A compound ‘A’ is used in the manufacture of cement. When dissolved in water, it evolves a large amount of heat and forms compound ‘B’.(i) Identify A and B.(ii) Write chemical equation for the reaction of A with water.(iii) List two types of reaction in which this reaction may be classified.

(i) A is Calcium Oxide (CaO) and B is calcium hydroxide Ca(OH)2.

(ii) The reaction is shown below:
$CaO + H_2O → Ca(OH)_2 + Heat$

(iii) The reaction can be known as a hydrolysis reaction (due to reaction with water) or exothermic reaction ( due to release of heat).
