CHEM 210 Module 2 Exam Newest 1. a higher melting or boiling point indicates the molecule has: stronger inter- molecular forces. 2. What is the shape of water?: Bent. The bond angle is 104.5 degrees. 3. What is autoionization, and how is it important for water?: Autoionization is the ability of a compound to react with itself to form ions. One water molecule reacts with a second molecule to form two ions: H3O+ and OH-. These ions exist in ...

ACS Biochemistry 2023-2024 Exam Questions with All Correct Answers Metabolism (catabolism and anabolism) - ANSWER Metabolism: sum of total chemical reactions in an organism, also the method by which cells extract and use energy from their environment. Catabolism: The process by which stored nutrients and ingested foods are converted to a usable form of energy. It produces simple products CO2, H2O, NH3, and building blocks such as sugars and fats that are used in anabolism. Anaboli...
