Answer:

4 molecules

4 molecules

0.75

4 molecules

Explanation:

Based on the reaction:

3Fe + 4H₂O → Fe₃O₄ + 4H₂

3 moles of Iron (Fe) reacts with 4 moles of water (H₂O) producing 3 moles of ferrous ferric oxide (Fe₃O₄) and 4 moles of hydrogen (H₂).

Thus, if 3 molecules of Fe react:

How many molecules of Hâ‚‚ are produced?

4 molecules

How many water molecules are required?

4 molecules

What is the mole ratio of Fe to Hâ‚‚O?

3 moles Fe per 4 moles of Hâ‚‚O. Ratio is:

3/4 = 0.75

How many hydrogen molecules (Hâ‚‚) are involved in this reaction?

Again, 4 molecules
