Two substances with crystal structures can be different even if the substances contain the same chemical elements in the same ratio. These substances have the same composition, but they are different because their atoms are arranged in different ways.Select the two models that represent substances with the same chemical formula but different arrangements of atoms.CSngraphite beta tin alpha tin Submit

Select the two models that represent molecules of substances with the same chemical formula but different arrangements of atoms.HCisobutylene cyclopropane butadiene 1-butene Next, complete the chemical formula for the two substances.If an atomic symbol has no subscript, leave the box next to the symbol blank.CH

Two substances can be composed of the same chemical elements and still be different.The molecules represented below are all composed of carbon and hydrogen. But each kind of molecule makes up a different substance. These substances are different because their molecules have different numbers of carbon atoms and hydrogen atoms.First, select the model of a molecule composed of two carbon atoms and six hydrogen atoms.HCethane propene ethyne Next, select the chemical formula for the substance composed of these molecules.C2H6C2H2C3H6Submit
