Detailed Explanation of Selected Compounds:
- Methane:
  - Colorless, odorless gas, simplest hydrocarbon.
  - Major component of natural gas, used as fuel.
  - Contributes to greenhouse gas effects and global warming.
- Carbon Dioxide:
  - Colorless, odorless gas, heavier than air.
  - Used in carbonation and fire extinguishing.
  - Also a significant greenhouse gas.
- Sodium Chloride:
  - Common salt, used in food and as a de-icing agent.
  - Plays a crucial role in bodily functions and is a source of sodium.
- Sodium Hydroxide:
  - Strong base, used in soap making and cleaning.
  - Highly soluble in water, releases heat upon dissolution.
- Calcium Carbonate:
  - Used in construction, as an antacid, and in agriculture to adjust soil pH.
- Sodium Bicarbonate:
  - Known as baking soda, used in baking and cleaning.
  - Acts as an antacid and is used in fire extinguishers.
- Acetone:
  - Colorless liquid, used as a solvent and nail polish remover.
  - Highly flammable and volatile.
- Urea:
  - Nitrogenous waste product, used as a fertilizer.
  - Significant in the urea cycle in mammals.
- Sodium Carbonate:
  - Known as washing soda, used in cleaning and glass production.
- Calcium Sulphate:
  - Used in agriculture and construction (as plaster of Paris).
