Answer:

6Li + N2 ---------------> 2Li3N  

Notice that the balanced equation says that if you have 6 moles of Li you get 2 moles of Li3N??  

Well 12 moles is just double 6 moles, so wouldn't you expect 4 moles of Li3N to be formed?

Step-by-step explanation:


Answer: 4 moles of [tex]Li_3N[/tex]

Explanation:

The balanced chemical equation for the reaction is:

[tex]6Li+N_2\rightarrow 2Li_3N[/tex]

As can be seen from the chemical equation, 6 moles of lithium reacts with 1 mole of nitrogen to produce 2 moles of lithium nitride.

Given : Lithium is the limiting reagent as it limits the formation of product and nitrogen is the excess reagent as it is present in excess.

Now if 6 moles of lithium produces = 2 moles of [tex]Li_3N[/tex]

Thus 12 moles of lithium produces = [tex]\frac{2}{6}\times 12=4moles[/tex] of [tex]Li_3N[/tex]

Thus 4 moles of [tex]Li_3N[/tex]will be produced.
