What is a major difference between a chemical reaction and a nuclear reaction? A) Only chemical reactions release light. B) Only
2 answers:
Answer: Option (C) is the correct answer.
Explanation:
A nuclear reaction is a reaction which brings change in the nucleus of an atom.
For example,
A chemical reaction is a reaction which results in the formation of new compounds which have different properties than their reactants.
Hence, in a nuclear reaction changes in an atom occurs whereas in a chemical reaction changes in a compound or molecule occurs.
Thus, we can conclude that a major difference between a chemical reaction and a nuclear reaction is that only nuclear reactions can change the identity of the atom.

Explanation:
Part a
Normal Phase Chromatography
In the normal phase chromatography, the eluting power is highest for the solvent which has the highest polarity.
So from the given solvents as Methanol, Dichloromethane and Ethyl Acetate
the relative polarities are given as
Methanol=0.762
Dichloromethane (methylene chloride)=0.309
Ethyl Acetate=0.228
So the numbers are given as
Methanol :1
Dichloromethane (methylene chloride):2
Ethyl Acetate:3
Reverse Phase Chromatography
In the reverse phase chromatography, the eluting power is highest for the solvent which has the lowest polarity.
So from the given solvents as diethyl ether , water and toluene
the relative polarities are given as
Diethyl ether=0.117
Water=1.0
Toluene=0.099
So the alphabets are given as
Toluene :A
Diethyl ether: B
Water:C
