When hydrogen and oxygen are mixed they form water then why exist in gaseous form?

very high temperature is needed to combine hydrogen and oxygen. at that temperature, water exists in gaseous form Oxygen exists as a gas in our atmosphere, because there isn't very much hydrogen in the atmosphere. If the Earth's atmosphere contained a substantial amount of hydrogen mixed with the oxygen, it would be an explosive mixture. Any spark would set it off. They the oxygen and hydrogen would combine to form water, and we would be left without enough oxygen to breathe.

Will there be oxygen in space if you plant a tree there?

Interesting question. The Oxygen must come from somewhere. On Earth a plant gets oxygen from 2 sources. Water and/or the atmosphere. It does not just make it up, simply transforms it from one form to another. A plant takes in Carbon Dioxide (CO2) and releases the Oxygen (O2) into the atmosphere. If there were some form of atmosphere/light/water to sustain the plants life then they will automatically produce a more oxygen rich atmosphere. As for the moon: It doesn't really have enough gravitational pull to sustain an atmosphere like that. Maybe Mars where the Atmosphere is 95% Carbon Dioxide and quite possibly large frozen lakes of ice.
