Chemical plants sometimes use water for their cooling processes. The water absorbs that thermal energy and gets released into bodies of water with living organisms (lakes, rivers, etc). This results in less dense hot water to float on top while cool water sinks below it. How does this affect marine life under? (Clue: Use concept of solubility of gases in high temperatures) *

Part 1: The structures of carbon disulfide and carbon dioxide are shown below with their boiling points. Explain why CS2 has a higher boiling point than CO2. Be specific about particulate interactions and intermolecular forces. IMG 2217 Part 2: Below are the structures of water and octane (C8H18), along with their boiling points. Water has a lower boiling point than octane! Explain why, being specific about the particulate-level interactions and intermolecular forces. (Remember, each point on a line is a carbon surrounded with the appropriate number of hydrogen atoms to make an octet). IMG 2218
