Virty [35]

Balanced equation

2Al(ClO₃)₃ + 3BaSO₄⇒ Al₂(SO₄)₃ + 3Ba(ClO₃)₂

<h3>Further explanation</h3>

Given

Word equation

Required

Chemical equation

Solution

Chemical equations can be expressed in

  • word equation
  • skeleton equation
  • balanced equation

Aluminum chlorate = Al(ClO₃)₃

Barium sulfate = BaSO₄

Aluminum sulfate = Al₂(SO₄)₃

Barium chlorate = Ba(ClO₃)₂

  • Skeleton equation

Al(ClO₃)₃ + BaSO₄⇒ Al₂(SO₄)₃ + Ba(ClO₃)₂

  • Balanced equation

2Al(ClO₃)₃ + 3BaSO₄⇒ Al₂(SO₄)₃ + 3Ba(ClO₃)₂
