Answer 1

Answer:

Substance X is calcium chloride it is used in whitewashing. its formulae is Caco^3

Answer 2

Raman uses solution of a substance X for white washing his house. The substance X is Calcium Oxide(CaO)

Explanation:

Calcium Oxide is mixed with water to form it a solution.

Reaction invloved =>

CaO(s) + H₂O(l) => Ca(OH)₂(aq)

Extra Information:

Calcium Oxide(Ca) =>

1. CaO is also known as quicklime or burnt lime.

2. It is white in colour and alkaline in nature.

3. At room temperature it is a crystalline solid.

4. CaO is prepared by thermal decomposition of limestone or seashells which constitutes of Calcium Carbonate(CaCO₃).

5. CaCO₃ is heated at high temperature of 825°C or above and this process is called calcination or lime burning.

6. Reaction involved for formation of CaO =>

CaCO₃(s) ===> CaO(s) + CO₂(g)

CO₂ leaves CaCO₃ to give CaO.
