No. Water is H2O. It doesn't have carbon and hence will never form carbon dioxide.
Sucrose
Yes, sucrose is the reactant.
carbon dioxide, when carbonates are heated carbon dioxide is is given off.
the metal carbonate decomposes into a metal oxide and carbon dioxide
It decomposes into calcium oxide and carbon dioxide
Yes, sucrose is the reactant.
Ammonium carbonate when heated decomposes into ammonia, carbon dioxide, and water vapor.
When sodium carbonate is heated, it decomposes into sodium oxide and carbon dioxide. The word equation for this reaction is: Sodium carbonate → Sodium oxide + Carbon dioxide.
It decomposes into calcium oxide and carbon dioxide...
Because it decomposes to form carbon dioxide and barium oxide.
It decomposes into calcium oxide and carbon dioxide...
carbon dioxide [CuCO3 --> CuO + CO2]
