Question

balance ( a) sodium hydroxide reacts with hydroxide acid to form sodium chloride and water
(b) barium chloride reacts with liquid sodium sulphate to leave barium sulphate as precipitate and also with all separated symbols in paper and balance in paper

Answer 1

A)

Reaction :- Sodium Hydroxide + Hydroxide acid = Sodium Chloride + Water

Balanced equation :-

NaOH + HCl ---> NaCl + H2O it is already balanced

B)

Reaction :- Barium Chloride reacts with liquid Sodium Sulphate to leave Barium Sulphate

Balanced equation :-

BaCl2 (L) + Na2SO4 (L) ----> BaSO4 (S) + 2NaCl ( sodium chloride as salt, in liquid state)

Answer 2

Answer:

( a ). 2NaOH + 2HCl ➡️ 2NaCL + 2H2O

( Neutralisation Reaction)

( b ). BaCl2 + Na2SO4 ➡️ BASO4 + 2 NaCl

( Double Displacement Reaction)

_______________________________

Terms / Symbols :

▪️ NaOH = Sodium Hydroxide

▪️ HCl = Hydrochloric Acid

▪️ NaCl = Sodium Chloride

▪️ BaCl2 = Barium Chloride

▪️ Na2 SO4 = Sodium Sulphate

▪️ BaSO4 = Barium Sulphate

☆ All reactions are balanced.
