•The Breakdown of a The Breakdown of a larger compoundlarger compound
Example: Example: 2 H2O 2 H2 + 2 H2O 2 H2 + O2O2
I am so over you
Single Replacement- “My Best Single Replacement- “My Best Friends Girlfriend”Friends Girlfriend”Hey Mark, here comes your friend Pierre

•“Free” element must be the more reactive element for a reaction to occur ( Pierre is more suave then Mark)• The further apart 2 elements are on the activity series, the more likely the higher one will replace the lower one in a compound.• Example: 2K + 2HCl 2KCl + H2
Double Replacement- Double Replacement- “Revenge”“Revenge”
Basic Eqn: AX + BY AY + BX
Pierre, Im sick of you
Chloe was my one true love, but Marks girl is looking pretty Hot.
