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.

CaCO_{3}+SO_{2}--->CaSO_{3}+CO_{2}

Use the following equation to determine how many moles of C are needed to react with 0.500 mole of SO2.
Maru [420]

Answer:

The answer to your question is 1.25 moles of C

Explanation:

Reaction

                                5C  +  2SO₂   ⇒   CS₂  +  4CO

Check that the reaction is balanced

                          Reactant         Element        Product

                                5                   C                   5

                                2                    S                    2

                                4                   O                    4

Use proportions to find the moles of C needed.

                       5 moles of C -----------------  2 moles of SO₂

                       x  moles of C ----------------   0.500 moles of SO₂

                       x = (0.500 x 5) / 2

                       x = 1.25 moles of C
