Chemistry of the Environment – Air Quality & Climate

Objective

State the symbol equation for photosynthesis:

\$6\,\mathrm{CO}2 + 6\,\mathrm{H}2\mathrm{O} \rightarrow \mathrm{C}6\mathrm{H}{12}\mathrm{O}6 + 6\,\mathrm{O}2\$

Think of Photosynthesis as a Factory

Imagine a plant as a tiny factory that uses sunlight as its power source. The factory takes in raw materials – carbon dioxide (CO₂) from the air and water (H₂O) from the soil – and produces food (glucose, C₆H₁₂O₆) and releases oxygen (O₂) as a by‑product. 🌞🏭🍃

Real‑World Example

If a plant receives 6 molecules of CO₂ and 6 molecules of H₂O, it will produce one molecule of glucose and 6 molecules of O₂. Think of it like baking a cake: you need 6 cups of flour (CO₂) and 6 cups of water (H₂O) to bake one cake (glucose) and you get 6 slices of cake (O₂) as a side dish! 🥞🍰

Why Photosynthesis Matters

  • Plants remove CO₂ from the atmosphere, reducing greenhouse gases.

  • They release O₂, which is essential for breathing.

  • They help regulate temperature by absorbing heat during the process.

Key Terms

  1. Reactants – substances that start the reaction.

  2. Products – substances formed after the reaction.

  3. Balanced Equation – the number of atoms on each side is equal.

Exam Tips

TipWhy It Matters
Write the full balanced equation.Examiners check for correct coefficients.
Remember the order: CO₂ first, then H₂O.It helps you avoid mixing up reactants and products.
Use the word “→” to show the reaction direction.Clear notation demonstrates understanding.

Quick Recap

Remember: \$6\,\mathrm{CO}2 + 6\,\mathrm{H}2\mathrm{O} \rightarrow \mathrm{C}6\mathrm{H}{12}\mathrm{O}6 + 6\,\mathrm{O}2\$. Think of it as a plant factory that turns sunlight into food and oxygen! 🌱✨
