Write the reaction equations for the decomposition of 1) aluminum nitrate 2) zinc nitrate 3) mercury nitrate

The decomposition reaction of aluminum nitrate is as follows:

4 Al (NO3) 3 = 2 Al2O3 + 12 NO2 + 3 O2

Decomposition occurs at a temperature of 150-200 degrees Celsius.

The decomposition reaction of zinc nitrate is as follows:

2 Zn (NO₃) ₂ = 2 ZnO + 4 NO₂ + O₂

Decomposition of zinc nitrate occurs at a temperature.

The decomposition of mercury nitrate occurs under the influence of high temperatures. The chemical reaction looks like this:

Hg (NO3) 2 = Hg + 2 NO2 + O2
