Types of Chemical Reactions
All chemical reactions can be placed into one of the five categories.
All chemical reactions can be placed into one of the five categories.
1) Combustion: A combustion reaction is when oxygen combines
with another compound (usually a hydrocarbon, which is composed
of a combination of carbon and hydrogen) to form water and carbon
dioxide. These reactions are exothermic, meaning they produce
heat. This reaction can be expressed as:

heat. This reaction can be expressed as:
CxHy + O2 → CO2 + H2O
CxHy + O2 → CO2 + H2O
2) Synthesis or Combination: A synthesis (or combination
reaction) is when two or more simple compounds/elements
combine to form a larger compound. These reactions come in the
general form of:
2) Synthesis or Combination: A synthesis (or combination
reaction) is when two or more simple compounds/elements
combine to form a larger compound. These reactions come in the
general form of:
A + B → AB
A + B → AB
3) Decomposition: A decomposition reaction is the opposite of a
synthesis reaction – a larger molecule breaks down to make simpler
ones. These reactions come in the general form:

AB → A + B
AB → A + B
4) Single Replacement: This is when one element trades places
with another element in a compound. These reactions come in the
general form of:
A + BC → AC + B
5) Double Replacement: This is when the metals and nonmetals
of two different molecules switch places, forming two entirely
different compounds. These reactions are in the general form:
AB + XY → AY + BX
