Ca(OH)2
O CaO2 + H20
Ca(OH)2
CaO +H20
-Ca (OH)2

Answer 1

Answer:

Explanation:

CaO +H20 ----Ca (OH)2

Answer 2

The correct chemical reaction among the given reactions is:

CaO (s) + H2O (l) → Ca(OH)2 (s)

- When we react calcium oxide (or quick lime) with water, then the product formed is calcium hydroxide (or slaked lime).

- This is an exothermic reaction in which a very large amount of heat is liberated.

- It is also known as slaking of lime.

- It is the commercial method of manufacturing slaked lime.
