Question

CaO+H2O gives Ca(OH)2. What is this reactions utility?

Answer 1

Hello Friend ✌
here is u r Ans ➡

✨CaO + H2O gives Ca (OH) 2

☄☄☄☄☄☄☄☄☄☄☄☄☄☄

⭐CaO ➡ Calcium oxide

⭐H2O ➡ Water

⭐Now,
CaO + H2O = Ca(OH)2

✨Ca(OH)2 ➡ Exothermic combination reaction

☄☄☄☄☄☄☄☄☄☄☄☄☄☄

✨In This Process, Calcium Oxide reacts with water to form Ca(OH)2

✨Due to This reaction, a large amount of heat generated.

Hope This Helps u ☺.

Answer 2

The reaction between calcium oxide (CaO) and water (H2O) to form calcium hydroxide Ca(OH)2 is an exothermic combination reaction. This reaction generates a lot of heat accompanied with hissing sound and thus is stated to be exothermic.
