Oxygen is not a compound, but a diatomic molecule, and carbon dioxide is a compound.In summary, air is a mixture of several gases, with the majority being nitrogen and the rest being oxygen, argon, and carbon dioxide. It is not a heterogeneous mixture, nor is it a pure substance or a...

The atmosphere in the building, as the biosphere around this planet, is a mixture of gases, mostly nitrogen and oxygen, and water vapour. There may be traces of other gases, particularly pollutants, which can be removed by filtration, absorption, or by ventilating the space. The water vapour...
The researches have shown that the most effective method of decreasing the levels of NOx is the recirculation gases mixture with the primary air or gaseous fuel, because in this case it acts on the maximum of temperature of the flame core. Thus the burning rate is reduced, which increase ...
Compared with the density of pure water (1000 kg m−3), the density of air is very small. In reality, air is never completely dry, even in a desert, which means the air is always a mixture of dry air and water vapor (moist air, Fig. 11.1). Although the water vapor content is...
Accordingly, it is not necessary to perform a pre-cooling of the refrigerant or to prepare ice water. In addition, since single substance or mixture substances of pure water, anti-odor agent, anti- bacteria agent, anti-tick agent and aromatic agent or the like can be fed into the ...
