Question

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

Answer 1

Cd(HCO₃)₂ (s) ⇒ CdCO₃ (s) + H₂O (l) + CO₂ (g)

Step-by-step explanation:

Cadmium hydrogen carbonate = Cd(HCO₃)₂ (solid)

Cadmium carbonate = CdCO₃ (solid)

Water = H₂O (liquid)

Carbon dioxide = CO₂ (gas)

Skeleton equation: Cd(HCO₃)₂ (s) ⇒ CdCO₃ (s) + H₂O (l) + CO₂ (g)

This is already balanced.
