Match the gases with their primary uses:

Importance of Gases in Air

Nitrogen: Used to make fertilizers and explosives
Oxygen: Used for respiration and supports burning, also causes rusting
Carbon Dioxide: Used for photosynthesis, putting out fires, making dry ice, and making breads and cakes rise. Also used to add fizz to beverages.
Water Vapour: Used to make rain clouds, takes part in many chemical reactions in plants and animals, transport materials in plants and animals, and removes waste from plants and animals.

Other Gases

Neon: Used to make bright lights; glows when electricity flows through a tube
Argon, Krypton, Xenon: Used in light bulbs because they do not react with metals, even when they get very hot.
Helium: Used to fill decorative balloons and weather balloons and also deep-sea diving mixtures because it is very light. Can be mixed with oxygen, nitrogen, or other gases as a safer alternative to pure oxygen
Hydrogen: Used to make margarine and fertilizers. Does not exist in our atmosphere beyond the space that we normally consider air.
