Answer:
I believe it is B.
Explanation:
because an element is a for sure pure substance and I am sure a compound is too. I appologize if I am wrong.
Just choose one of them. Getting one question wrong isn't the end of the world.
I suggest water.
<span>The correct answer would be the fourth option. The compounds ethanol and 1-propanol are soluble to both water and hexane. Ethanol and 1-propanol are completely soluble in water as they both contain a polar end due to the hydrogen bonding present in the -OH functional group. Both are soluble in hexane since both contains a non polar end, the aliphatic hydrocarbon chain. Solubility of alcohols varies increasingly as the hydrocarbon chain increases since it makes them more non polar. However, for branched molecules, non polar properties would decrease. So, the best option from the list of choices would be ethanol and 1-propanol.</span>
