Question: In the reaction 4Fe + 3O2 → 2Fe2O3, how many moles of Fe are required to react with 6 moles of O2?

Options:

Correct Answer: 8 moles

Solution:

From the balanced equation, 3 moles of O2 react with 4 moles of Fe. Therefore, 6 moles of O2 will require (4/3) * 6 = 8 moles of Fe.

In the reaction 4Fe + 3O2 → 2Fe2O3, how many moles of Fe are required to react with 6 moles of O2?

In the reaction 4Fe + 3O2 → 2Fe2O3, how many moles of Fe are required to react with 6 moles of O2?

Step 1: Look at the balanced chemical equation: 4Fe + 3O2 → 2Fe2O3.
Step 2: Identify the ratio of Fe to O2 from the equation. It shows that 4 moles of Fe react with 3 moles of O2.
Step 3: Determine how many moles of Fe are needed for 6 moles of O2. We can set up a proportion based on the ratio.
Step 4: Use the ratio: (4 moles of Fe / 3 moles of O2) = (x moles of Fe / 6 moles of O2).
Step 5: Cross-multiply to solve for x: 4 * 6 = 3 * x.
Step 6: This simplifies to 24 = 3x.
Step 7: Divide both sides by 3 to find x: x = 24 / 3 = 8.
Step 8: Therefore, 8 moles of Fe are required to react with 6 moles of O2.
