Question

name the reaction between cao and water? what is the effect ?
appropriate answers needed

Answer 1

Calcium oxide reacts with water to form calcium hydroxide, also called slaked lime. A lot of heat is produced in the reaction, which may even cause the water to boil.

Answer 2

CaO + H2O → Ca(OH)2

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

• A combination reaction is a reaction in which two reactants combine to form one product. Oxygen and halogens are very reactive elements and undergo combination reactions with other elements.
• This is an exothermic chemical reaction and gives off heat.
