Question

solve this also no stuff​

Answer 1

Explanation:

1.The white solid is CaCO3 (Calcium Carbonate)

It will break down into calcium oxide and co2, due to thermal reaction.

2. Due to co2 lime water will get milky.

3. 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.]

4. CaCO3 is a compound because CaCO3(s) → CaO(s) + CO2(g)

5. CaCO3------> Cao + CO2

&

Ca(OH) 2(s) + CO 2 (g) → CaCO3 (s) + H2 O(g)
