Question

Calcium hydroxide + hydrochloric acid → calcium chloride + water

Answer 1

Answer : The correct balanced chemical reaction will be:

$Ca(OH)_2(aq)+2HCl(aq)\rightarrow CaCl_2(s)+2H_2O(aq)$

Explanation :

When calcium hydroxide react with hydrochloric acid then it react to give calcium chloride and water as a product.

This reaction is double-displacement reaction.

Double-displacement reaction : It is defined as the reaction in which the cation of two reactants molecule exchange their places to give two different products.

Thus, the correct balanced chemical reaction will be:

$Ca(OH)_2(aq)+2HCl(aq)\rightarrow CaCl_2(s)+2H_2O(aq)$

Answer 2

Answer:

D

Explanation: iIt is a neutralization reaction and neutralization reaction is a reaction between and acid and base to give salt and water. In the question above, Ca(OH)2 is the base and HCl is the acid, Ca(Cl)2 is the salt and H2O.
