we breath oxygen,nitrogen,and carbon dioxide. give their chemical formulas and why they take up a lot of space

O2, N2 and CO2.\n\nDon't understand the last part

Plants.\n\nThey breathe in CO2 and breathe out Oxygen

Normal air is composed of about 78% nitrogen, 21% oxygen, .93% argon, and around .03-.05% carbon dioxide, among other gases.\n\nGood luck!

Yes.  There is a very small amount of matter that enters the atmosphere from space (meteorites), but essentially it is all just being recycled. Some atoms of oxygen you breathe in may have been breathed by a dinosaur, or one of the pharoahs!

Nitrogen by far. it is approximately 78% of what we are breathing

1)   O::C::O  for CO2 because there are total 4 valence electrons in outermost orbit of carbon so it will share 2 with each oxygen and it has 3 resonance structures\n\n2)  H . . C three electrons shared from carbon and nitrogen N\nie on one side one electron sharing by hydrogen and carbon and on other side 3-3 electrons shared by both carbon and nitrogen\n\ni hope it helps you out

carbon dioxide or CO2, it's basically what you breathe out
377149
Nitrogen (N2) 78.084 % by volume\nOxygen(O2)20.9476 % by volume\nArgon(Ar)0.934 % by volume\nCarbon Dioxide(CO2)0.0314 % by volume

Carbon combines with oxygen to form carbon dioxide and carbon monoxide. Carbon combines with water and oxygen to form carbohydrates. It does this because there is an energy advantage to do this; the end state is a lower energy state than the initial state.

C6H12O6 is the chemical formula for Glucose (I think, I can't totally remember), and O2 is oxygen. It works as enzymes in our digestive systems breaks down the glucose and it reacts with the oxygen to create C02, H2O and Energy, which is used in respiration

They are attracted to the carbon dioxide we breathe out.

Any time you have carbon, hydrogen, and oxygen going through a chemical reaction they produce carbon dioxide (CO2) and water(H2O) \nSome are: C3H8(g) + 5O2(g) -> 3CO2(g) + H2O(g) AND\nC2H5OH + 3O2 -> 2CO2 + 3H2O\nTry to think of the last one on your own. Hope that helped.

it is because the air u breath and relases has carbon in it n carbon is contigeous.

Oxygen is the gas on which human respiration is dependant. There is a relative abundance of this gas in our atmosphere. Plants (which arrived on Earth before animals) were responsible for "polluting" the primeval atmosphere with this highly reactive gas (incidentally the same gas which forms ozone and screens us from deadly high energy radiation from the sun).\n\nI'll quickly run through the rest of the planets: -\n\n1. Mercury.\nHelium atmosphere which is almost nonexistent. Surface  temperatures vary between 350C (day) and minus 170C (night).\nVerdict: - instant death.\n\n2. Venus.\nAtmosphere has large quantities of sulphur dioxide (which smells like rotten eggs or a really bad fart!) and a constant rain of sulphuric acid. Pressure 90 times greater than the Earth's. Temperature of about 500C. Suspected that this is the effect of runaway global warming (heat trapped by carbon dioxide).\nVerdict: - Instant nasty death. The closest physical approximation to Hell.\n\n3. Earth.\nMmmmm. Nice.\n\n4. Mars.\nAtmosphere of mainly carbon dioxide. Atmospheric density fluctuates, but is never enough for liquid water to form in appreciable amounts. Mean surface temperature about minus 27C.\nVerdict: - Temperature and gravity are within tolerances for human life, but needs an oxygen and water transplant. No go (for the present).\n\n5., 6., 7., and 8. Jupiter, Saturn, Uranus and Neptune.\nThese are all termed "gas giants". They all have cores, but at depths within their atmospheres such that surface pressure is enormous. Temperatures of between minus 150C (Jupiter) and minus 220C (Neptune).\nVerdict: - All non-starters.\nAs a piece of trivia, Saturn is the only planet which is less dense than water, which means that if you could find a big enough basin of water, it would float!\n\nAnd finally (phew!) 9. Pluto.\nSmaller than the moon. No atmosphere. Surface temperature minus 230C.\nVerdict: - Waste of time and space. Not even worth the term "planet". There are bigger moons than this! Ours for a start!\n\nThe combination of a planet's density and size affect its gravitational attraction. If Earth were denser or larger, its gravitational attraction would increase (ie// you'd weigh more).\nMercury is about the size and density of the moon, so you could probably jump about 10-20 feet in the air quite easily. Mars is less dense but larger than Mercury, and has comparable gravity. Venus is about the same as Earth. Jupiter isn't dense, but could hold about 1,000 Earths, so its gravity is too high for us. The other gas giants, for all their size, are appreciably less dense than Earth, and have gravities not much greater than Earth. And Pluto's so small and insignificant that I reckon if you jumped you could possibly end up in orbit around it.\n\nEarth is the ONLY place in the entire Universe that we know of which has conditions which can sustain life of any sort. If we play a part in altering the atmosphere on this planet the Earth will still exist.It just might not be suitable for life.\n\nFurther answer to your additional response bit: -\n\nIf an astronaut removed his helmet on any planet except Earth he would die almost instantly.

From the name I'd say hydrogen, carbon, oxygen and nitrogen
639958
None that we know of. On earth, there is the right mixture of oxygen, nitrogen, carbon, and other gases that is conductive to our breathing. Mars has different gas mixture which makes our lungs unable to work properly.

heres an easy one..its nitrogen 79.1%next is oxygen and then 0.03 %is carbondioxide.
