Which gas is used in scuba diving tanks?

For normal "sport" diving, scuba tanks are filled with just plain old air! That's just the mix of gases you're likely breathing right now, and it contains 78% Nitrogen, 21% Oxygen, and 1% other gases. But nitrogen can cause problems for divers ("bends" and "narcosis"). So for technical diving (below 100 feet), divers sometimes use Nitrox, less nitrogen than normal air, and more oxygen. But even pure oxygen can be dangerous when breathed under pressure. In fact, breathing pure oxygen while scuba diving below 25 feet can be fatal! So for very deep technical dives, the inert gas helium is often added into the gas mix; which can be heliox (oxygen & helium), or trimix (oxygen, helium, and nitrogen).

Do ions need nitrogen tanks?

Yes, they require High pressure air (nitrogen) tanks. They cannot run off of CO2.

Mixture of gases for scuba diving tanks compared to normal atmospheric air?

Most SCUBA divers dive with compressed air, which is normal atmospheric air compressed into a scuba tank.

What is the air in a scuba tank made of?

Most scuba tanks are filled with simple purified air. However, some are filled with oxygen enriched air called 'nitrox' or (less commonly) a blend of helium, oxygen and nitrogen called 'trimix' or (even less commonly) helitrox or heliox.

What happens after using the scuba tank?

A cardinal rule for scuba diving tanks is to never completely empty your scuba diving tank. When planning your scuba dives, it is important that you consider to complete your dive with enough air left within your scuba diving tank.

Is the oxygen and nitrogen in a scuba tank considered a heterogeneous?

I would think so, because there are two of them mixed together. Air in a scuba tank or anywhere else should be heterogeneous. A scuba tank filled with either oxygen or nitrogen would be homogeneous.
