The illustration depicts the formation of an ionic chemical bond between lithium and fluorine atoms. Why is the resulting compound more stable than the individual atoms?
A)
The shared electron from Lithium to fluorine provides each atom with a full
outer energy level.
B)
The shared electron from Lithium to fluorine provides each atom with an
empty outer energy level.
The transferred electron from lithium to fluorine provides each atom with a
full outer energy level
D)
The transferred electron from Lithium to fluorine provides each atom with
an empty outer energy level.

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.

give me abc and i will get it for u.
