main types synthesis decomposition single displacement double displacement combustion
synthesis
just two substances coming together to form a compound, reactant + reactant ->
single displacement
requires the replacee to havea a lower activity series than the replacer
Double Displacement
double displacement is a reaction of 2 compounds pos and negs switch places to form new stuff only works with ionics
only occurs if one of 3 propduces is formed
- percipitate (s)
- gas (g)
- covalent compound such as water (l)
Combustion
is hydrocarbon react with oxygen to create co2 and h2o
