The electrons hold onto the nucleus because of the magnetism and the electricity. <span />
A measure of peak separation in a chromatographic method that equals the difference in retention time for two components divided by the average of their peak widths is the definition of resolution.
Retention time can be referred to as the amount of time a solute spends in the stationary and mobile phases of a column.
The analyte's interaction with the stationary phase determines the longer retention period.
The duration of retention will increase as the interaction becomes more strong.
Resolution is defined as the peak separation in a chromatographic procedure that is equal to the difference in retention time for two components divided by the average of their peak widths.

Answer:
3
Explanation:
H2O has a higher intermolecular force (hydrogen bonding) where N2 only has London Dispersion.
Answer:
Option E
Explanation:
As work is dot product of force and displacement
W=FdCos0
As Cos 0=1 so W=F.d(1)
W=F.d
as Cos 90=0 so no work will be done when angle between force and displacement is 90 degree. At angle between force and displacement is 180 degree then negative value com as Cos 180= -1
Answer:
-1
Explanation:
According to this question, the oxidation state/number of H and O in C2H4O is +1 and -2 respectively.
The oxidation state of carbon in the compound can be calculated thus:
Where;
x represents the oxidation number of C
C2H4O = 0 (net charge)
x(2) + 1(4) - 2 = 0
2x + 4 - 2 = 0
2x + 2 = 0
2x = -2
Divide both sides by 2
x = -1
The oxidation number of C in C2H4O is -1.
