Question

when quicklime is added to water Calcium Hydroxide is formed.

(1) list any two absorption in the reaction
(2)write the balanced chemical equation​

Answer 1

Answer:

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+H

2

O→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

❥A᭄ɴsᴡᴇʀ࿐:

(1) Two observation are:-

• Release of heat (Exothermic reaction).
• Combination Reaction takes place.
• Slaked lime { Ca(OH)2 } is formed as a product.

(2) Balanced chemical reaction for the reaction

Cao+H2O------Ca(OH)2+ ∆ .
