what type of gas is contained in a scubadiving tank?

OH LET ME THINK.....WHAT IS THE GAS THAT HELP US HUMAN BEINGS TO LIVE...HMM.....WHAT IS IT CALLED?....OXYGEN? WELL, SERIOUSLY, ITS MIXED WITH OTHER NATURAL GASES.

Natural gas consists primarily of methane and other hydrocarbon gases. Hydrocarbons are organic compounds composed only of the elements carbon and hydrogen. The hydrocarbons in natural gas are called saturated hydrocarbons because they contain hydrogen and carbon bound together by single bonds. Methane is the simplest saturated hydrocarbon.

Could be Liquid Gas. Need more info.

Scuba is an acronym for \nSelf \nContained \nUnderwater \nBreathing \nApparatus\n\nYou need an air tank with a regulator.  You should have some device for monitoring your air supply, normally just a wrist-watch with a timer, telling you how much time you have left (estimated, based upon average consumption).  If you're doing something strenuous down there, you'll burn through the oxygen more quickly.\n\nYou'll want swim-fins and goggles, and depending on the water temp, a full wetsuit to keep warm.

not sure, i think its some kind of gas?

nitrogen, probably helium and hydrogen too.

Pure chlorine gas in a pressure tank suitable for laboratory experimentation purposes cost about $ 0.13 to $1.00 per 100 grams depending upon purity.\n\nWater treatment facilities typically use chlorine in 150-lb cylinders or one-ton containers. Some large systems use 90-ton railroad tank cars.  A one ton container costs about $420.00 in 1999.  It would be more expensive today.

What is a sealing dive?

Water has dissolved gases in it, namely oxygen.  However, oxygen, which is non-polar, doesn't particularily like being dissolved in polar water, so it will readily come out of solution in the form of bubbles if it's allowed to sit there for a while.

It's really not a matter of distance from the sun, it is a matter of space being a vacuum.  The other issue is that "air" is not normally present or contained in a spacecraft.  Most spacecraft storing gasses contain hydrazine for propulsion.  If you are talking about a manned spacecraft such as the ISS then you would be talking about liquid oxygen.  If the oxygen tank ruptured pressure would go to zero, the liquid would instantly boil and the resultant gas would dissipate.

I'd say physics rather than chemistry.  When you squeeze a bottle full of water containing a gas-filled "diver", the water is not compressed.  Only the gas in the diver compresses causing the diver to displace less water.  The cartesian diver is carefully made to be just barely buoyant, so when compressed its reduced displacement causes it to sink.

very deep diving with argon , helium oxygen mixtures,very dangerous

SCUBA is an acronym for "Self-Contained Underwater Breathing Apparatus".  Although there were earlier limited versions of a system to supply air to divers, modern day SCUBA systems are generally credited as follows:\nIn 1943, Frenchmen, Emile Gagnan and Jacques Cousteau invented the demand regulator, which adjusted the air pressure automatically, supplying air as the diver needed it. Gagnan had started design work on a similar regulator for automobile research, when cooking oil was used to replace gasoline during the war. Gagnan designed a new regulator to work with the cooking oil fuel. \n\nTogether, Gagnan and Cousteau further improved the designs of diving equipment. Their regulator was connected to three cylinders, each holding 2,500 psi of air. The complete equipment, or autonomous diving suit with the pressure regulator, was called the "Aqua-lung".  \n\nThe "Aqua-lung" is the basis for modern equipment used today, most historians refer to Gagnan and Cousteau as the fathers of modern scuba diving gear.

Hi,, hydrogen, oxygen, and nitrogen... \n\n good luck.....
