Answer 2

Answer:

A researcher adds barium hydroxide to hydrochloric acid to form a white-colored barium chloride. Which option gives the balanced chemical equation of the reaction?   HCl + 2Ba(OH) → 2BaCl2 + 2HOH + O2  HCl + Ba(OH)2 → BaCl2 + 2HOH  2HCl + Ba(OH)2 → BaH2 + 2HCl + O2  2HCl + Ba(OH)2 → BaCl2 + 2HOH

Explanation:

The balanced chemical reaction is given below -

The correct balanced chemical reaction is - (b) 2HCl + Ba(OH)2 -----------> BaCl2 + 2HOH

At the reactant side, 4 Hydrogen atoms, 2 chlorine atoms are present along with 2 oxygen atom and 1 atom of barium.

So, product side will contain 1 barium atom, 2 chlorine and oxygen atoms and 4 atoms of hydrogen are present.

Barium chloride finds application in purification of brine, case hardening of steel etc.
