How are nitrogen oxides produced?
it is produced form animals, plants and factory.
These bacteria, through the plant, receive elemental nitrogen from the air, and use it to produce ammonia (NH3). This process is called nitrogen fixation. The ammonia can then be converted in to oxides of nitrogen and nitrogen salts, such as nitrites and nitrates, which are used by the host plant and others as nutrients.
water reacts with oxides of nitrogen to form nitric acid(HNO3) which causes acid rain. Oxides of nitrogen are formed by vehicle exhausts, and other sources of air pollutants, and when atmospheric nitrogen combines with oxygen during lightening. These oxides combine with rain drops and make rain acidic.
Acid rain is caused by emissions of sulphur dioxide and nitrogen oxides which react with the water molecules in the atmosphere to produce acids.Nitrogen oxides can be produced naturally by lightning strikes and sulphur dioxide is produced by volcanic eruptions and industrial emissions. It also can be from gases from burning coal and oil released into the air.
