Question

to pour water on calcium oxide.which is another way to classify this reaction ? explain

Answer 1

CaO+H2O-> Ca(OH)2

This is combination reaction where 2 or more reactants react together to form a single product

This is also an exothermic reaction as heat is liberated during this reaction

Answer 2

When water is added to calcium oxide (quicklime), it will be converted to calcium hydroxide (slaked lime) with the liberation of enormous amount of heat.

CaO+H₂O=Ca(OH)²+heat

It is an exothermic reaction.

Calcium hydroxide is an alkali.
