Chem C asked:


The pressure in the cabin of an aircraft is less than atmospheric pressure. Scuba divers are advised not to travel by air for at least 24 hours after a dive. Explain what they might experience if they ignore this advice.

I need to know what the gas content of a scuba diving tank is. I found somewhere that is was 78% N2 and 21% O2, but that doesn’t seem right to me. If anyone has any answers I would appreciate it soooo much!!
