answer the following questions in the space provided. 24. explain how chemicals and chemical reactions are an important part of your life. 25. in the spaces below draw and label a microscopic view showing the particles in a solid, a liquid, and a gas.

Explanation:

Question 24

Chemicals and reactions are vital. For example, digestion (enzymes break food), respiration (glucose + O₂ → energy), cleaning (detergents react with dirt), and photosynthesis (plants make food). These processes sustain life, enable daily tasks, and support ecosystems.

• Solid: Draw closely packed, ordered particles (e.g., circles) with labels like "Fixed position, strong attraction".
• Liquid: Draw particles close but less ordered, moving freely (labels: "Close, can slide, moderate attraction").
• Gas: Draw widely spaced particles moving randomly (labels: "Far apart, fast motion, weak attraction").

Answer:

Chemicals and chemical reactions are essential. Digestion (enzymes break food), respiration (glucose + O₂ produces energy), cleaning (detergents react with dirt), and photosynthesis (plants make nutrients) are examples. They sustain life, enable daily activities, and support ecosystems.
