Q
Q: In the reaction 4Fe + 3O2 → 2Fe2O3, how many moles of Fe2O3 can be produced from 12 moles of Fe?
Solution:
From the stoichiometry, 4 moles of Fe produce 2 moles of Fe2O3. Therefore, 12 moles of Fe will produce (12/4) x 2 = 6 moles of Fe2O3.
Steps: 6
Show Steps
Step 1: Look at the chemical equation: 4Fe + 3O2 → 2Fe2O3.
Step 2: Identify the ratio of Fe to Fe2O3 from the equation. It shows that 4 moles of Fe produce 2 moles of Fe2O3.
Step 3: Determine how many moles of Fe you have. In this case, you have 12 moles of Fe.
Step 4: Use the ratio from Step 2 to find out how many moles of Fe2O3 can be produced from 12 moles of Fe.
Step 5: Set up the calculation: (12 moles of Fe / 4 moles of Fe) x 2 moles of Fe2O3.
Step 6: Calculate the result: (12 / 4) x 2 = 3 x 2 = 6 moles of Fe2O3.
