Which equation represents the reaction of sulfur with oxygen to form sulfur trioxide?

A. 2S + 3O2 --> 2SO3
B. S + O --> SO3
C. 3S + O2 --> SO3
D. 6S + 3O2 --> 2SO3

Answer :

2s + 302 ----> 2S03 A is correct

Answer: The correct answer is Option A.

Explanation:

All the balanced chemical equations follow Law of conservation of mass. This law states that the total number of individual atoms present on the reactant side is always equal to the total number of individual atoms present on the product side.

The balanced chemical equation for this reaction follows:

[tex]2S+3O_2\rightarrow 2SO_3[/tex]

By Stoichiometry of the reaction:

2 moles of sulfur reacts with 3 moles of oxygen gas to produce 2 moles of sulfur trioxide.

Hence, the correct answer is Option A.
