Solution :
a) Hydrogen sulphide gas burns in air to give water and Sulphur dioxide
→ Here,
• Reactants : Hydrogen Sulphide and Oxygen
• Products : Water and Sulphur Dioxide
Equation formed :
\sf \: H_2S(g) + O_2 (g)\rightarrow \: H_2 O (l)+ SO_2(g)H
2
S(g)+O
2
(g)→H
2
O(l)+SO
2
(g)
Balanced Equation :
\sf \: 2H_2S(g) + 3O_2 (g)\rightarrow \: 2H_20 (l)+ 2SO_2(g)2H
2
S(g)+3O
2
(g)→2H
2
0(l)+2SO
2
(g)
b) Phosphorus burns in oxygen to give Phosphorus pentoxide
→ Here,
• Reactants : Phosphorus and Oxygen
• Product : Phosphorus Pentoxide
Equation formed :
\sf P(s) + O_{2} (g) \longrightarrow P_{4} O_{10} (s)P(s)+O
2
(g)⟶P
4
O
10
(s)
Balanced Equation:
\sf P_{4} (s) + 5O_{2} (g) \longrightarrow 2P_{2} O_{5}P
4
(s)+5O
2
(g)⟶2P
2
O

c) Carbon disulfide burns in air to give carbon dioxide and Sulphur dioxide
→ Here,
• Reactants : Carbon disulfide and oxygen
• Products : Carbon Dioxide and Sulphur Dioxide
Equation formed :
\sf \: CS_2(g) + O_2(g) \rightarrow CO_2(g) + S_20 (g) \:CS
2
(g)+O
2
(g)→CO
2
(g)+S
2
0(g)
Balanced Equation :
\sf \: CS_2(g) + 3O_2(g) \rightarrow CO_2(g) + 2S_20 (g) \:CS
2
(g)+3O
2
(g)→CO
2
(g)+2S
2
0(g)
d) Aluminium metal replaces iron from ferric oxide giving Aluminium oxide and iron.
→ Here,
• Reactants : Aluminum and Ferric Oxide
• Products : Aluminum Oxide and Iron
Equation formed :
\sf \: Al(s) + Fe_2O_3(s) \rightarrow Al_2O_3(s) + Fe (s)Al(s)+Fe
2
O
3
(s)→Al
2
O
3
(s)+Fe(s)
Balanced Equation :
\sf \: 2Al(s) + Fe_2O_3(s) \rightarrow Al_2O_3(s) + 2Fe (s)2Al(s)+Fe
2
O
3
(s)→Al
2
O
3
(s)+2Fe(s)
e) Barium Chloride reacts with zinc sulphate to give zinc chloride and Barium sulphate.
→ Here,
• Reactants : Barium Chloride and Zinc Sulphate
• Products : Zinc Chloride and Barium Sulphate
Equation formed :
\sf \: BaCl_2(s) + ZnSO_4(s) \rightarrow ZnCl_2(s) + BaSO_4(s)BaCl
2
(s)+ZnSO
4
(s)→ZnCl
2
(s)+BaSO
4
(s)
This equation is already balanced.
