Question

Quizplus · Accepted Answer

The coefficient of FeS1U1P13+S1S1P0 in the reactants side is 1, while in the products side it is 12. Therefore, the coefficient must be changed by a factor of 12/1=12.

The coefficient of S1S1P0 in the reactants side is 1, while in the products side it is 1. Therefore, its coefficient does not need to be changed.

Therefore, the balanced equation is:

CNS1U1P1-S1S1P0 + 12FeS1U1P13+S1S1P0 → CNOS1U1P1-S1S1P0 + FeS1U1P12+S1S1P0S1U1P1 S1S1P0

The coefficient of FeS1U1P13+S1S1P0 is 12, so the answer is B.
