A mixture of 40 mol % isopropanol in water is distilled at 1 atm by differential distillation until 70 mol % of the charge has b
1 answer:
Answer:
Explanation:
From the given information:
The percentage wieght of mixture = 0.4
The distillate = 70
From equilibrium data in Exercise 7.33
The Feed W = 100
The Liquid residue F = Feed(W) - Distillate (D)
= 100 - 70 = 30
By applying rayleigh equation;
From the plot of the graph of ; the area under the curve is being calculated between the point {
}.
Such that; the area = 1.209
Similarly, the value of xF = 0.067
∴

Visual representation of covalent bonding indicating the valence shell electrons in the molecule, lines represents the shared pair of electron and pair of electrons that are not involved in bonding are represented as dots(lone pairs) are known as Lewis structures.
Compound formation takes place in order to complete the octet of each element that is according to octet rule, each atom forms bond with other atom in order to complete their octet that is to get eight electrons in its valence shell and attain stability.
An organic compound of the form is known as ketene.
The given ketene is .
The number of valence electron of:
The number of valence electrons in =
2 electrons are involved in each single bond between carbon and hydrogen and 4 electrons are involved in each double bond formed between carbon-carbon and carbon-oxygen. Hence, the total number of electrons involved in bond formation are 12 and rest 2 pair of electrons are present on oxygen as lone pair of electrons.
Therefore, the attached image is the Lewis structure of .
