Question

give balanced equation for thermal decomposition of lead carbonate, lead nitrate, ammonium dichromate, Mercury II oxide, calcium hydroxide.

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

$\boxed{PbCO_3 \overset{\Delta}{\longrightarrow} PbO + CO_2}$

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

$\boxed{Pb(NO_3)_2 \overset{\Delta}{\longrightarrow} PbO + NO_2 + O_2}$

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

$\boxed{(NH_4)_2Cr_2O_7 \overset{\Delta}{\longrightarrow} Cr_2O_3 + N_2+ H_2O }$

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

$\boxed{HgO \overset{\Delta}{\longrightarrow} Hg + O_2}$

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

$\boxed{Ca(OH)_2 \overset{\Delta}{\longrightarrow} CaO + H_2O}$
