Why was there more oxygen in the past?

In the past, there was more oxygen in the atmosphere due to higher levels of photosynthesis by plants and algae, which produced oxygen as a byproduct.


Which has higher boiling point oxygen or ethanol?

Oxygen.


Why is there less oxygen at higher altitudes?

At higher altitudes, there is less oxygen because the air pressure decreases as you go higher up in the atmosphere. This means that there are fewer oxygen molecules available for breathing.


Which element has a higher electronegativity than nitrogen?

There are two elements. They are Fluorine and Oxygen


Why people feel breathless as they climb higher and higher on a mountain?

As people climb higher and higher on a mountain, the air becomes thinner, which means there is less oxygen available for the body to use. This leads to a decrease in oxygen reaching the tissues and cells, causing a person to feel breathless as the body works harder to compensate for the lower oxygen levels.


What happen when higher energy ultraviolet radiations act on the oxygen at the higher level of the atmosphere?

When higher energy ultraviolet radiations act on oxygen at higher levels of the atmosphere, they can break apart oxygen molecules (O2) into two individual oxygen atoms. These oxygen atoms can then combine with other oxygen molecules to form ozone (O3) through a series of reactions. This process is important for the formation of the ozone layer, which helps protect Earth from harmful UV radiation.


What does high oxygen in water mean?

An oxygenated water (with a higher concentration of oxygen).


Is there really less oxygen at higher elevations?

Actually, the reason there isn't less oxygen at higher elevations. The reason it is harder to breathe is because the partial pressure of oxygen is much lower at higher elevations, preventing gas exchange of oxygen with the tissues in your body.


Does chlorine or oxygen has higher boiling point?

Chlorine has a higher boiling point than oxygen. Chlorine's boiling point is -34.6 degrees Celsius, while oxygen's boiling point is -183 degrees Celsius.


How is there less oxygen in higher altitude?

At higher altitudes, there is less oxygen in the air because the air pressure decreases with elevation. This results in fewer oxygen molecules per unit volume of air. As a result, it becomes harder for humans to breathe in enough oxygen to meet their body's needs at higher altitudes.


What is the relationship of oxygen density to altitude?

Oxygen density decreases as altitude increases. This is due to the decrease in atmospheric pressure at higher altitudes, which results in a lower concentration of oxygen molecules. Therefore, the higher the altitude, the lower the oxygen density.


Why does oxygen and carbon dioxide vary with depth?

because as you go higher the oxygen grows lighter
