Balanced and skeletal equations are as following chemical equations. The number of atoms in each element on the reactant and product sides of a chemical reaction should match in order for the reaction to be considered balanced. The number of atoms on the reactant side and the product side of a skeletal equation are not equal.

Skeletal equation-

H₂ + O₂ → H₂O

Fe₂O₃ + H₂ → Fe + H₂O

Na + H₂O → NaOH + H₂

CuO+ O- →CuO

KI + Cl₂→ KCl+ I₂

Cr+ SnCl₄ → Sn + CrCl₃

Mg + CuSO₄ → MgSO₄ + Cu

ZnSO₄+ SrCl₂→ SrSO₄ZnCl₂

NH₄Cl + Pb(NO₃)₂→ PbCl₂ + NH₄NO₃

Fe(NO₃)₃ + MgS → Fe₂S₃ + Mg(NO₃)₂

Balanced Equation-

2H₂ + O₂ → 2H₂O

Fe₂O₃ + 3H₂ → 2Fe + 3H₂O

2Na + 2H₂O → 2NaOH + H₂

CuO+ O- →CuO

2KI + Cl₂→ 2KCl+ I₂

4Cr+ 3SnCl₄ → 3Sn + 4CrCl₃

Mg + CuSO₄ → MgSO₄ + Cu

ZnSO₄+ SrCl₂→ SrSO₄ZnCl₂

NH₄Cl + Pb(NO₃)₂→ PbCl₂ + NH₄NO₃

Fe(NO₃)₃ + MgS → Fe₂S₃ + Mg(NO₃)₂
