After the nuclear plant in Japan failed in 2011, nuclear waste was released into the surrounding groundwater and ocean. How did this impact the surrounding human population? A)The nuclear waste leaked into the ground and stayed in that location, affecting only humans who farmed or otherwise disturbed the soil.

B)The nuclear waste was not radioactive; therefore it did not affect the human population

C) The nuclear waste leaked into groundwater, and exposed humans to radiation that could potentially cause cancer.

D)The nuclear waste leaked into the sea and affected those exposed to seawater, but did not affect those on land

c

Explanation:

the others one not work bc osmething like that would effect any human

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.
