The correct equation that has the same coefficients in the same order as 2CO2 + 3H2O -> C2H6O + 3O2 is CH4 + O2 -> CO2 + H2O. The other equations do not have the same coefficients in the same order as the given equation.
In the given equation, there are 2 molecules of CO2 and 3 molecules of H2O on the reactant side, and 1 molecule of C2H6O and 3 molecules of O2 on the product side. In the equation CH4 + O2 -> CO2 + H2O, there are 1 molecule of CH4 and 1 molecule of O2 on the reactant side, and 1 molecule of CO2 and 1 molecule of H2O on the product side. The coefficients of the elements in the given equation and this equation are the same and in the same order.
