Name :
(a) a nitrate of metal which on heating does not give nitrogen dioxide.
(b) a nitrate which on heating leaves no residue behind.
(c) a metal nitrate which on heating is changed into metal oxide.
(d) a metal nitrate which on heating is changed into metal.
(e) a solution which absorbs nitric oxide.
(f) the oxide of nitrogen which turns brown on exposure to air. How is it prepared ?
(a) Sodium nitrate
2NaNO3heat−−→2NaNO2+O2
(b) A nitrate which on heating leaves no residue behind- Ammonium nitrate.
(c) A metal nitrate which on heating is changed into metal oxide- Calcium nitrate
(d) A metal nitrate which on heating is changed into metal- Silver nitrate
(e) A solution which absorbs nitric oxide- Freshly prepared ferrous sulphate
(f) The oxide of nitrogen which turns brown on exposure to air. - NO combines with Oxygen when exposed to air to give NO2 which is brown in colour.
4NH3(g)+5O2(g)⟶4NO(g)+6H2O(l)
2NO+O2⟶2NO2
