The energy required for the chemical reaction of 21.7 grams of nitrogen to produce ammonia is how many kilojoules? If you put something that isn't the answer I will report you.

Explanation:

Hello!

In this case, since the formation of ammonia by starting with nitrogen and therefore hydrogen is:

Which has an energy of reaction of:

We can compute the energy required for this reaction by first computing the moles of ammonia yielded by 21.7 grams of nitrogen (28.02 g/mol) via stoichiometry:

Thus, the energy turns out:
