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

2 C2H5OH + 7 O2 --> 4 CO2 + 6 H2O

O 2 moles C2H5OH = 4 moles CO2

O 7 moles O2 = 2 moles C2H5OH

O 4 moles CO2 = 4 moles O2

O 6 moles H2O = 7 moles O2

Answer:

4 moles COâ‚‚ = 4 moles Oâ‚‚

Explanation:

The incorrect mole ratio is 4 moles COâ‚‚ = 4 moles Oâ‚‚.

 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
