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

4 moles of

Explanation:

The balanced chemical equation for the reaction is:

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

Thus 12 moles of lithium produces = of

Thus 4 moles of will be produced.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
