Hydrocarbons are organic compounds that are made up of only carbon and hydrogen atoms. A hydrocarbon was found to contain 84.63% of carbon by mass. Determine the empirical and the molecular formula of this hydrocarbon if 0.471 g of its vapour occupies a volume of 268 cm3 at 18 °C and 101 kPa

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
