For each row in the table below, decide whether the pair of elements will form a molecular or ionic compound. If they will, then enter the chemical formula of the compound. If the elements will form more than one compound, enter the compound with the fewest total number of atoms. You may assume all chemical bonds are single bonds, not double or triple bonds. \begin{tabular}{|c|l|l|c|} \hline element \#1 & element \#2 & compound formed? & chemical formula \\ \hline neon & xenon & \begin{tabular}{l} ionic \\ molecular \\ neither \end{tabular} & $ \square $ \\ \hline rubidium & iodine & \begin{tabular}{l} ionic \\ molecular \\ neither \end{tabular} & \\ \hline strontium & oxygen & \begin{tabular}{l} ionic \\ molecular \\ neither \end{tabular} \\ \hline \end{tabular}

Suppose that the EPA has proposed strict controls on the amount of sulfur that diesel fuel contains. These controls were designed to fully offset the cost of pollution generated by diesel fuel vehicles. The effect of the regulation is estimated to increase the equilibrium price of a gallon of diesel fuel by 10 cents. Assuming that the supply of diesel fuel has a positive slope and demand has a negative slope, one can infer that the EPA determined that the external Multiple Choice benefit of using diesel fuel is less than 10 cents. cost of using diesel fuel is greater than 10 cents. cost of using diesel fuel is less than 10 cents. cost of using diesel fuel is equal to 10 cents.
