Classifying Chemical Equations

Combustion Reactions

Hydrocarbon+Oxygen (Oxygen on both sides of the equation)

Combination/Synthesis Reactions

any reaction that has only one product (1+1=1)

Decomposition Reactions

any reaction that has only one reactant (1=1+1)

Single-Replacement Reactions

one element goes to another element, elemental forms on both sides ((1+2)+3=(1+3)+2)

Double-Replacement Reaction

2 reacting compounds exchange ions (swap) ((1+2)+(3+4)=(1+4)+(3+2))
