10g of CaCO3 is decomposed, 5.6g of residue is left and 4.4g of CO2 is escapes.
In general ,calcium carbonate decomposes on heating to form calcium oxide and carbon dioxide. Reaction takes place like CaCO3(s)Heat⟶CaO (s)+CO2(g).
Substance breaks down into smaller species is known as decomposition. The Decomposition of limestone to calcium oxide (quicklime) and carbon dioxide on heating. When heated above 840°C, calcium carbonate decomposes, releasing carbon dioxide gas and leaving behind calcium oxide a white solid.
