Answer:
a) Na₂O
b) Mg(NO₃)₂
c) AlCl₃
Explanation:
Symbol Valency
a) Sodium Oxide - Sodium Na 1
Oxygen O 2
1 2
(Cross Multiplication)
Na O
→ Na₂O₁ → Na₂O
b) Magnesium Nitrate - Magnesium Mg 2
Nitrate NO₃ 1
2 1
(Cross Multiplication)
Mg NO₃
→ Mg₁NO₃ → MgNO₃
c) Aluminium Chloride - Aluminium Al 3
Chlorine Cl 1
3 1
(Cross Multiplication)
Al Cl
→ Al₁Cl₃ → AlCl₃
