Question

Find the moles of sulfur produced, if 2.5 moles of sulfur dioxide are used in the following chemical reaction: SO2 + 2H2S → 2H2O + 3S

Select one:
b. 1.25 mol
c. 7.5 mol
d. None of the above
e. 2.50 mol
(A WAS WRONG!!!! so I took it out but A is 0.833 mol)

Answer 1

2.5 moles of sulfur dioxide (SO2) react to produce 7.5 moles of sulfur (S), based on the stoichiometry of the given chemical reaction. So the correct option is c

Step-by-step explanation:

To calculate the moles of sulfur produced from the reaction of 2.5 moles of sulfur dioxide (SO2), we need to use the stoichiometry of the given balanced chemical reaction:

SO2 + 2H2S → 2H2O + 3S

From the reaction, we see that one mole of SO2 produces 3 moles of sulfur (S). Therefore, if 2.5 moles of SO2 are reacted, we can calculate the moles of sulfur produced by multiplying 2.5 moles by the stoichiometric coefficient of S, which is 3:

2.5 moles SO2 × 3 moles S per 1 mole SO2 = 7.5 moles S

Therefore, the moles of sulfur produced are 7.5 moles.

Answer 2
