Question

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

Answer 1

Answer:

S(s) + O2(g) --> SO2(g)

Upper S (s) plus upper O subscript 2 (g) right arrow with delta above upper S upper O subscript 2 (g).

Explanation:

The reaction is given as;

Sulfur + oxygen --> Sulphur dioxide

Sulphur = S

Oxygen = O2

Sulfur dioxide = SO2

So we have;

S(s) + O2(g) --> SO2(g)

The crrect option is option A. Upper S (s) plus upper O subscript 2 (g) right arrow with delta above upper S upper O subscript 2 (g).

Answer 2

Answer:

Options a, b and c.

Explanation:

The reaction of production of SO₂ (sulfur dioxide) is the following:

S + O → SO₂(g)    (1)

The SO₂ can be produced by the combustion of materials that contain sulfur, thus the other alternative reactions of formation of SO₂ are the followings:

2H₂S + 3O₂ → 2H₂O + 2SO₂     (2)            

4FeS₂ + 11O₂ → 2Fe₂O₃ + 8SO₂    (3)            

The reaction (1) is exothermic, it produces temperatures of 1000–1600 °C.

A combination of the reactions (2) and (3) can be found in volcanic eruptions.

Therefore, the correct options are a, b and c. We discard the option d because that reaction produces SO₃ instead of SO₂.

I hope it helps you!
