Answer :

Final answer:

The answer explains greenhouse gases and provides examples of different types of solutions and intermolecular attractions.


Explanation:

Greenhouse gases: Carbon dioxide (CO₂) is a greenhouse gas that contributes to global warming. It absorbs and emits radiation within the thermal infrared range.

Types of solutions:

  1. a) Gas in a liquid: Carbon dioxide in water (carbonated water).
  2. b) Gas in a gas: Oxygen and other gases in nitrogen (air).
  3. c) Solid in a solid: Example not provided in the context.

Intermolecular attractions: The types of attractions differ based on the specific solutes and solvents involved in the solutions mentioned.
