**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
