The balanced equation :
(NH₄)₂CO₃ + MgSO₄ ----> (NH₄)₂SO₄ +MgCO₃
Further explanation
Given
Reaction
(NH4)2CO3 + MgSO4 ----> (NH4)2SO4 + MgCO3
Required
The balanced equation
Solution
Give a coefficient
a(NH₄)₂CO₃ + bMgSO₄ ----> (NH₄)₂SO₄ +cMgCO₃
Make an equation
N, left=2a, right=2⇒2a=2⇒a=1
S, left=b, right=1⇒b=1
C, left=a, right=c⇒a=c=1
The equation becomes :
(NH₄)₂CO₃ + MgSO₄ ----> (NH₄)₂SO₄ +MgCO₃
