Question

The solution of the substance X is Y. The solution of the substance X is used for white washing.
1. Give the name of substance X. Write its formula.
2. Write the reaction of substance X with water. Give its chemical equation.
3. Write the reaction of the substance Y with carbon dioxide and also write its chemical equation

Answer 1

Answer:

Explanation:X is CaCO3

Answer 2

1. The name of substance X is calcium oxide and its chemical formula is CaO.

2. The chemical equation for reaction of substance X with water is $CaO + H_{2}O \rightarrow Ca(OH)_{2}$.

3. Chemical equation for reaction of the substance Y with carbon dioxide  is $Ca(OH)_{2} + 2CO_{2} \rightarrow Ca(HCO_{3})_{2}$.

Explanation:

• Calcium oxide when dissolved in water leads to the formation of a solution of calcium hydroxide. This solution is used for white washing. Chemical formula of calcium oxide is CaO.

• On the other hand, substance formed that is, calcium hydroxide has a chemical formula as $Ca(OH)_{2}$.  And, the reaction equation of this chemical reaction is as follows.

    $CaO + H_{2}O \rightarrow Ca(OH)_{2}$

• This means substance X is CaO and substance Y is $Ca(OH)_{2}$. Now, reaction of substance Y with carbon dioxide is as follows.

        $Ca(OH)_{2} + 2CO_{2} \rightarrow Ca(HCO_{3})_{2}$
