Answer:
The substance is most likely NaCl.
Explanation:
Solubility:
As stated in statement the substance is insoluble in CCl₄ (Tetrachloromethane), it shows that the substance is polar in nature. In given options only C₁₀H₈ is soluble in CCl₄ because both are non polar in nature and like dissolves like. Hence, C₁₀H₈ is rejected.
Density:
Now, we are left with three options. NaCl, FeCl₃ and SiO₂. The student found that the density of substance is 2.20 g.mL⁻¹. Which is very close to the density of NaCl (i.e. 2.165 g.mL⁻¹). Therefore, most probably the substance the student is dealing with is Sodium Chloride.
The medium that might be used to cool the hot liquid coming from a reactor is : ( C ) Heat exchanger
<h3>Function of the heat exchanger</h3>
Heat exchanger is used for the transfer of heat between liquids to be used in a chemical reaction, It can be used for both Cooling and heating to achieve the desired temperature.
The liquid coming from a reactor which posses a very high temperature will be passed through the heat exchanger so that its temperature will attain the required temperature for the experiment.
Hence we can conclude that The medium that might be used to cool the hot liquid coming from a reactor is Heat exchanger.

I would say the C, the windward side, sense it is wetter. Hope this helps. :)
A hydrogen bond is formed by attraction between + and - charges on different water molecules.
Basically, it is the bond between two atoms that already participate in other chemical bonds. Hydrogen bonds may form between atoms within a molecule or between two separate molecules.
