Question

6Li + N2 2Li3N

If 12 mol of lithium were reacted with excess nitrogen gas, how many moles of lithium nitride would be produced?

4.0 mol
6.0 mol
12 mol
36 mol

Answer 1

The answer would be B ur looking for the total reaction and the time that it takes for it I be produced Wich would be 6.0

Answer 2

Answer : The correct option is, 4.0 mole

Explanation : Given,

Moles of lithium = 12 mole

The given balanced chemical reaction is:

`6Li+N_2\rightarrow 2Li_3N`

By the stoichiometry we can say that, 6 moles of Li react with 1 mole of
`N_2` to give 2 moles of
`Li_3N`

As, 6 moles of lithium react to give 2 moles of lithium nitride

So, 12 moles of lithium react to give
`(12)/(6)* 2=4` moles of lithium nitride

Therefore, the number of moles of lithium nitride produced will be 4.0 mole.
