  1. What you’ll be given • Basic PT with masses and numbers • Gas constant • That’s it…it’s a little light on the ‘complicated’ math. You should definitely knowpv=nrt, density, %comp, atoms molegrams, calorimetry (q=…),

  2. Important Vocab • Avogadros number • effective nuclear charge • Electron Affinity • Electron screening • group 1 aka: • group 16 aka: • group 17 aka: • group 18 aka: • group 2 aka: • Heat of formation • heat of reaction • heisenbergs uncertainty principle • Ionization energy • lattice energy • orbital • specific heat • Weak/strong acids • Work

  3. Practice Problem • What are the trends on the PT for: • Ionization Energy: • Electronegativity: • Atomic Radius: • And WHY are there those trends

  4. At 20oc, what volume would 16 grams of N2take up (1atm)? • What is its density at that temperature?

  5. Copper+ Silver Nitrate → Ag + Cu(NO3)2 • Convert names formula • Balance it • Give the net ionic equation • If 234.5 grams of copper reacted, how many grams of Cu(NO3)2would be produced • How many nitrate ions are there? • How many atoms of copper is that? • %of Silver in Silver Nitrate
