Question

which type of reaction occurs when quick lime reacts with water.write down the chemical reaction.​

Answer 1

Answer:

Combination Reaction, Exothermic reaction

Explanation:

Calcium oxide reacts with water to form calcium hydroxide, also called slaked lime.

Here are the equations for this reaction:

Calcium oxide + water → calcium hydroxide

CaO + H2O→ Ca(OH)2

A lot of heat is produced in the reaction, which may even cause the water to boil.Hence it is a combination reaction as well as exothermic reaction.

Answer 2

➪ Exothermic Reaction and Combination Reaction takes place when a quick lime reacts with water.

Chemical Reaction :-

$\sf \red{\: CaO+H_ 2O→Ca(OH)_2}$

Where,

• CaO , is Calcium oxide(Quick lime).
• H20 is water .
• Ca(OH)2 is calcium hydroxide (slaked lime).

Extra information :-

Calcium oxide reacts with water to form calcium hydroxide, also called slaked lime. A lot of heat is produced in the reaction, which may even cause the water to boil. Hence it is a combination reaction as well as exothermic reaction.
