Melt chocolate and measure the temperature and then melt wax and measure the temperature and compare his results.
Some
of the solutions exhibit
colligative properties. These properties depend on the amount of solute
dissolved in a solvent. These properties include freezing point depression, boiling
point elevation, osmotic pressure and vapor pressure lowering. Calculations
are as follows:

ΔT(freezing point) = (Kf)mi
3 = 1.86 °C kg / mol (m)(2)
3 =3.72m
m = 0.81 mol/kg</span>

Answer:
Covalent bond
Explanation:
they will make a covalent bond with each other because both are non- metals and have a low electronegativity difference.
