Determine whether each of the following statements about sulfur oxide and/or nitrogen oxide pollution is true or false.

(a) most sulfur oxides formed during combustion come from sulfur in the air.
(b) a flue gas scrubber removes so2 pollution in a coal-fired power plant by using lime to convert the so2 into alcohols.
(c) the largest source of nitrogen oxide pollution is non-road vehicles.

a) False

b) False

c) True

Explanation:

a) Most sulfur oxides formed during combustion come from sulfur in the air: The sulfur burns in presence of oxygen to produce sulfur oxides, the source of sulfur is anthropogenic activities (Human activities).

So the given statement is false.

b) A flue gas scrubber removes SO2 pollution in a coal-fired power plant by using lime to convert the SO2 into alcohols:

False

The lime reacts with sulfur dioxide to give carbon dioxide and calcium sulfite.

c) True

c)
