Question

1. Translate the following statements into chemical Equations and the balance the equations
1. Hydrogen sulphide gas burns in air to give water and sulphur dioxide
II. Phosphorus burns in oxygen to give phosphorus pentoxide
III. Carbon disulphide burns in air to give carbon dioxide and sulphur dioxide
IV. Aluminium metal seplaces iron from ferric oxide, Fe,0, giving aluminium oxide and iron
V. Barium chloride reacts with zinc sulphate to give zinc chloride and barium sulphate

​

Answer 1

Answer:

I.

2H2S +3O2 -->2 H2O +2SO2

II. P4 +5O2 --->2 P2O5

III. CS2 +3O2 ----> CO2 +2SO2

IV. 2Al +Fe2O3 ---->2 Fe + Al2O3

V. BaCl2 +ZnSO4 ----->BaSO4 +ZnCl2

Explanation:

Balance reaction in such way as number of atoms of each element are same on both the sides of the equation.

Answer 2

Answer:

I. 2(H2S) + 3(O2) => 2(H2O) + 2(SO2)

II. 4(P) + 10(O) => (P4O10)

III. (CS2) + 3(O2)=> (CO2) + 2(SO2)

IV. (BaCl2) + (ZnSO4) => (ZnCl2) + (BaSo4)
