Here are 3 potential responses to the questions: 1. Common household chemicals like cleaners, air fresheners, and personal care products contain many different chemical components. Researching each component can help understand their individual and combined impacts on the environment if released. This knowledge helps make more informed choices about product selection and disposal. 2. Testing the effects of chemical components is important because mixtures can have properties different than their individual parts. Components that may seem harmless alone could interact in ways that harm the environment. Understanding these interactions helps identify risks and opportunities to formulate safer products. 3. Knowledge of mixtures and solutions provides a framework for analyzing complex environmental systems. The atmosphere, oceans, and soil contain many interacting substances from both natural
