and basic SI knowledge
 Significant Figures

Percentage
Percent mass

Gases
Ideal gas law, mole fraction, partial pressures, root mean square velocity, rates of
effusions, simple comparisons

Kinetics
Rate laws, activation energy

Spontaneity
Gibbs Free Energy, Entropy, Enthalpy

Thermochemistry
Heat of formation, standard enthalpies, Hess's Law

Atomic Structure
Wavelength, Quantum Numbers, Shielding

Solutions
Freezing point depression, boiling point elevation, molarity, mass percent, mole fraction,
molality, osmosis
