What does nitrogen oxides and sulfur oxides make?
What does nitrogen oxides and sulfur oxides make?
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
What is the major source of oxides of Sulphur and nitrogen in the atmosphere?
Volcanoes are a natural source of sulfur oxides in the atmosphere, but 99% of the sulfur dioxide in the atmosphere comes from human activity, such as burning coal, oil, and gas to make electricity and heat. When coal and oil burn, the sulfur in them combines with oxygen in the air to make sulfur oxides.
What are the oxide of nitrogen?
Oxides of nitrogen are a mixture of gases that are composed of nitrogen and oxygen. Two of the most toxicologically significant compounds are nitric oxide (NO) and nitrogen dioxide (NO2). Other gases belonging to this group are nitrogen monoxide (or nitrous oxide, N2O), and nitrogen pentoxide (NO5).
What are the oxide of Sulphur and nitrogen that causes acid rain?
Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.
Why is SO2 bad?
Sulfur dioxide, associated SOx, and secondary pollutants can contribute to respiratory illness by making breathing more difficult, especially for children, the elderly, and those with pre-existing conditions. Longer exposures can aggravate existing heart and lung conditions, as well.
What does oxides of nitrogen cause?
Environmental and health effects of nitrogen oxides Elevated levels of nitrogen dioxide can cause damage to the human respiratory tract and increase a person’s vulnerability to, and the severity of, respiratory infections and asthma. Long-term exposure to high levels of nitrogen dioxide can cause chronic lung disease.
What is the source of oxides of nitrogen Mcq?
Sources. Nitrogen oxides are produced in combustion processes, partly from nitrogen compounds in the fuel, but mostly by direct combination of atmospheric oxygen and nitrogen in flames.
Is nitrate a nitrogen oxide?
The inorganic anions nitrite (NO2−) and nitrate (NO3−) are usually viewed as inert end products of nitric oxide (NO) metabolism or unwanted residues in the food chain. Recent studies show that nitrate and nitrite are physiologically recycled in blood and tissue to form NO and other bioactive nitrogen oxides.
How are the oxides of nitrogen formed?
Nitrogen oxides are produced in combustion processes, partly from nitrogen compounds in the fuel, but mostly by direct combination of atmospheric oxygen and nitrogen in flames. Nitrogen oxides are produced naturally by lightning, and also, to a small extent, by microbial processes in soils.
How do oxides of sulphur and nitrogen released in the air pollute the environment?
Oxides of sulphur and nitrogen are responsible for many natural phenomena. Similarly, oxides of sulphur such as sulphur dioxide enter the atmosphere by natural processes such as volcanic eruptions. Thus, it is causing an imbalance in the earth’s atmosphere and exerting detrimental effects.
How does sulfur dioxide affect your health?
Sulfur dioxide side effects to be aware of include tightness in your chest and throat, wheezing and coughing, reports an article in the March 2017 issue of the Journal of Asthma and Allergy. For some people, especially those with asthma, the side effects can turn into a life-threatening anaphylaxis reaction.
What are the health effects of nitrogen oxide?
Breathing nitrogen oxides can cause: Irritation of the respiratory system, eyes, and skin. Aggravation of respiratory diseases, particularly asthma. Coughing and choking. Nausea. Headache. Abdominal pain.
How does sulfur dioxide affect the environment?
Environmental effects. When sulfur dioxide combines with water and air, it forms sulfuric acid, which is the main component of acid rain. Acid rain can: cause deforestation. acidify waterways to the detriment of aquatic life. corrode building materials and paints.
How are oxides of sulfur and nitrogen released into the air?
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
