Answer:
a. Larger molecular size
b. Ability to react with water
c. Polarity
d. Shorter bond length
Explanation:
Ethene is a larger molecule than oxygen and nitrogen hence it is more soluble than the both other gases .
SO2 dissolves readily in water to yield an acid solution. It is an acid anhydride.
Nitric oxide is a polar compound. It remains very much polar while nitrogen and oxygen are non polar.
Nitrogen is sp hybrized, this leads to a very short bond and does not easily interact with oxygen and nitrogen
According to Arrhenius concept a base is one which can donate hydroxide ion in its aqueous solution.
Here NaOH is a base as it can donate OH-.
As NaOH is a strong base it will have very high dissociation constant.
Due to high dissociation constant if will almost completely dissociate into sodium ions and hydroxide ions.
Thus in a solution of NaOH we will expect the following two ions
