The predominant greenhouse gas produced by human use of fossil fuels is view available hint(s) the predominant greenhouse gas produced by human use of fossil fuels is nitrous oxide (n2o) carbon dioxide methane sulfate aerosols

carbon dioxide

Explanation:

Carbon dioxide -

The gas carbon dioxide has a molecular formula of CO₂ ,

During the burning process of the fossil fuels , carbon dioxide is resealed in numerous amount , which act as a greenhouse gas .

Greenhouse gas - Are the gases which absorbs and release radiation , and are responsible for the greenhouse effect .

The greenhouse gases are - carbon dioxide , water vapor , methane , ozone , nitrous oxide .

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.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
