Given the data from the question, the correct statement is:

  • One mole of water, H₂O was produced from the reaction

Basic concept

To know which options are correct, we shall determine the number of mole of O₂ used and the number of mole of H₂O produced.

How to determine the mole of  O₂ used

Balanced equation

2H₂ + O₂ —> 2H₂O

From the balanced equation above,

2 moles of H₂ required 1 mole of O₂

Therefore,

1 mole of H₂ will require = 1 / 2 = 0.5 mole of O₂

Thus, 0.5 mole of O₂ is needed for the reaction

How to determine the mole of H₂O produced

From the balanced equation above,

2 moles of H₂ reacted to produce 2 moles of H₂O

Therefore,

1 mole of H₂ will also react to to produce 1 mole of H₂O

Thus, 1 mole of H₂O was produced from the reaction.

SUMMARY

When 1 mole of H₂ was used in the reaction,

  • 0.5 mole of O₂ was used
  • 1 mole of H₂O was produced

Considering the options given in the question above, the correct statement is:

  • 1 mole of H₂O was produced
