Final answer:
The reaction between 4 hydrogen molecules and 2 oxygen molecules produces 4 water molecules, making 4H₂O the correct answer.
Step-by-step explanation:
The reaction between 4H₂ (hydrogen gas) and 2O₂ (oxygen gas) would yield water as the product. When balancing the chemical equation, we find that 4 hydrogen molecules (4H₂) react with 2 oxygen molecules (2O₂) to form 4 water molecules (4H₂O). Hence, the correct balanced chemical reaction is:
4 H₂ + 2 O₂ → 4 H₂O
The balanced equation reflects the conservation of mass and the stoichiometric relationship between reactants and products. By comparing options a) H₂O₂, b) 2H₂O, c) 4H₂O, and d) 2H₂O₂, we can conclude that the correct answer is c) 4H₂O. This corresponds to the balanced reaction we've identified above.
