Answer:
y = 35.06 %.
Explanation:
The reaction of fermentation is:
C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂ (1)
From the reaction (1) we have that 1 mol of C₆H₁₂O₆ produces 2 moles of C₂H₅OH, then the number of moles of C₂H₅OH is:
Now, we need to find the mass of C₂H₅OH:
Finally, the percent yield of C₂H₅OH is:
![\% = \frac{32.3 g}{92.14 g}*100 = 35.06 \%](https://tex.z-dn.net/?f=%20%5C%25%20%3D%20%5Cfrac%7B32.3%20g%7D%7B92.14%20g%7D%2A100%20%3D%2035.06%20%5C%25%20)
Therefore, the percent yield of C₂H₅OH is 35.06 %.
I hope it helps you!
Answer:
the correct answer is option C. Na
Because the atom is neutral, it has no charge. For this to happen, the number of positive and negative charges must be the same. Therefore, because there are 11 -1 charged electrons, there must also be 11 +1 charged protons
So the answer is (2)
