Answer: Option (d) is the correct answer.
Explanation:
Carbon tetrachloride
is a non-polar solvent. Whereas out of the given options,
,
,
, and HI are all polar molecules.
On the other hand, only
is non-polar molecule.
Also it is known that like dissolves like.
So, being non-polar
will dissolve the give alkane,
.
This example is an controversial matter because melting an candle is considered as both physical change and chemical change because no new substances were made by melting an candle. The final answer is C.

Energy(heat) required to raise the temperature of water : 418.6 J
<h3>Further explanation </h3>
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
Specific heat of water = 4.186 J/g*C.
∆T(raise the temperature) : 10° C
mass = 10 g
Heat required :
