[amp_mcq option1=”NO” option2=”CO” option3=”SO2″ option4=”Soot” correct=”option1″]<\/p>\n
The correct answer is A. NO.<\/p>\n
NOx (nitrogen oxides) are the major pollutants from automobile exhaust. They are formed when the nitrogen and oxygen in the air react at high temperatures in the engine. NOx can cause a variety of health problems, including respiratory problems, heart disease, and cancer. They can also contribute to smog and acid rain.<\/p>\n
CO (carbon monoxide) is a colorless, odorless gas that is also produced by automobile exhaust. It is a major cause of accidental death, as it can cause people to lose consciousness and suffocate. CO can also cause heart problems and other health problems.<\/p>\n
SO2 (sulfur dioxide) is a gas that is produced by burning coal and other fossil fuels. It can cause respiratory problems, heart disease, and cancer. It can also contribute to acid rain.<\/p>\n
Soot is a fine black powder that is produced by incomplete combustion of fuel. It can cause respiratory problems and other health problems. It can also contribute to smog.<\/p>\n
In conclusion, the major pollutant from automobile exhaust is NOx. It is a colorless, odorless gas that can cause a variety of health problems, including respiratory problems, heart disease, and cancer. It can also contribute to smog and acid rain.<\/p>\n","protected":false},"excerpt":{"rendered":"
