.

Write a balanced chemical equation with state symbols for the
following reactions.
(i) Solutions of barium chloride and sodium sulphate in water react
to give insoluble barium sulphate and the solution of sodium
chloride.
---
(ii) Sodium hydroxide solution in water) reacts with hydrochloric
acid solution in water) to produce sodium chloride solution and
water.​

Answer 1

Answer:

The reaction of  solutions of barium chloride and sodium sulphate in water react to give insoluble barium sulphate and the solution of sodium chloride is given by :

BaCl2(aq)+Na2SO4(aq) which gives --- BaSO_4(s)+2NaCl(aq)

sorry couldnt do the rest

Step-by-step explanation:

Answer 2

1. BaCl2 + Na2SO4 -----> BaSO4 + 2NaCl

2. NaOH + HCl ----> Nacl + H2O
