Explain why HCl is a strong acid and CH3COOH is a weak acid. How can it be verified? The Correct Answer and Explanation is: Answer:HCl is a strong acid because it completely ionizes in water, releasing all of its hydrogen ions (H⁺). CH₃COOH (acetic acid) is a weak acid because it only partially ionizes in […]

Dehydration Synthesis and Hydrolysis: Carbohydrates, proteins, and lipids are all synthesized and broken down by the same types of reactions. In dehydration synthesis, a hydrogen ion (H+) from one molecule joins with a hydroxyl group (OH-) from another molecule to form water (H2O), leaving the two molecules bonded to the same oxygen atom. For example,
