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
Every chemical reaction requires a minimum amount of energy to undergo reaction.
The total energy required is Threshold energy. The chemicals have some internal energy and they require some extra energy which is known as activation energy.
The reaction occurs when two molecules or atoms come closer to each other and for this they need kinetic energy.
Now for an effective collision the two molecules or atoms should collide with a minimum amount of energy so that they may undergo reaction so again they need some energy
These kinetic energy and energy for effective collision is actually called as activation energy.
Answer:
true
as temperatures rise, the atoms become more active; as per the opposite (meaning as temperatures drop, the atoms start to settle down) liquid is the more medium state (because the temperature rises enough for the solid to become a a liquid but not too much that the liquid evaporates and turns into a gas) have a great day/night
This is false
А
Because they are compounds, they cannot be pure substances.
Because:Compounds are pure substance
