6 Li + N2 --> 2 Li3N

How much N2 is needed to make 1.34 moles of Li3N?

0.67 moles

Explanation:

6 Li(s) + N2(g) ---> 2 Li3N(s)

The balanced reaction above shows that 6 moles of Lithium, (Li) added to 1 mole of Nitrogen gas, (N2) yields 2 moles of Lithium nitrite, (Li3N)

I.e 1 mole of N2 = 2 moles of Li3N

Since the number of N2 needed to make 1.34 moles of Li3N is unknown, it is represented by Y

So, 1 mole of N2 = 2 moles of Li3N

Y = 1.34 moles of Li3N

To get the value of Y, cross multiply

1.34 x 1 = Y x 2

1.34 = 2Y

To get the value of Y divide both sides by 2

1.34/2 = 2Y/2

0.67 = Y

Thus, 0.67 moles of N2 is needed to make 1.34 moles of Li3N.

explanation:

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
