Oxygen is naturally found in the Earth's atmosphere, making up about 21% of the air we breathe. It can also be found in water molecules (H2O) and in the cells of living organisms where it plays a vital role in cellular respiration. Additionally, oxygen is produced through photosynthesis by plants and certain types of bacteria.
To find the percent of oxygen by mass in a compound, you need to know the molar mass of the compound and the molar mass of oxygen. Divide the molar mass of oxygen by the molar mass of the compound and multiply by 100 to get the percentage.
To find the percent composition of oxygen in Na2O, find the total molar mass of the compound. Then, divide the molar mass of oxygen by the molar mass of the compound, and multiply by 100% to get the percent oxygen.
You can find information about oxygen in science textbooks, online encyclopedias, scientific journals, and reputable websites from scientific organizations. It is also common to find information about oxygen in chemistry and biology resources.
Oxygen attaches to heme through coordination bonding. The iron atom at the center of heme forms a reversible bond with oxygen, creating oxyhemoglobin. This interaction is crucial for oxygen transport in the blood.
Oxygen-depleted blood can be found in the veins, as it has already delivered oxygen to the body's tissues and is returning to the heart to be reoxygenated in the lungs.
One can find medical oxygen solutions from the following sources: Health Oxygen, Portable Oxygen, Oxygen Solutions, Alternative Oxygen Solutions, to name a few.

Oxygen is everywhere in the atmosphere. The animal simply has to breathe.
Canisters of pure oxygen can be purchased from chemical supply companies. You can also produce pure oxygen through electrolysis of water into hydrogen and oxygen.
