Question

What type of reactions break substances apart into at least 2 products?

Answer 1

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 :)
