2. You have 15 grams of barium hydroxide, how many moles of water do you have?   HCl  +  Ba(OH)2  →  H2O  +  BaCl2

The correct answer is Ba(OH)_2+2HCl\rightarrow BaCl_2+2H_2OBa(OH)

2

+2HCl→BaCl

2

+2H

2

O

Explanation:

Neutralization reaction is defined as the reaction in which an acid reacts with a base to produce a salt and also releases water molecule.

The general equation for this reaction follows:

BOH+HX\rightarrow BX+H_2OBOH+HX→BX+H

2

O

The balanced chemical equation for the reaction of barium hydroxide and hydrochloric acid follows:

Ba(OH)_2+2HCl\rightarrow BaCl_2+2H_2OBa(OH)

2

+2HCl→BaCl

2

+2H

2

O

By Stoichiometry of the reaction:

1 mole of barium hydroxide reacts with 2 moles of hydrochloric acid to produce 1 mole of barium chloride and 2 moles of water molecule.
