Elemental S reacts with O2 to form SO3 according to thereaction
2S+3O2→2SO3
A) How many O2 molecules are needed to react with 4.13 g ofS?
Express your answer numerically in units of molecules.
B) What is the theoretical yield of SO3 produced by thequantities described in Part A?
Express your answer numerically in grams.
C) 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.
For each of the given situations, indicate whether S or O2 isthe limiting reactant.
- 3.00 mol Sulfur, 3.00 mol Oxygen
-3.00 mol Sulfur, 4.00 mol Oxygen
-3.00 mol Sulfur, 5.00 mol Oxygen
