Question

Write one equations each for decomposition reactions where energy is supplied in the form of heat.

Answer 1

Answer and Explanation:

$\huge \text{\boxed{\boxed{\mathbb{THERMAL \ DECOMPOSITION}}}}$

$\diamond$ Thermal decomposition is the splitting of a single reactant to produce 2 or more products in the presence of heat

$\diamond$ Thermal decomposition of lead carbonate yields lead II oxide and carbon dioxide

$\boxed{Pb(CO_3)_2 \rightarrow PbO + CO_2}$

$\diamond$ Thermal decomposition of lead nitrate yields lead oxide, nitrogen dioxide and oxygen

$\boxed{Pb(NO_3)_2 \rightarrow PbO + NO_2 + O_2}$

$\diamond$ Thermal decomposition of ammonium dichromate produces chromium III oxide, nitrogen gas and water vapour

$\boxed{(NH_4)_2Cr_2O_7 \rightarrow Cr_2O_3 + N_2 + H_2O}$

$\diamond$ Thermal decomposition of mercury oxide produces mercury and oxygen

$\boxed{HgO \rightarrow Hg + O_2}$

$\diamond$ Thermal decomposition of calcium hydroxide forms calcium oxide and water vapour

$\boxed{Ca(OH)_2 \rightarrow CaO + H_2O}$
