Question 7

Primary pollutants

Answer 7

Are harmful chemicals emitted directly into the air from natural processes and human activities

Question 8

Secondary pollutants

Answer 8

Some primary pollutants react with the basic components of air to form new harmful chemicals

Question 9

Different variations of carbon and oxygen

Question 10

Carbon monoxide

Answer 10

Is a colorless, odorless, and highly toxic gas that comes from ma during the incomplete combustion of carbon-containing materials

Question 11

Carbon dioxide

Answer 11

Is a colorless, odorless, has.

Question 12

Nitric oxide

Answer 12

Is a colorless gas that forms when nitrogen and oxygen gas in the air react at the high-combustion temperatures in automobile engines and coal burning plants

Question 13

Nitrogen dioxide

Answer 13

In the air, No reacts with oxygen and creates this. And is a reddish-brown gas

Question 14

Nitrogen oxides

Answer 14

Collectively, No and No2 are called this

Question 15

Nitric acid

Answer 15

Some of the NO2 reacts with water vapor in the air to form this

Question 16

Acid decomposition

Answer 16

(HNO3) and nitrate salts (NO3) complements of harmful this

Question 17

Photochemical smog

Answer 17

A mix of chemicals formed under the influence of sunlight in cities with heavy traffic

Question 18

Nitrous oxide (N2O)

Answer 18

A greenhouse gas, is emitted from fertilizers and animal wastes and is produced by burning fossil fuels

Question 19

Sulfur dioxide (SO2)

Answer 19

Is a colorless gas with an irritating odor

Question 20

Aerosols

Answer 20

Are microscopic suspended particles of sulfuric acid and suspended parts of sulfate salts that return to the Seth as a component of acid decomposition

Question 21

Answer 22

Organic compounds that exist at gases called this

Question 23

Industrial smog

Answer 23

Smog that consists mostly of sulfur dioxide, suspended droplets of sulfuric acid, and a variety of suspended solid particles

Question 24

Photochemical smog

Answer 24

A mixture of primary and secondary pollutants formed under the influence of UV radiation of the sun

Question 25

Brown-air smog

Answer 25

Also known as photochemical smog

Question 26

Photochemical oxidants

Answer 26

Collectively NO2, O3, and PANs in this chemical brew

Question 27

PANs

Answer 27

The resulting photochemical smog is a mixture of ozone, nitric acid, aldehydes, peroxyacyl nitrates, and other secondary pollutants

Question 28

Grasshopper affect

Answer 28

Occurs when volatile air pollutants are transported by evaporation and winds from tropical and temperature areas through the atmosphere to the serge polar areas, where they are deposited

Question 29

Temperature inversion

Answer 29

Under certain atmospheric conditions however a layer of warm air can temporarily lie atop a layer of cooler air nearer the ground
