It's oxygen
they need oxagen and oxagen.
oxagen
oxagen and plants
oxagen
Actually it's in Asia.I took a Diagnostic test about Mt.Everest and it said it was in Aisa.And you have to where a oxagen tube.Because the top almost touches SPACE!And space doesn't have alot of oxagen for you to breath.So if you have one on you're ok.If you don't GOOD LUCK [NOT]SURVIVEING!
everything would die because trees turn carbon dioxide in to oxagen
O% because it is not a solid planet and it has no oxagen which you probably need.
when a human gives carbon dioxide to the plants while the plants give oxagen to the humans and animals XD
yes if you mix anything with 2 hydrogen atoms and 1 oxagen atom than a reaction will take place
lack of air (oxagen) and the heat from the sun
Oxygen has 8 protons. This is determined by its atomic number, which is also 8 on the periodic table. The number of protons in an element is what defines it and distinguishes it from other elements.
The two most common gases in Earth's atmosphere are nitrogen, which makes up about 78%, and oxygen, which makes up about 21%.
