Question

explain the following reaction giving its balance chemical reaction calcium oxide is mixed with water

Answer 1

Cao + h2o ------- ca (OH)2

Calcium oxide reacts with water to form calcium hydroxide ( ca(OH)2)

Answer 2

explain the following reaction giving its balance chemical reaction calcium oxide is mixed with water?

ANSWER:-

◆ When Calcium Oxide (CaO) is mixed with Water (H2O)

EQUATION = CaO + H2O --- Ca(OH)2 + heat

◆ CaO = Calcium Oxide
H2O = water
Ca(OH)2 = Calcium Hydroxide

◆ In this reaction large amount ofheat will be released.

◆ It is Combination Reaction as well as Exothermic Reaction.

◆ 1] COMBUSTION REACTION = The reaction in which two or more substances combined to form one new substance.

2] EXOTHERMIC REACTION = The reaction in which heat will released.
