Answer:

Decomposition reactions are the separation of a chemical compound into elements or simpler compounds.

Explanation:

Decomposition reactions are the separation of a chemical compound into elements or simpler compounds. It is the opposite reaction of synthesis.

The general formula is #AB->A+B#

E.g. Product of elements:
#2 NaCl-> 2 Na + Cl_"2"#
#2 H_"2"O -> 2 H_"2" + O_"2"#
#2 Li_"2"O -> 4 Li + O_"2"#

E.g. Product of compound(s) (and element):
#2 H_"2"O_"2" -> 2 H_"2"O + O_"2"#
#H_"2"SO_"3" -> H_"2"O + SO_"2"#
#CaCO_"3" -> CaO + CO_"2"#

Hope this helps :)
