This problem is providing information about the moles of ammonia that are consumed in excess copper(II) oxide and the produced moles of nitrogen, copper and water are required.
<h3>Chemical equation:</h3>
At first instance, we must write the balanced chemical reaction that takes place when the aforementioned reactants are reacted, in agreement to the law of conservation of mass:
<h3>Mole ratios:</h3>
Next, since 6.5 moles of ammonia, NH3, is given, it turns out possible for us to apply the following mole ratios in order to calculate the required moles of each product:
