Question

In order to illustrate a combination reaction, a teacher take about 2g to 3g calcium oxide
in a glass beaker and pour water over it very slowly.
Based on the given information:
(i) Write the chemical reaction involved in this process.​

Answer 1

Answer:

CAO + H2O ---------- CA(OH)2

Explanation:

calcium oxide reacts with water to form calcium hydroxide

CAO + H2O ---------- CA(OH)2

Answer 2

Explanation:

i) CaO + H2O-> CA(OH)2+ heat

ii calcium oxide reacts vigorously with water to produce slaked lime releasing a large amount of heat
