Many different forms are commercially available, from the supercoolant liquid nitrogen to nitrous oxide, a type of anesthetic. The gas is the lightest of the nitrogen group of chemical elements, with the atomic number seven. It is identified on the periodic table of elements by the symbol N....
aHuman activities causing global climate change are the burning of fossil fuels, which release CO2, water vapour, and SO2¬ into the atmosphere; agricultural activity, which releases CO2 from the soil; the increased use of fertilizer and animal husbandry, which adds nitrous oxide (N2O) and ...
resulting in higher yields. We now know that globally, soil contains four times as much carbon as the atmosphere or the entirety ofterrestrial vegetation. Much of that carbon has been released by conventional agriculture but can be restored using alternative methods. That awareness has l...
the methane cycle (methane is the gas linked to putrefaction), and that of nitrous oxide, the consequences of the increase of tropospheric ozone (the one close to the ground), the role of organic or mineral aerosols (dust, soot…), But one should not deduct from the fact t...
In addition, individuals use N₂O for automotive performance but this should never be used recreationally. Automotive-grade nitrous oxide contains sulfur dioxide which makes it unpleasant to inhale. This type of nitrous oxide can also harm the lungs. Whiteout and some solvents or glues also con...
A‘three-way catalytic converter’ (TWC) simultaneously removes three main compounds using reduction and oxidation reactions: Reduction of nitrogen oxides (NOx) to nitrogen – NOx may be nitrous oxide (NO) or nitrogen dioxide (NO2) gases which create smog and acid rain. ...
In most American cities, the personal automobile is the largest overall polluter, spewing millions of pounds of greenhouse gases like carbon dioxide, nitrous oxide, carbon monoxide and sulfur oxide into the atmosphere and into our lungs [source: EPA]. Eco-conscious consumers see t...

Normal urine contains chemicals called nitrates. If bacteria enter the urinary tract, nitrates can turn into different, similarly named chemicals called nitrites. Nitrites in urine may be a sign ofa urinary tract infection(UTI). UTIs are one of the most common types of infections, especially in ...
