Question

CaCO3(s) → CaO(s) + CO2(g) Identify the type of reaction.

1) electrolytic decomposition
2) thermal decomposition
3) photolysis
4) displacement reaction​

Answer 1

Answer:

Explanation:

Decomposition: A substance breaks down to smaller species. [e.g. CaCO3(s) → CaO(s) + CO2(g) Decomposition of limestone to calcium oxide (quicklime) and carbon dioxide on heating.]

Answer 2

IT IS A FORM OF THERMAL DECOMPOSITION REACTION .

IN THIS REACTION ,AS WHEN HEATED IS PROVIDED TO COMPOUND OF THE CALCIUM CARBONATE, IT DECOMPOSES IN TO IT'S CONSTITUENT PARTS WHICH ARE CALCIUM OXIDE IN IT'S SOLID FORM ,AND LIBERATION OF CARBON DIOXIDE GAS TAKES PLACE .
