Is oxygen always omnipresent on Earth?
Oxygen is not omnipresent on Earth; it makes up about 21% of the Earth's atmosphere. It is produced through processes like photosynthesis by plants and organisms in the oceans. Without these processes, the levels of oxygen on Earth would gradually decline.
How much oxygen in the air percentage?
Oxygen makes up about 21% of the Earth's atmosphere.
How much of earth's oxygen comes from algae?
About 50-80% of the Earth's oxygen comes from algae, with the majority being produced by phytoplankton in the oceans. Algae are vital for oxygen production through photosynthesis, which converts carbon dioxide into oxygen as a byproduct.
Why is there so much oxygen?
Oxygen makes up about 21% of Earth's atmosphere due to its production by photosynthesis in plants and algae. This high concentration of oxygen allows for the respiration and survival of many aerobic organisms on Earth.
What is always present in the atomosphere?
Oxygen is a gas that is always present in Earth's atmosphere. It makes up about 21% of the air we breathe and is essential for sustaining life.
Why is oxygen always a gas on earth?
The boiling point of oxygen is -183 degrees Celsius. Because it is this low, oxygen will always be a gas at room temperature.

What is oxidation state of oxygen in alkaline earth metal oxides?
The oxidation state of oxygen in alkaline earth metal oxides is -2. Alkaline earth metals always have a +2 oxidation state, which means oxygen has to have a -2 oxidation state to balance the charges in the compound.
