Chemistry

6 Big Ideas

1. Structure of Matter: Atoms, ions, PNE,
2. Bonding and IMF: S/L/G
3. Chemical Reactions
   1. put them together
   2. take them apart
   3. sub out one for another
   4. two switch partners
   5. ka-boom
   6. heartburn & antacids
4. Kinetics
   1. For a reaction to happen, molecules must collide with sufficient force, and proper orientation
   2. The more that happens, the faster the reactants can be converted into products
5. Equilibrium
   1. Some reactions are reversible, they can go forwards and backwards
   2. When they go forward at the same rate that they go in reverse, they are in equilibrium
      1. Might not have equal amounts R and P, but the RATES F and R are equal
   3. If you poke it, it will move. Action, reaction. LeChat.
6. Thermodynamics
   1. DH, DS, T --Spontaneous? (DG is spontaneous when negative, at equilibrium when zero)
      1. DH is favorable when negative (exothermic), energy leaving, products have less energy than reactants
      2. DS is favorable when positive (more chaotic), greater disruption, more molecules, more positions
   2. neg pos all temps are spontaneous
   3. pos neg no temps are spontaneous
   4. pos pos high temps
   5. neg neg low temps
