Answer:-
Ca-Cl
Explanation:-
The more the difference in electronegativity more the polar bond.
In case of Ca-Cl the difference = 3.16 - 1= 2.16
It is more than all the other combinations given.
Hence Ca-Cl is the most polar covalent bond.

Answer:
C₃H₃NaO₂
Explanation:
The percentage composition of the artificial snow is given.
The smallest whole number ratio of the atoms in a compound gives the empirical formula.
To find the empirical formula of the artificial snow, we use the method below;
Percentage composition of oxygen = 100 - (38.3+3.33+ 24.4) = 33.97
Elements C H Na O
Percentage
Composition 38.3 3.22 24.4 33.97
Number of
moles 38.3/12 3.22/1 24.4/23 33.97/16
3.19 3.22 1.06 2.12
Divide by
the smallest 3.19/1.06 3.22/1.06 1.06/1.06 2.12/1.06
3 3 1 2
The empirical formula of the compound is C₃H₃NaO₂
