Answer:
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:
Best regards!
There isn't really a reaction going on, but they are linked by peptide bonds
