Answer:
minimum number of trays:
N = 7 trays
Explanation:
minimum number (N):
- N = ( Log ( (Xd / ( 1 - Xd )) * (( 1 - Xb ) / Xb )) ) / Log α....Fenske's Eq. binary mixture
∴ α = 2.5
∴ Xd = 0.96.......molar fraction the distillate
∴ Xb = 0.04 .........molar fraction in the bottoms
⇒ N = ( Log ( ( 0.96 / ( 1 - 0.96 ) ) * ( ( 1 - 0.04 ) / 0.04 )) ) / Log ( 2.5 )
⇒ N = 6.94 ≅ 7 trays

Answer: <em>
pH=2.25 </em></h3>
Explanation:
monochloroacetic acid also means: chloroacetic acid
pKa of monochloroacetic acid= 1.4 x 10^-3 (I believe this should have been given in the problem or perhaps in the textbook)
Formula: pH= pKa + log ( some number in M)
pH= -log (1.4 x 10^-3) + log (0.25M)= 2.85 + -0.602= 2.25
pH= 2.25

Hi, I believe this question is asking what charge Phosphorus will have when it forms an ion. If that is the case, you will see that it based on the column it is in, neutral Phosphorus has 5 valence electrons. When it becomes an ion (has 8 valence electrons), it will GAIN three electrons. Meaning, we can predict that Phosphorus will have a 3- charge when it becomes an ion.
Answer:
35.47+10.1 is 45.57, I hope that helped nc I'm new to this app and yea.
