Question

3. Name the solid residue obtained during thermal decomposition of the following Substances : i) Calcium nitrate ii)calcium carbonate iii) Ammonium dichromate iv) Mercuric oxide v) Calcium hydroxide

Answer 1

Answer:

Chemical Formula of Calcium Nitrate is CaNO3

Ca²+NO²-+=CaNO3,residue during thermal decomposition is CaNO3+O2(combustion),CaO(white residue+NO2(gas)+O2(gas) will obtain

Chemical Formula of Calcium Carbonate is CaCO3

Ca²+CO3²-=CaCO3,residue during thermal decomposition is CaCO3+O2(combustion),CaO(white residue+CO2(gas)+O2(gas) will obtain.
