Oxygen oxidizes it and keeps it alive. Prolonged use (weeks at a time) leads to depleted respiratory drive when discontinued.
oxygen is an example of a pure substance because a pure substance is made up of one kind of matter and it cannot be broken down into smaller parts.
Mixture, because it is mixed with all sorts of chemicals, such as smog, and or pollen.Mixture is NOT a pure substance, because to be a pure substance, it can't be mixed with anything.
carbon, nitrogen and oxygen
Pure oxygen is a gas at 25 C, regardless of the pressure.
Yes. The air is 21% oxygen which is what humans run on. It is 79% nitrogen which we filter out. I learned this today in Health class.
It is filled with air, as prolonged exposure to pure oxygen is harmful to humans.
No, breathing pure nitrogen can be dangerous and even deadly because it can displace oxygen in the air, leading to suffocation.
Humans cannot breathe a combination of pure oxygen and hydrogen. Oxygen is necessary for respiration, but hydrogen is highly flammable and not suitable for breathing. Mixing the two gases is dangerous and can create a potential explosion hazard.
Potentially. While helium itself is inert and thus non-toxic, like any gas it can push oxygen out of the way. Breathing pure helium means you are not breathing oxygen. Without oxygen you can die in minutes.
Oxygen is an element and a pure substance.
No, humans cannot breathe nitrogen safely as it does not provide the necessary oxygen for respiration. Breathing pure nitrogen can lead to asphyxiation and suffocation.
No.
No, pure water is not poisonous to humans.
the snake is only deadly to fish, but not to humans. it will take allot of bites to in pulse venom to interact to humans ( like one billion bites to be deadly) and is less than one percent deadly to humans.
Canisters of pure oxygen can be purchased from chemical supply companies. You can also produce pure oxygen through electrolysis of water into hydrogen and oxygen.
Pure oxygen can be breathed. Pure oxygen is often given to patients in hospital that have low O2 saturation.
