synthesis

2 elements combine to form 1 compound

\
A + X = AX

decomposition

a compound breaks apart into its elements

\
AX = A + X

single replacement

an element combines with a compound to form another compound and an element

\
AX + B = BX + A

AX + Y = AY + X

double replacement

2 compounds combine to form 2 new compounds

\
AX +BY = AY + BX

combuston

a hydrocarbon combines with oxygen to produce carbon dioxide and water

\
Fuel + 02 = H2O + CO2
