Question

Write a balanced chemical equation with state symbols for the
(iii) Sodium + Water
3.
following reactions.
Sodium hydroxide + Hydrogen
(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: a) Sodium + water --> sodium hydroxide + hydrogen. Symbol equation (balanced): 2Na(s) + 2H2O(l) --> 2NaOH(s) + H2(g)

b)The question given to us is, Sodium + Water → Sodium hydroxide + Hydrogen. The balanced Chemical Equation is 2Na+2H2O→2NaOH+H2.

c)Sodium hydroxide solution reacts with hydrochloric acid to form sodium chloride solution and water.

Explanation: Reaction of an acid and a base to form a salt and water is called neutralisation reaction. Here, cation from base and anion from acid combine to form a salt. OH- from base and H+ from acid combine to form water.

So try to write its balanced equation
