Chemistry of the Environment

Air composition, greenhouse gases, acid rain and water — with an interactive exercise.

Chemistry of the Environment looks at air, water and pollution.

Clean air is about 78% nitrogen and 21% oxygen. Carbon dioxide is a greenhouse gas that traps heat and adds to global warming. Sulfur dioxide (and nitrogen oxides) cause acid rain.

Remember

  • Carbon dioxide → greenhouse gas.
  • Sulfur dioxide → acid rain.
