Answer:
in this reaction, 4 moles of H₂ will react with 2 moles of O₂ to produce 4 moles of H₂O.
Step-by-step explanation:
The balanced equation 2H₂ + O₂ → 2H₂O tells us that 2 moles of hydrogen gas (H₂) will react with 1 mole of oxygen gas (O₂) to produce 2 moles of water (H₂O).
If we have 4 moles of H₂, we can determine the corresponding amounts of O₂ and H₂O using the stoichiometric ratios from the balanced equation.
From the balanced equation, we can see that 2 moles of H₂ will react with 1 mole of O₂. Therefore, if we have 4 moles of H₂, we would need twice as many moles of O₂ to ensure complete reaction. Thus, we would require 2 moles of O₂.
Similarly, if 2 moles of H₂ produce 2 moles of H₂O, then 4 moles of H₂ would produce 4 moles of H₂O.
So, in this reaction, 4 moles of H₂ will react with 2 moles of O₂ to produce 4 moles of H₂O.
