10 points
carbon monoxide
carbon dioxide
lead
sulfur oxides
particulates (also known as hydrocarbons "HC")
Which of the following pollutants is also known as soot (carbon that is left over after burning) despite the fact that it is the small size of these and other suspended solids and liquids that allow them to get past our respiratory defenses? *
10 points
carbon monoxide
carbon dioxide
lead
sulfur oxides

A vapor recovery nozzle is an air pollution control device placed on gasoline pumps that prevents fumes from entering the atmosphere. Which of the following pollutants does this reduce? *
10 points
carbon monoxide (CO)
carbon dioxide (CO2)
lead (Pb)
volatile organic compounds (VOC's)
particulates
nitrogen oxides (NOx)
sulfur oxides (SOx)
Burning diesel and _______________ produces sulfur oxides and particulates. *
10 points
gasoline
natural gas
methane
coal
When this fuel is burned it releases a number of airborne toxins and pollutants including mercury, lead, sulfur dioxide, nitrogen oxides, particulates, various other heavy metals and the waste contributes far more radiation to the environment than nuclear power stations. The radioactivity comes from the trace amounts of uranium and thorium contained in this fuel. In addition to producing more carbon dioxide than any other fuel, the burning of this fuel produces fly ash, a material in which the uranium and thorium are much more concentrated. It also causes gray industrial smog. What is this resource that the industry calls "clean ________?" *
10 points
coal
oil
natural gas
gasoline
diesel
biodiesel
synfuels
A car engine produces CO, NOx and hydrocarbons. Therefore, these are considered ___________ pollutants. *
10 points
Primary
Secondary
Tertiary
A car engine produces CO, NOx and hydrocarbons. The catalytic converter changes to CO2, and N2 gas and O2 gas and water vapor. Therefore, the exhaust products after the converter are considered _____________ pollutants. *

Secondary
Tertiary
When nitrogen, carbon or sulfur hit air they become oxidized. Then if they bump into a cloud or any water vapor they become acidic. Therefore, atmospheric nitric acid, sulfuric acid and carbonic acid are considered _____________ pollutants. *
10 points

Secondary
Tertiary
This secondary pollutant is a problem in the troposphere but is needed in the stratosphere and tropopause for life to thrive on land and the upper layer of the ocean *
10 points
particulates
nitrogen oxides
sulfur oxides
ozone (O3)

Answer 1

Answer:

*1st =The substances that are regulated under the CAA include the six criteria pollutants that were originally regulated under the CAA of 1963 (sulfur dioxide, nitrogen oxides, carbon monoxide, lead, ozone, and particulate matter)

*2nd=carbon monoxide

*3rd=lead

*4th=coal

*5th =crude oil /petroleum

*6th=primary

*7th=primary

Explanation:

2nd =If not enough air/oxygen is available, coal will only 'half' burn to form the deadly odourless, colourless and toxic gas carbon monoxide

3rd=lead" (and any subsequent words) was ignored because we limit queries to 32 words.
