CaO + H₂O → Ca(OH)₂ is an example of which reaction?

Answer:

This reaction is a combination reaction, as calcium oxide and water combines to form a single product that is calcium hydroxide.

Combination reaction

A reaction in which two or more reactants combine to form a single product is known as a combination reaction.

A general form of combination reaction is

X + Y → XY

A combination reaction is also known as a synthesis reaction.

When calcium oxide (commonly known as quick lime) reacts with water, then it combines with water and forms calcium hydroxide (commonly known as slaked lime).

CaO + H₂O → Ca(OH)₂

Calcium oxide + Water  → Calcium hydroxide

The product of this reaction is calcium hydroxide, also known as slaked lime. This reaction is an example of a combination reaction.

Example

2Na + Cl₂ → 2NaCl
