When ethanol, C2H5OH (a component in some gasoline mixtures) isburned in air, one molecule of ethanol combines with three oxygenmolecules to form two CO2 molecules and three H2O molecules.
a)Â Â Â Â Â Draw two molecular-sized models:one for the reactant mixture and one the product mixture! Usedifferent colors or different shading to indicate the identity ofthe atoms.
b)Â Â Â Â Â Write the balanced chemicalequation for the reaction described.
c)Â Â Â Â Â How many molecules ofCO2 and H2O would be produced when 2 molecules ethanolare consumed? Equation?
d)Â Â Â Â Â How many H2O molecules areformed, then 9 O2 molecules are consumed? What conversion factordid you use? Explain!
e)Â Â Â Â Â If 15 ethanol molecules react,how many molecules O2 must also react? What conversion factor didyou use? Explain!
