Explanation:
Detailed explanation-1: -Molarity of Ba(OH)2 solution =0.07 M.
Detailed explanation-2: -Explanation: Barium hydroxide, Ba(OH)2, is a strong base, so it will react with hydrochloric acid, HCl, a strong acid, to produce water and barium chloride, a soluble salt.
Detailed explanation-3: -Answer and Explanation: We are asked for the product of the reaction between hydrochloric acid, a strong acid, and barium hydroxide. The product is barium chloride, written as BaCl2 B a C l 2, and water is also formed.
