Question

In order to illustrate a combination reaction, a teacher took about 8 grams of

calcium oxide in a glass beaker and pour water over it very slowly.

One of the student observed that the solution started boiling even when the

solution was not being heated. Give reason for his observation. Write the chemical

equation involved.​

Answer 1

Answer:

yes

Explanation:

CaCo3 + 2H2O -: Ca(OH)2 +H2O + CO2

Answer 2

Answers are as follows -

• The chemical reaction between calcium oxide and water is exothermic in nature. This means that the reaction releases heat which is the reason for boiling of solution in absence of any heat source.

The chemical equation for mentioned reaction is -

• CaO + H2O --> Ca(OH)2. The product formed is commonly known as slaked lime and chemically known as calcium hydroxide.
