Answer:
in lewis structure, a solid line is usually used to represent a bond between the atoms
Explanation:
the dots that are shown around the atom represent the valence electrons on the outer shell
when there are multiple atoms, either a pair of dots circled (one dot from each atom) or a solid line is used to show the bonds between those atoms
Answer:
I think that the answer is A.
Answer:
I think it is mixture and of chemical reaction
We see in the given name of the hydrocarbon that the root word is pentane from 2,2,4-trimethylpentane. Pentane is a hydrocarbon chain that contains 5 carbon atoms. Therefore, the answer to this item is 5 carbons.
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
