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 : 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 \(\frac{12}{6}\times 2=4\) moles of lithium nitride

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