2. Paraffin and gasoline are both hydrocarbons, and therefore have the same general
chemical formula CnHn+2. As such, paraffin and gasoline are similar in that both do
not contain oxygen. Compare the use of gasoline (which would be similar to
paraffin) versus ethanol as a fuel, considering that gasoline is a hydrocarbon
whereas ethanol also contains oxygen. Compare the use of gasoline versus ethanol
as a fuel, from the standpoint of efficiency, by comparing the amount of energy that
each contains on a per amount of fuel basis.

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
