Answer:
two north poles and two south poles
Explanation:
A single magnet has a north pole and a south pole. If it is broken into two pieces, then each of the two pieces will have a north pole and a south pole.
No matter how many times or into how many pieces a magnet is broken, the resulting pieces will have two poles each.
Answer:
a. Dipole-dipole bonding
Explanation:
SO2 has dipole-dipole bonding. This is because of the difference in the electronegativities of Sulphur and oxygen. Moreover, the lone pair of electrons on S gives it bent shape with a net dipole unlike CO2 which has a linear shape.( This why CO2 does not have any dipole moment).
So, the correct answer is a.
Answer:
1 - e, 2 - k, 3 - a, 4 - i, 5 - b,
Explanation:
The ratio of the amount of analyte in the stationary phase to the amount in the mobile phase. --- Retention factor.
Time it takes after sample injection into the column for the analyte peak to appear as it exits the column. -- Retention time
The process of extracting a component that is adsorbed to a given material by use of an appropriate solvent system. -- Elution
Measure of chromatographic column efficiency. The greater its value, the more efficient the column. -- Theoretical plate number
Gas, liquid, or supercritical fluid used to transport the sample in chromatographic separations. -- Mobile phase
Immiscible and immobile, it is packed within a column or coated on a solid surface. -- Stationary phase
