Answer:
A: 10 moles of water are required.
B: 27 moles of Câ‚‚Hâ‚„ Â are used.
Explanation:
A:
Given data:
Moles of water used = ?
Moles of Câ‚‚Hâ‚…OH formed = 10 mol
Solution:
Chemical equation:
C₂H₄ + H₂O   →    C₂H₅OH
Now we will compare the moles of water with Câ‚‚Hâ‚…OH from balance chemical equation:
          Câ‚‚Hâ‚…OH       :      Hâ‚‚O Â
             1          :       1
            10          :     10
10 moles of water are required.
B)
Given data:
Moles of Câ‚‚Hâ‚„ used = ?
Moles of Câ‚‚Hâ‚…OH formed = 27 mol
Solution:
Chemical equation:
C₂H₄ + H₂O   →    C₂H₅OH
Now we will compare the moles of Câ‚‚Hâ‚„ Â with Câ‚‚Hâ‚…OH from balance chemical equation:
          Câ‚‚Hâ‚…OH     :      Câ‚‚Hâ‚„ Â
             1         :       1
             27        :       27
27 moles of Câ‚‚Hâ‚„ Â are used.
