A compound found in an oil extracted from the leaves of a tree is isolated for study. It is found to contain carbon, hydrogen, and oxygen. Combustion analysis determines that the compound is 77.87% C and 11.76% H. What is the empirical formula of the unknown compound?

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.
