Question

If one were to attempt to mix carbon dioxide and hexane at 0°C and under very high pressure, what would that person likely observe? (* The boiling point of carbon dioxide is well below 0°C).

A) The substances will mix uniformly.
B) The substances will separate into two separate layers of liquid.
C) The substances will separate into two separate layers, a liquid and a gas.
D) The two substances will mix but then hexane will separate by rising to the top of the solution.

Answer 1

I think the accurate answer to this question, based from the sources,  is A) The substances will mix uniformly. Carbon dioxide and hexane at 0C exposed at extreme pressure will be able to mix together.Thank you for your question. Please don't hesitate to ask in Brainly your queries

Answer 2

Answer: The correct option is A.,

Explanation: We are given two compounds: carbon dioxide and hexane.

These two compounds are non-polar in nature.

When the two compounds are kept under high pressure, the two gases will mix uniformly.

This is explained by Henry's Law: This law states that the mass of gas dissolved in a given volume of liquid at constant temperature is directly proportional to the pressure of the gas present in equilibrium with the liquid.

$m\propto p$

At high pressure, more amount of gas will be dissolved in the liquid.

So, at high pressure, the solubility of the gases increases and hence, the compounds gases will mix uniformly.
