Write the equations of the reactions of thermal decomposition of nitrates:

Write the equations of the reactions of thermal decomposition of nitrates: a) sodium b) copper (2) c) silver. Computer electronic balance circuit.

The decomposition of the nitrates of metals occupying different positions in the electrochemical row leads to the formation of different substances, respectively. Nitrite, oxides, clean substances can be formed (if it comes to noble metals). These reactions are redox.

We give the equations of reactions.

2NanO3 = 2NanO2 + O2.
N + 5 + 2e = n + 3    2

2O-2 -4E = O2 (0)    1

2CU (NO3) 2 = 2CUO + 4NO2 + O2.
2O-2 -4E = O2 (0)    1

2n + 5 -e = 2n + 4    2

2AGnO3 = O2 + 2NO2 + 2Ag.
AG + + 1E = AG0    2

N + 5 + 1e = n +    4

2O-2 -4E = 2O0. 1
