In this case, the answer is no due the fact that cyclic alkenes contain π bonds that are not conjugated or partially conjugated but not abided by the Huckel 4n+2 π electron system in a conjugated structure. However, aromatic hydrocarbons are likely to react with electrophilic species to promote electrophilic substitution yet cyclic alkenes does not.
No, they don't behave similarly since in aromatic hydrocarbons, the electron density is uniform whereas in cyclic alkenes, electron density is not uniform
There are approximately 160 grams in 1 mol of Fe2O3 molecules. Therefore, there would be 79/160= 0.49375 mols of Fe2O3 molecules in 79 grams. There are 5 atoms in total for each molecule of Fe2O3, therefore 79/160 * 5 = 79/32 = 2.46875 mols of atoms.
