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

4 mol  of lithium nitride would be produced

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

4 mol  of lithium nitride would be produced

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

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
