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.

Respuesta :

Answer:

a) False

b) False

c) True

Explanation:

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.
