Final answer:

In the given chemical equation, there are 8 hydrogen atoms on the product side, as calculated by the number of moles of hydrogen gas produced (4 moles of H2 with 2 atoms each)(option d).

Step-by-step explanation:

In the chemical equation 3Fe + 4H₂O → Fe₃O₄ + 4H₂, the number of hydrogen atoms on the product side can be calculated by looking at the number of moles of hydrogen gas (H₂) produced.

Since there are 4 moles of H₂ and each mole contains 2 hydrogen atoms, the total number of hydrogen atoms on the product side would be 4 x 2, which equals 8 hydrogen atoms.

Therefore, the correct answer for the question "content loaded

In the equation 3Fe + 4H₂O → Fe₃O₄ + 4H₂, how many hydrogen atoms are on the product side?" is option d) 8.
