Elemental S reacts with O2 to form SO3 according to thereaction:
2S+ 3O2--> 2SO3
a.) How many molecules are needed to react with 5.74g of S?Express your answer numerically in units of molecules.
b.) What is the theoretical yield of SO3 produced by 5.74 g ofS? Express your answer numerically in grams.
Next, consider a situation in which all of the S is consumedbefore all of the O2 reacts, or one in which you have excess Sbecause all of the O2 has been used up.
c.) For each of the given situations, indicate whether S or O2is the limiting reactant. Drag each item to the appropriatebin.
Bins: Limiting reactant is sulfur, and Limiting reactant isoxygen
Choices:
Ă‚Â Ă‚Â - 3.0 mol sulfur, 4.0 mol of oxygen
Ă‚Â Ă‚Â - 3.0 mol sulfur, 3.0 mol oxygen
Ă‚Â Ă‚Â -3.0 mol sulfur, 5.0 mol oxygen
