Chemical Reactions

Multiple compounds on the left side of the chemical equation and a single compound on the right side.

Two or more substances combine to form another substance.

Examples:

A+B→AB

C + O2 → CO2

A single compound on the left side of the chemical equation, which breaks down (decomposes) into multiple compounds on the right side. (opposite synthesis reaction)

E

xamples:

AB→A+B

2H2O2 → O2 + 2H2O

A single element and a compound on both the left and right sides of a chemical equation

;

Examples:

A +BC → AC + B

Zn + CuCl2 → ZnCl2 + Cu

Two compounds on both the left and right sides of a chemical equation;

Example:

AB + CD --> AD + CB

Oxygen will always be one of the reactants (left side) and water and carbon dioxide will always be products (right side);

E

xamples:

(hydrocarbon + O2 ---> CO2 + H2O )

CH4 + 2O2 → 2H2O + CO2

The process by which the atoms of one or more substances are rearranged to form different substances.
