Types of Chemical Reactions

Chem H

synthesis

two substances combine to from a single compound

decomposition

a single compound breaks down into two or more simpler substances

Single replacement

one element takes the place of another element in a compound

Double replacement 

two ionic compounds exchange partners

Combustion

a substance rapidly combines with oxygen to form one or more oxides (always needs oxygen)

Complete combustion or hydrocarbons

the complete combustion (adequate amount of oxygen) of hydrocarbons forms carbon dioxide and water vapor

incomplete combustion or hydrocarbons

the incomplete combustion (inadequate amount of oxygen) of hydrocarbons forms carbon monoxide and water vapor

H₂O + CO₂ → H₂CO₃

Synthesis

KClO₃ → 2KCl + 3O₂

decomposition

Na + HOH → NAOH + ½ H₂

Single replacement

AgNO₃ + NaCl → AgCl + NaNO₃

Double Replacement

2Mg + O₂ → 2MgO

Combustion

C₆H₆ + O₂ → CO₂ + H₂O

Complete Combustion

C₆H₆ + 2.5O₂ → 2CO + 3H₂O

Incomplete Combustion
