What type of reaction occurs when lead nitrate is heated?
Answer and explanation
Correct answer: Thermal decomposition reaction
When lead nitrate is heated, it decomposes into lead oxide, nitrogen dioxide, and oxygen: \(2\mathrm{Pb(NO_3)_2} \xrightarrow{\Delta} 2\mathrm{PbO} + 4\mathrm{NO_2} + \mathrm{O_2}\). The breakdown of one compound into two or more simpler substances by heat is called a thermal decomposition reaction. In a combination reaction, two or more reactants form one product, whereas here one reactant produces several products.
