4) Use Table 2.3 from your text book to determine the physical state (solid, liquid, or gas) of the following chemicals: Ethane, Ethanol, Hexane, Methane, Methanol, and Naphthalene. Note: Just do not state your answer, show how you determined the physical state of each of these pollutants using relevant physical properties listed in Table 2.3. TABLE 2.3 Some Physical and Chemical Properties of Various Chemicals. Log units represent base 10.
