Answer:
Atoms consist of a nucleus made of protons and neutrons orbited by electrons.
Isotopes are atoms that have same number of protons but they differ in the number of neutrons and in atomic mass.
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
Al(ClO₃)₃ + BaSO₄⇒ Al₂(SO₄)₃ + Ba(ClO₃)₂
2Al(ClO₃)₃ + 3BaSO₄⇒ Al₂(SO₄)₃ + 3Ba(ClO₃)₂
