Sulfur and oxygen react in a combination reaction to produce sulfur trioxide, an environmental pollutant: 2S(s) + 3O2(g) → 2SO3(g) In a particular experiment, the reaction of 1.0 g S with 1.0 g O2 produced 0.80 g of SO3. The % yield in this experiment is .

54\%

Explanation:

Hello,

In this case, the first step is to identify the limiting reagent by considering the shown below procedure in terms of the reacting sulfur:

Thus, since 1.0 g of oxygen would consume 0.0185 mole of sulfur and there are 0.03125 mole available, oxygen is the limiting reagent, in such a way, the theoretical yield turns out:

Finally, the percent yield:

Best regards.

the answer is
