Does air or water have more oxygen?
Air has more oxygen compared to an equal volume of water. Air is composed of approximately 21% oxygen, while water contains dissolved oxygen, but in much lower concentrations, usually around 5-8 parts per million.
Is there more oxygen in seawater or air?
There is more oxygen in seawater. Seawater contains around 5 to 10 milligrams of oxygen per liter, while the concentration of oxygen in the air is about 210 milligrams per liter. However, the total amount of oxygen in the oceans is much higher due to their vast volume.
About what fraction of air is made of oxygen?
Oxygen makes up about 21% or approximately 1/5 of the air.
What percentage of oxygen can be found in air?
78% Nitrogen 20.5% Oxygen .5% Argon 1% Others for small calculations we take percentage of oxygen in air as 21%
What is the percentage difference between inhaled and exhaled oxygen?
The percentage difference between inhaled and exhaled oxygen is around 5-10%. When we inhale, we breathe in air that contains approximately 21% oxygen, and when we exhale, the air we breathe out contains around 16-17% oxygen due to the exchange of gases that occurs in the lungs.
How much oxygen will you need for a 5 gallon aquarium?
Air bubbles will do nothing. What is needed is a filter.
What are the two gases which are present during inhaling and exhaling air?
Oxygen is the gas that we inhale during breathing, while carbon dioxide is the gas that we exhale. Oxygen is used by the body for cellular respiration, and the waste product carbon dioxide is eliminated through exhalation.
How much oxygen is needed in a 5 gallon tank?
If you are referring to Air pumped from an "aerator' Then the answer is "none". A filter is needed not an air pump.

How much oxygen nitrogen carbon dioxide is there in the air you breathe out?
Oxygen---------- 4-5 % Carbon dioxide---------- 20% Nitrogen--------- 75%
About what fraction of air is made of oxygen?
Oxygen makes up about 21% or approximately 1/5 of the air.
What are 5 examples of gases found at home?
5 examples of gases found in the normal home environment include; oxygen (air), nitrogen (most abundant element found in the air), carbon dioxide (air and the bubbles in fizzy drinks), argon in air and finally, methane if there is a gas supply, or propane or butane in fuel gas bottles. Carbon monoxide and SO2. are present in polluted air. You might have helium in a balloon.
What percentage of oxygen can be found in air?
78% Nitrogen 20.5% Oxygen .5% Argon 1% Others for small calculations we take percentage of oxygen in air as 21%
Does ocean water have higher levels of oxygen than air?
No, air contains about 21% oxygen, while ocean water contains only about 5-10 milliliters of dissolved oxygen per liter. The higher concentration of oxygen in the air makes it easier for animals to extract the oxygen they need for respiration.
Does oxygen make up 40 percent of the air?
No , it makes up 20.9% of air , almost 21%
number of atoms present in compound starch?
6 carbon, 10 hydrogen and 5 oxygen atoms
