Question

The following balanced equation shows the formation of sulfur dioxide.

Answer 1

Ans: C) 15.0 mol

Given:

Chemical reaction:

S + O2 → SO2

Moles of SO2 produced = 15.0 mol

To determine:

Moles of S needed

Explanation:

Based on the stoichiometry of the given reaction:

1 mole of S is required to produce 1 mole of SO2

Therefore, # moles of S required to produce 15.0 mol of SO2 is

= 15.0 mol SO2 * 1 mol S/1 mol SO2 = 15.0 mol S

Answer 2

actually the answer is C. 15.0 on ed
