How many molecules of ammonia NH3 would be produced by the following reaction if you had 5.2 molecules of N2
N2 + H2 --> NH3

10.4 moles

Explanation:

The balanced equation below represent the production of 2 molecules of ammonia from 1 molecule of nitrogen and 3 molecules of hydrogen respectively

N2 + 3H2 --> 2NH3

Now, if 1 mole of N2 gives 2 moles of NH3

5.2 moles of N2 would give Z moles of NH3

To get the value of Z, cross multiply

Z moles x 1 = 2 moles x 5.2

Z = 10.4 moles

Thus, 5.2 molecules of N2 would yield 10.4 moles of NH3

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.

what is the question here. i think you messed up.
