Question

decomposition of metallic nitrates yield respective oxides and
options are
a)nitrogen dioxide
b)sulphur dioxide
c)carbon dioxide
d)hydrogen ​

Answer 1

Answer:

Most metal nitrates decompose on heating to give metal oxides. Decomposition of silver nitrate is different as it yields elemental silver.

2AgNO3⟶2Ag+O2+2NO2

Usually the metals which lie very low in the activity series decompose to give their elemental form. I don't think it's possible to extract metals from just any nitrate by strong heating. They will yield their respective oxide which won't give the element rather they'll just fuse (melt) just like stable metal oxides like Al2O3 does.
