carbon dioxide

Photosynthesis carries out by plants, algae, and bacteria.

Some references include other gases on this list, such as krypton (less abundant than helium, but more than hydrogen), xenon (less abundant than hydrogen), nitrogen dioxide (less abundant than ozone), and iodine (less abundant than ozone).

Pure oxygen can be deadly. Our blood has evolved to capture the oxygen we breathe in and bind it safely to the transport molecule called haemoglobin. The result is that free oxygen binds to the surface proteins of the lungs, interferes with the operation of the central nervous system and also attacks the retina.

Air is mostly gas It’s a mixture of different gases. The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.

Regular air is made up of 78% nitrogen, 21% oxygen, and 1% other gases. Oxygen concentrators are usually capable of delivering 90 to 95 percent pure oxygen. They deliver air in a continuous or intermittent flow.

So if it’s not mostly oxygen in the air, what are we breathing right now? Mostly nitrogen and a combination of other gases and particles. On average, outdoor air only contains about 18-20% oxygen.

Air is a mixture of gases, consisting primarily of nitrogen (78 %), oxygen (21 %) and the inert gas argon (0.9 %). The remaining 0.1 % is made up mostly of carbon dioxide and the inert gases neon, helium, krypton and xenon.

How fish breathe. Unlike land animals, which have lungs to take in oxygen from the air, fish have gills to breathe in the oxygen contained in water. The water enters the mouth and passes through the feathery filaments of the fish’s gills, which are rich in blood.

Zero ( Dry ) Air The main difference between Atmospheric Air and Zero air is that Zero Air contains much lesser impurity contents of water vapor and Hydrocarbons than Atmospheric air. Zero Air is produced by mixing of Pure Nitrogen and Pure Oxygen in a controlled quantity composition and under controlled atmosphere.

Despite popular opinion, oxygen is not flammable. A flammable substance is one that burns. Though oxygen does not burn, it is an oxidizer, which means it supports the process of combustion. So if you already have a fuel and a fire, adding oxygen will feed the flames.

Compressed air is made of the same air you breathe in and out, but that air is compressed into a smaller size and kept under pressure. Atmospheric air and compressed air are both made up of: 78% Nitrogen. 20-21% Oxygen.

Zero Air is air which has had hydrocarbons removed via a process of oxidative catalysis to ensure it only contains less than 0.1 parts per million (PPM) of total hydrocarbons.

Compressed Oxygen Gas The air we breathe at standard atmospheric conditions contains 21% oxygen and 79% nitrogen (with some trace gases). However, compressed oxygen gas is 99.5% pure oxygen.

Synthetic Air is a mixture of Nitrogen and Oxygen. As this product is produced by controlled, homogenized mixing and because of restricted impurities Synthetic Air is used as ZERO GAS in the running and calibration of test equipment for environmental monitoring.

Because of its purity, synthetic air is used as a zero gas in the running and calibration of environmental monitoring and test equipment. In fact, it is used as a balance gas in many calibration mixtures. It is also used as an oxidiser for flame ionisation detectors in laboratory research and development.
