I am pretty sure the answer is D. That the patterns of a polarity matched up on both sides.
Answer: There are 6.9 mol of 
are required to react completely with 2.30 mol of S.
Explanation:
The given reaction equation is as follows.
Here, 1 mole of S is reaction with 3 moles of which means 1 mole of S requires 3 moles of .
Therefore, moles of required to react completely with 2.30 moles S are calculated as follows.
Thus, we can conclude that there are 6.9 mol of are required to react completely with 2.30 mol of S.
