This reaction is a combination reaction, as calcium oxide and water combines to form a single product that is calcium hydroxide.
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.
2Na + Cl2 → 2NaCl
