Answer:

An isotope is an element that has a different amount of neutrons than its standard atomic mass. ... Subtract the number of protons from the atomic mass. This is the number of neutrons that the regular version of the atom has. If the number of neutrons in the given atom is different, than it is an isotope.

a binary mixture is to be fed a continuous distillation column. calculate the minimum number of trays required to achieve a sepa
Taya2010 [7]

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
