What you will be able to do
- Report measurements with correct units and significant figures and convert between units
- Use the periodic table and electron configurations to explain atomic structure and periodic trends
- Balance equations and solve mole, limiting reactant, yield and solution concentration problems
- Apply the gas laws and the ideal gas equation to find pressure, volume, temperature and amount
- Calculate heat flow and enthalpy changes using calorimetry, Hess's law and formation data
- Draw Lewis structures and predict molecular shape, polarity and intermolecular forces
- Write equilibrium expressions and solve for concentrations using Q, K and ICE tables
- Calculate pH for strong and weak acids and bases and describe buffers and titrations
Topics
