Question

Choose the mole ratio below that is INCORRECT based on the given balanced equation:

Answer 1

Answer:

4 moles CO₂ = 4 moles O₂

Explanation:

The incorrect mole ratio is 4 moles CO₂ = 4 moles O₂.

 Let us write the reaction equation:

          2C₂H₅OH + 7O₂ → 4CO₂ +  6H₂O

To write mole ratios in a chemical reaction, we must ensure the equation is balanced.

Since the given expression is balanced,

   Then 4 moles CO₂ = 4 moles O₂ is not correct;

 Rather;

            4 moles CO₂ = 7 moles O₂ is the right expression
