Suppose 5.5 g of Compound A are consumed in a reaction with 3.5 g of Compound B that produces only one product,
Compound C.
To determine the limiting reactant in this reaction, we need to calculate the molar amounts of Compound A and Compound B.
Step 1: Calculate the molar mass of each compound
The molar mass of Compound A = ? g/mol
The molar mass of Compound B = ? g/mol
Step 2: Calculate the moles of each compound
moles of Compound A = 5.5 g / molar mass of Compound A
moles of Compound B = 3.5 g / molar mass of Compound B
Step 3: Determine the limiting reactant
To determine the limiting reactant, we compare the moles of Compound A to the moles of Compound B. The reactant with the smaller amount of moles is the limiting reactant.
Step 4: Calculate the theoretical yield of Compound C
Once we have determined the limiting reactant, we can calculate the theoretical yield of Compound C using stoichiometry. We need to look at the balanced chemical equation for the reaction between Compound A and Compound B to determine the mole ratio of reactants to product.
Step 5: Calculate the actual yield of Compound C
To calculate the actual yield of Compound C, we need to know the amount of limiting reactant consumed in the reaction, which we already know is 5.5 g of Compound A. We also need to calculate the actual amount of Compound C produced based on the mole ratio determined in step 4.
By following these steps, we can determine the limiting reactant in the reaction between Compound A and Compound B and calculate the theoretical and actual yield of Compound C.
