)
Since the mole ratio of
N
2
to
H
2
is
1
:
3
, then for every mole of nitrogen, we would need three moles of hydrogen.
Explanation:
To correct chemical formula for ammonium carbonate is the first option
2 - PE of products-PE of reactants.
You are trying to calculate the energy change that occurred from the start of the reaction (the reactants going in) to the end of the reaction (the products coming out). Therefore if there is more energy at the end, you will get a positive result from subtracting the PE of the reactants, and vice versa.
