i) Zinc Nitrate
ii) Copper Nitrate
iii) Silver Nitrate
Sodium Nitrate​

Answer 1

Answer:

All divalent and trivalent metals (except Hg(NO 3)2) decompose on heating to give metal oxide, nitrogen dioxide and oxygen.

All group 1 metal nitrates (except LiNO3 ) give metal nitrite and oxygen. MNO3 Δ→MNO2 + 12 O2 Therefore, KNO3 Δ→KNO2 + 12 O2 Among monovalent metals ...

Answer 2
