no it does not
no there is no oxygen on mars and no water
mars atmosphere is thinner and lacks oxygen or water
Well it has no oxygen but it has frozen water so if life existed on mars they would not be humans.
oxygen, water vapor, nitric oxide
Because there is no water,oxygen,food.
No,you need 2 hydrogen atom and 1 oxygen atom to make water,and that is why water is also known as H2O
No oxygen, no water and no food would make for a quick demise of a man on Mars.
Yes, oxygen does exist on Mars, but in much lower concentrations compared to Earth. The atmosphere on Mars is about 95% carbon dioxide, with only about 0.1% oxygen. This low oxygen level makes it difficult for humans to breathe on Mars without assistance.
no, but mars used to have fresh water, but no oxygen.
You could if you separated the hydrogen and oxygen of the water ice by electrolysis, which would probably be very impractical.
Water has been found on the surface of Mars. There are traces of oxygen, which is also a component of water, in the Martian atmosphere.
Mercury and Venus are inner planets that does not have water and oxygen. Mars might be another, but we don't know. It might have water. Now Earth....if there was no water and oxygen, I wouldn't be replying to this(except if I was alien, eh?)!
