Chem 111 final

  1. Where is the atomic mass found and what is it made of?
    • Under the chemical symbol
    • # of protons and electrons
  2. Where is the atomic number found and what is it made of?
    • Above the chemical symbol
    • # of protons OR electrons
  3. What is the number associated with -ite?
    3
  4. What is the number associated with -ate?
    4
  5. If a reaction is exothermic and you decrease the temperature, what happens to K?
    K increases, shifts towards the products
  6. How is acidity and basicity determined with oxoacids?
    • The more O ions, the stronger the acid.
    • Less O ions, the weaker the acid and stronger the base
  7. Lattice energy
    The amount of energy required to separate one mole of solid into gas
  8. Mole fraction
    Mole solute/mol solution
  9. Freezing point depression
    Im (molality) * Kf
  10. Boiling point elevation
    Im (molality) * Kb
  11. Osmotic pressure
    I * M (solute) *RT

    Where R= 0.0821
  12. Raoults Law (vapor pressure lowering)
    P (solution)= mole fraction (solute) * Pressure (solvent)
