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
