What equation correctly represents the combustion of acetone, C2H6O in excess of oxygen?

Answer 1

C₂H₆O + O₂ ==> CO₂ + H₂O ... unbalanced equation

First balance the carbon (C): C₂H₆O + O₂ ==> 2CO₂ + H₂O ... balanced for carbon

Next balance the hydrogen (H): C₂H₆O + O₂ ==> 2CO₂ + 3H₂O ... balanced for C and H

Finally, balance the oxygen (O): C₂H₆O + 3O₂ ==> 2CO₂ + 3H₂O ... BALANCED EQUATION
