Metal active order table from K to Mg, nitrates heated to generate nitrite and oxygen :(NO  nitrogen dioxide)Ca(NO3)2Ca(NO2)2+ O2↑
Mg to Cu (including Cu and Mg) , nitrates heated to generate metal oxide, nitrogen dioxide and oxygen: 2Cu(NO3)22CuO+4NO2↑+O2↑
H is between Cu and Mg, so HNO3 thermal decomposition generate NO2, O2 and H2O (H oxide): 4HNO34NO2↑+O2↑+2H2O
Cu later of metal  nitrates heated to generate metal elemental, nitrogen dioxide and oxygen: 2AgNO32Ag+2NO2↑+ O2↑
