There is no oxygen on Venus as the atmosphere is almost
full of carbon dioxide.
There is little free oxygen on Venus, although almost all of the water there apparently broke down into hydrogen and oxygen. The majority of the planetary oxygen is bound as carbon dioxide and sulfur dioxide in the atmosphere, and as oxides on the surface.There is apparently no plant life on Venus, and plants are what supply the atmospheric oxygen on Earth.
Venus might have about 38% of oxygen but the atmosphere is thin on Venus
no, there is no oxygen on venus
Yes, you would need to bring an oxygen mask to Venus. Venus has an extremely thick atmosphere consisting mainly of carbon dioxide, with very little oxygen. Without an oxygen mask, it would be impossible to breathe on Venus.
Venus does not have the correct requirements that we need in order to live on it. Venus has no Oxygen so survival would be minimal and without any trees/crops we'd also die of starvation.
Venus has no molecular oxygen.
If by Oxygen you mean pure Oxygen molecules, then no, only possible trace amounts. However, there is massive amounts of Carbon Dioxide (95% of Venus's atmosphere) which can be fairly easily be converted into oxygen.
There is air, of course, surrounding Earth, because it was placed there, but any of the elements that combine to make an atmosphere have dissolved or dissipated out into the vastness of space.
3.5 percent
Venus
No, because plants need oxygen to live and there isn't oxygen inside the dirt in Venus. As for the outside with the air, maybe.
If a potassium chlorate sample is contaminated with KCl, the experimental percent oxygen would be lower than the theoretical percent oxygen. This is because KCl does not contain oxygen, so the contamination would dilute the amount of oxygen produced during the decomposition of potassium chlorate.
