What type of reaction takes place when calcium oxide reacts vigorously with water to produce slaked lime?
Combination reaction
The correct answer is option 2 I.e. Combination reaction.
The reaction between calcium oxide (CaO) and water (H₂O) to produce slaked lime (calcium hydroxide, Ca(OH)₂) is a combination reaction.
In a combination reaction, two or more substances combine to form a single product. In this case:
CaO + H2 O → CaO(OH)2
This is an exothermic reaction, meaning it releases heat as calcium oxide reacts with water to form calcium hydroxide.
