Read the chemical equation. 2c2h2 + 5o2 → 4co2 + 2h2o which of the following statements would be correct if one mole of c2h2 was used in this reaction? one mole of oxygen was used in this reaction. five moles of oxygen were used in this reaction. four moles of carbon dioxide were produced from this reaction. two moles of carbon dioxide were produced from this reaction.

Two moles of carbon dioxide were produced from this reaction.

Explanation:

2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O,

It is clear that 2 mol of C₂H₂ react with 5 mol of O₂ to produce 4 mol of CO₂ and 2 mol of H₂O.

C₂H₂ + 5/2O₂ → 2CO₂ + H₂O,

It is clear that 1 mol of C₂H₂ reacts with 2.5 mol of O₂ to produce 2 mol of CO₂ and 1 mol of H₂O.

Two moles of carbon dioxide were produced from this reaction.
