Question

Which formula equation represents the burning of sulfur to produce sulfur dioxide?

Answer 1

Answer:

$S_{(g)}+O_2_{(g)}\rightarrow SO_2_{(g)}$

Explanation:

Sulfur in the pressure of oxygen produces sulfur dioxide gas. The balanced chemical reaction is shown below as:-

$S_{(g)}+O_2_{(g)}\rightarrow SO_2_{(g)}$

The enthalpy change of the reaction is ΔH = -297 kJ/mol. This burning of sulfur reaction is exothermic in nature and this combustion can produce temperature of upto 1000 °C or more.

Sulfur in the elemental state oxidises and changes its oxidation number from 0 to +4 and oxygen reduces and changes its oxidation number from 0 to -2.

Answer 2

Balanced chemical equation: S(s) + O₂(g) → SO₂(g).

Sulfur change oxidation number from 0 to +4 (oxidation) and oxygen change oxidation number from 0 to -2 (reduction).

Sulfur dioxide (SO₂) is very common volcanic gas.

Fossil fuel combustion increases the acidity of rain because the sulfur dioxide is produced.  

Because of fuel combustion, sulfur dioxide goes up into the atmosphere as the hot gases rise, than it reacts with water and oxygen in the air and form sulfuric acid.
