Answer:
7 moles
Explanation:
Given data:
Moles of hydrogen = 7 mol
Moles of water formed = ?
Solution:
Chemical equation:
2H₂ + O₂ → 2H₂O
Now we will compare the moles of water with hydrogen from balance chemical equation:
H₂ : H₂O
2 : 2
7 : 7
So in the presence of excess oxygen and 7 moles of hydrogen seven number of moles of water produced.
Answer: NO2, NO, and O2.
