Give two examples of thermal decomposition.

Explanation

(1) At high temperature , caluium carbonate oxide and carbon dioxide.
`CaCO_(3_((s)))overset("heat")rarrCaO_((s))+CO_(2_((g)))`
At high temperature sugar decomposes into black mass of carbon and water vapour.
`underset("sugar")(C_(12)H_(22)O_(11_((s))))overset("heat"Delta)rarr12C_((s))+11H_(2)O_((g))uarr`
