1. Sulfuric acid is formed when sulfur dioxide gas reacts with oxygen gas and water. Write a balanced chemical equation for the
tekilochka [14]

Answer:

1. Balanced chemical for the given chemical reaction is :

2SO_2(g) +O_2(g) +2H_2O(l) \rightarrow  2H_2SO_4(aq)

number of mole of sulphuric acid produced = 12.5 mol

number of mole of oxygen required=6.25 mol

Explanation:

1. Balanced chemical for the given chemical reaction is :

2SO_2(g) +O_2(g) +2H_2O(l) \rightarrow  2H_2SO_4(aq)

from above balanced equation it is clearly that ,

2 mole of sulpher dioxide gives 2 mole of sulphuric acid

1 mole of sulpher dioxide gives 1 mole of sulphuric acid

therefore,

12 .5 mole of sulpher dioxide will givs 12.5 mole of sulphuric acid

number of mole of sulphuric acid produced = 12.5 mol

2 mole of sulphur dioxide needs 1 mole of oxygen gas

so,

1 mole of sulphur dioxide needs 0.5 mole of oxygen gas

therefore 12.5 of sulphur dioxide needs 12.5 \times 0.5mole of oxygen

number of mole of oxygen required=6.25 mol
