Answer:
6.25 moles of N₂ is produced, and 18.8 moles of Cu and H₂O is produced.
Explanation:
We are given the chemical equation:

And we want to determine the amount of products produced when 12.5 moles of NH₃ is reacted with excess CuO.
Compute using stoichiometry. From the equation, we can see the following stoichiometric ratios:
- The ratio between NH₃ and N₂ is 2:1. (i.e. One mole of N₂ is produced from every two moles of NH₃.)
- The ratio between NH₃ and Cu is 2:3.
- The ratio between NH₃ and H₂O is 2:3. (i.e. Three moles of H₂O or Cu is produced frome every two moles of NH₃.)
Dimensional Analysis:
- The amount of N₂ produced:

- The amount of Cu produced:

- And the amount of H₂O produced:

In conclusion, 6.25 moles of N₂ is produced, and 18.8 moles of Cu and H₂O is produced.
Adding oxygen will cause the equation of
CO-Hemogoblin + O2= Hemogoblin = Oxyhemogoblin
to the right. This is because the increase in pressure leads to more on the left side, and as such a balance needs to be maintained so the equation shifts to the right.
Answer: 60 grams
Explanation: (60 ml)*(1g/ml) = 60g
Answer: Larger molecules have stronger London forces.
Explanation:
Pentane therefore has a stronger force than butane.
