How the El Niño event affected the weather, food production, water supply, or human health? El Niño was responsible for the following events in 2015:

16 tropical cyclones in the central Pacific hurricane basin

three category 4 hurricanes occurred at the same time

emergency water rationed in St. Lucia and San Juan

65 percent of Antigua's farmers went out of business

northern, central, and southeastern Ethiopian highlands received 50–90 percent of their normal rainfal.

EL Niño  had hurricanes and so many damages in nature. :)

Explanation:

it creates warm weather, there is low pressure towards canada

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.
