The following statements were stated by a politician who was paid by the nuclear energy lobby in a debate in favor of nuclear energy: a. Nuclear energy doesn’t produce a byproduct because the atoms disappear.

b. Nuclear energy produces no polluting gas in its reaction.

c. Nuclear energy does not contribute to global warming.

d. Nuclear energy has low mining and transportation effects on environment.

Which statement is false and should not be used to argue in favor of nuclear energy?

A) Statement A

B) Statement C

C) Statement D

D) Statement B

d

Explanation:

the best state ment is d lol

n2(g) + 3h2-> 2nh3(g)   this is the balanced equation

note the mole ratio between n2, h2 and nh3.   it is 1 : 3 : 2   this will be important.

moles n2 present = 28.0 g n2 x 1 mole n2/28 g = 1 mole n2 present

moles h2 present = 25.0 g h2 x 1 mole h2/2 g = 12.5 moles h2 present

based on mole ratio, n2 is limiting in this situation because there is more than enough h2 but not enough n2.

moles nh3 that can be produced = 1 mole n2 x 2 moles nh3/mole n2 = 2 moles nh3 can be produced

grams of nh3 that can be produced = 2 moles nh3 x 17 g/mole = 34 grams of nh3 can be produced

note:   the key to this problem is recognizing that n2 is limiting, and therefore limits how much nh3 can be produced.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
