Question: In the reaction 4Fe + 3O2 → 2Fe2O3, how many moles of Fe2O3 can be produced from 8 moles of Fe?

Options:

Correct Answer: 4 moles

Solution:

From the balanced equation, 4 moles of Fe produce 2 moles of Fe2O3. Therefore, 8 moles of Fe will produce 4 moles of Fe2O3.

In the reaction 4Fe + 3O2 → 2Fe2O3, how many moles of Fe2O3 can be produced from 8 moles of Fe?

In the reaction 4Fe + 3O2 → 2Fe2O3, how many moles of Fe2O3 can be produced from 8 moles of Fe?

Step 1: Look at the balanced 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 Fe2O3 can be produced from 8 moles of Fe. Since 4 moles of Fe produce 2 moles of Fe2O3, we can set up a proportion.
Step 4: Calculate the number of moles of Fe2O3 produced from 8 moles of Fe. If 4 moles of Fe produce 2 moles of Fe2O3, then 8 moles of Fe will produce (8 moles Fe / 4 moles Fe) * 2 moles Fe2O3.
Step 5: Simplify the calculation: (8 / 4) * 2 = 2 * 2 = 4 moles of Fe2O3.
