Answer:

C. One mole of water was produced from this reaction.

Explanation:

  • From the balanced equation:

<em>2H₂ + O₂ → 2H₂O,</em>

It is clear that 2 mol of H₂ react with 1 mol of O₂ to produce 2 mol of H₂O.

  • So, if one mole of hydrogen was used in this reaction:

1/2 mol of O₂ was used in the reaction, and

1 mol of water was produced from this reaction.

  • So, the correct statement is:

<em>C. One mole of water was produced from this reaction. </em>
