Question

When water is added to a white powder 'A' vigoursly reaction
takes place and a large amount of heat is released 'A' is also used
for white washing Identify 'A', write a chemical equation for its
reation with water and name the product

Crumple Horned Nargle · Accepted Answer

'A' is quick lime (CaO) Quick lime reacts with
water vigorously and releases a large amount of heat and the
reaction is an exothermic reaction
CaO (s) + H2O â†’
Ca(OH)2+ heat
The product is Calcium hydroxide -
Ca(OH)2

When water is added to a white powder 'A' vigoursly reaction takes place and a large amount of heat is released. 'A' is also used for white washing. Identify 'A', write a chemical equation for its reation with water and name the product.
