Experimental Techniques and analysis of Air
Transcript of Experimental Techniques and analysis of Air
used in common household cleaning products.
can be used to calibrate some thermometers.
it can be used to produce hydrogen bombs.
Can be used to make water.
Can be used to make Hydrochloric acid. Uses of Oxygen Oxygen gas may be used to kill bacteria that causes gangrene, because it is poisonous to them.
Near pure oxygen is used in space suits so that astronauts can breath. Scuba tanks also contain oxygen, although it usually mixed with regular air.
Rockets use liquid oxygen to burn fuel
Most commercially produced oxygen is used to convert iron ore into steel. Uses of Noble gases Helium: is used in balloons and airships
Neon: Used in glowing signs
Argon: Lightbulbs are filled with argon, or else the filament inside would react with oxygen.
Krypton: used in laser eye surgeries, krypton laser can also be used to remove unwanted birthmarks.
Xenon:Used in flash lamps
Radon:was used in medical treatments, however the hazards outweighed the benefits so that was stopped. What gases pollute the air Carbon dioxide
Methane Carbon monoxide Carbon monoxide, CO is formed when combustion of carbon based materials take placed and there is not enough oxygen to create carbon dioxide.
inhalation of carbon monoxide, may cause carbon monoxide poisoning, the carbon monoxide will be picked up by hemoglobin, this will block the oxygen from being carried around the body, this results in death by "oxygen starvation". Acid rain sulfur dioxide and nitrogen oxides dissolve in rain formin acid rain. ways to reduce air pollution Conserve energy - turn off appliances and lights when you leave the room.
Recycle paper, plastic, glass bottles, cardboard, and aluminum cans.
Plant trees in locations around your home to provide shade in the summer, but to allow light in the winter.
Buy green electricity-produced by low-or even zero-pollution facilities.
Connect your outdoor lights to a timer or use solar lighting. Test for oxygen Light a splint then blow it out leaving only some embers, put the splint in the container were you want to test for oxygen, if the splint lights up again then oxygen is present, because, only oxygen gas will support burning.It is the only gas that will relight a glowing splint. Test for Hydrogen light a splint, place the splint in the container you want to test for hydrogen, and listen for a "squeaky pop" that tells you there is Hydrogen present. Test for Carbon dioxide In chemistry, lime water can be used to detect the presence of carbon dioxide because lime water reacts with carbon dioxide, Carbon dioxide will turn lime water 'milky' or cloudy.
