Here's a table showcasing some common gases, where they're produced, and a few examples of their uses:
| Gas | Production Source | Uses |
|---|---|---|
| Oxygen (O2) | - Photosynthesis by plants
- Industrial production by fractional distillation of air | - Respiration (breathing) by humans and animals
- Medical uses (oxygen therapy)
- Industrial processes (welding, combustion) |
| Carbon Dioxide (CO2) | - Respiration by humans and animals
- Combustion of fossil fuels
- Industrial processes | - Photosynthesis by plants
- Carbonated beverages
- Fire extinguishers |
| Nitrogen (N2) | - Fractional distillation of air | - Fertilizer production
- Food preservation (packaging)
- Manufacturing of explosives |
| Hydrogen (H2) | - Chemical reactions (e.g., electrolysis of water)
- Natural gas production | - Fuel for rockets and fuel cells
- Production of ammonia (fertilizer) |
| Helium (He) | - Extracted from natural gas deposits | - Filling balloons and blimps
- Cooling magnets in MRI machines |
| Methane (CH4) | - Decay of organic matter (e.g., landfills)
- Natural gas deposits | - Fuel for cooking and heating
- Production of electricity |
| Argon (Ar) | - Fractional distillation of air | - Welding (shielding gas)
- Filling incandescent light bulbs |
| Chlorine (Cl2) | - Industrial production from electrolysis of brine | - Disinfecting water
- Production of plastics and pesticides |
| Ammonia (NH3) | - Industrial production from nitrogen and hydrogen | - Fertilizer production
- Production of explosives and cleaning products |
| Sulfur Dioxide (SO2) | - Combustion of fossil fuels containing sulfur
- Industrial processes | - Production of sulfuric acid
- Food preservative |
