When ethanol, C2H5OH (a component in some gasoline mixtures) is burned in air, one molecule of ethanol combines with three oxygen molecules to form two CO2 molecules and three H2O molecules.

a) Draw two molecular-sized models: one for the reactant mixture and one the product mixture! Use different colors or different shading to indicate the identity of the atoms.

b) Write the balanced chemical equation for the reaction described.

c) How many molecules of CO₂ and H2O would be produced when 2 molecules ethanol are consumed? Equation?

d) How many H2O molecules are formed, then 9 O2 molecules are consumed? What conversion factor did you use? Explain!

e) If 15 ethanol molecules react, how many molecules O2 must also react? What conversion factor did you use? Explain!

Ethanol (C2H5OH) and gasoline (C8H18) are both used as automobile fuel. If gasoline is selling for $2.50/gal, what would the price of ethanol have to be in order to provide the same amount of heat per dollar? Necessary ΔH°f values are found in the table below. The density of octane is 0.7025 g/mL and the density of ethanol is 0.7894 g/mL. 1 gal = 3.785 L. C8H18(l) + 25/2 O2(g) → 8CO2(g) + 9H2O(g) C2H5OH(l) + 3O2(g) → 2CO2(g) +...
