Question

Lead nitrate crystals on strong heating decompose to form a Lead mono oxide, Nitrogen dioxide gas, and Oxygen gas. Explain

Answer 1

Decomposition reaction:

1. A decomposition reaction is a type of chemical reaction that produces two or more products from one source.
2. Lead nitrate is a white color inorganic powder with the chemical formula $\mathrm{Pb}{\left({\mathrm{NO}}_3\right)}_2$.
3. When Lead nitrate decomposes, it produces Lead oxide, a yellow-colored oxide of Lead, brown-colored Nitrogen dioxide gas, and colorless Oxygen gas. $\underset{\mathrm{Lead}\mathrm{nitrate}}{2\mathrm{Pb}{\left({\mathrm{NO}}_3\right)}_2}\stackrel{∆}{\left(\mathrm{s}\right)\to }\underset{\mathrm{Lead}\mathrm{oxide}}{2\mathrm{PbO}\left(\mathrm{s}\right)}+\underset{\mathrm{Nitrogen}\mathrm{dioxide}}{4{\mathrm{NO}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Oxygen}\mathrm{gas}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}$
4. As a result, Lead nitrate is used to produce Nitrogen dioxide gas.
