The reaction you described seems to have a mistake in the number of reactant atoms. Typically, hydrogen (H) exists as diatomic molecules (H₂). So, if you mean four atoms of hydrogen reacting with two atoms of hydrogen, this would be a misunderstanding because molecules are typically involved in reactions.

If we assume you meant four hydrogen molecules (4 H₂) reacting with two hydrogen molecules (2 H₂), the total number of hydrogen atoms would be:

4 H₂ × 2 atoms/H₂ = 8 atoms
2 H₂ × 2 atoms/H₂ = 4 atoms

When combined:
8 atoms + 4 atoms = 12 hydrogen atoms.

However, if you mean they should react completely, typically the product would simply be more hydrogen molecules, not a different entity.

If you clarify the scenario a bit further, I can provide a more exact answer! But with the information given, the closest interpretation leads us to 8 (since 4 H₂ would yield 8 atoms when combined with 2 H₂ which also yields 4 atoms).

So, 8 could be the answer assuming correct interpretation or understanding of the reactants involved.

According to the law of conservation of mass, the total mass of the reactants must equal the total mass of the products in a chemical reaction.

In this case, if you react 20 grams of iron (Fe) with 15 grams of sulfur (S), the total mass of the reactants is:

\[
20 \, \text{grams (Fe)} + 15 \, \text{grams (S)} = 35 \, \text{grams}
\]

Therefore, the mass of the product should also be 35 grams.

So the correct answer is **35 grams**.
