Question

Write the balanced molecular equation for the neutralization reaction between hcl and ba(oh)2 in aqueous solution. include physical states.

Answer 1

Each Ba(OH)2 requires 2 Cl to produce one BaCl2 molecule. 

The 2 H's from the 2 HCl molecules combine with the 2 (OH) to form 2 H2O molecules. 

2 HCl (aq) + Ba(OH)2 (s) ==> BaCl2 (aq) + 2 H2O (l)

I hope the answer will help you. 

Answer 2

Answer: The balanced molecular equation is written below

Explanation:

A molecular equation is the chemical equation in which the ionic compounds are written as molecules rather than component ions.

Neutralization reaction is defined as the chemical reaction when an acid reacts with a base to produce a salt and water molecule.

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

$2HCl(aq.)+Ba(OH)_2(aq.)\rightarrow BaCl_2(aq.)+2H_2O(l)$

By Stoichiometry of the reaction:

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

Hence, the balanced molecular equation is written above.
