Question

The equation below shows lithium reacting with nitrogen to produce lithium nitride. 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

Answer:

4 mol of lithium nitride would be produced

Step-by-step explanation:

6Li + N2 → 2Li3N

This equation means that 6 mol of lithium are reacted with 1 mol of nitrogen to make, 2 mol of lithium nitride.

So this is the rule of three to find out, how many moles of lithium nitride are been made, from 12 mol of Li.

6 Li _____ 2 Li3N

12 Li ________ (12. 2) / 6 = 4 moles

Answer 2

4 mol of lithium nitride would be produced

Step-by-step explanation:

6Li + N2 → 2Li3N

This equation means that 6 mol of lithium are reacted with 1 mol of nitrogen to make, 2 mol of lithium nitride.

So this is the rule of three to find out, how many moles of lithium nitride are been made, from 12 mol of Li.

6 Li _____ 2 Li3N

12 Li ________ (12. 2) / 6 = 4 moles
