Question

Write a chemical equation for solid cadmium hydrogen carbonate decomposes to yield solid cadmium carbonate, water and carbon dioxide gas

Answer 1

The chemical equation for solid cadmium hydrogen carbonate i.e. Cd(HCO3)2 to show  decomposition to yield solid cadmium carbonate i.e. CdCO3, water i.e. H2O and carbon dioxide gas  i.e. CO2  is shown below:

Cd(HCO3)2 = CdCO3 + H2O + CO2
 or Cadmium Bicarbonate yields cadmium carbonate
