Question

025 Aqueous barium chloride and aqueous potassium carbonate react to produce solid

barium carbonate and aqueous potassium chloride.
A25
I need the balanced chemical equation for this

Answer 1

The balanced equation

BaCl₂(aq)+ K₂CO₃(aq)--> BaCO₃(s) + 2KCl(aq)

Further explanation

Given

word equation

Required

Balanced equation

Solution

Convert to chemical equation :

Reaction

BaCl₂(aq)+ K₂CO₃(aq)--> BaCO₃(s) + KCl(aq)

• Give a coefficient

aBaCl₂(aq)+ K₂CO₃(aq)--> bBaCO₃(s) + cKCl(aq)

• Make an equation

K, left = 2, right = c⇒c=2

C, left = 1, right = b⇒b=1

Ba, left = a, right = b⇒a=b⇒a=1

The equation becomes :

BaCl₂(aq)+ K₂CO₃(aq)--> BaCO₃(s) + 2KCl(aq)
