How many moles of water are produced when 6.0 moles of hydrogen gas react with 2.5 moles of oxygen gas?

balanced equation: 2h2 + o2 → 2h2o

2.5 moles of water
3.0 moles of water
5.0 moles of water
6.0 moles of water

5.0 moles.

Explanation:

5.0 moles

Explanation:

   The balanced equation of the reaction between hydrogen and oxgen to produce water is:

H₂ + 1/2O₂ → H₂O.

   It is clear that 1.0 mole of H₂ reacts with 0.5 mole of O₂ to produce 1.0 mole of  H₂O.

∴ 2.5 mole of O₂ will react with 5.0 moles of H₂.

   The limiting reactant is O₂ and H₂ is found in excess (1.0 mole more).

From the stichiometry: 2.5 mole of O₂ will react with 5.0 moles of H₂ to produce 5.0 moles of  H₂O.

∴ 5.0 moles of water are produced when 6.0 moles of hydrogen gas react with 2.5 moles of oxygen gas
