Question

Look at the balanced equation below:

Answer 1

Answer:

11.5moles of oxygen gas

Explanation:

The reaction equation is shown below;

     C₂H₆O  + 3O₂ → 2CO₂  +  3H₂O

 We were given  11.5moles of H₂O produced;

Since the equation is balanced;

          3 mole of oxygen gas was used to produce 3 mole of water

        11.5 moles of water will be produced $\frac{11.5 x 3}{3}$   = 11.5moles of oxygen gas
