Respuesta :

The number of moles of iron (Fe) required to react with 3.82 moles of oxygen is 5.09 moles

Balanced equation

3O₂ + 4Fe —> 2Fe₂O₃

From the balanced equation above,

3 moles of O₂ reacted with 4 moles of Fe

How to determine the moles of Fe

From the balanced equation above,

3 moles of O₂ reacted with 4 moles of Fe

Therefore,

3.82 moles of O₂ will react with = (3.82 × 4) /  3 = 5.09 moles of Fe

Thus, 5.09 moles of Fe is needed for the reaction
