Explanation:
Compounds in order of increasing acidity will be written as d<c<b<a.
<h3>What is acidity?</h3>
The quantity of hydroxyl ions that a basic molecule may create in an aqueous solution is what is known as the acidity of bases. The quantity of hydronium ions that a substance may create in an aqueous solution determines how basic an acid is.
a, b are more acidic than c and d because of OH group attached to sp2 hybridised carbon which provide resonance stability for conjugate base
in c f has -I effect which increases acidity in a, NO2 has -m effect which increases acidity so increasing order is d<c<b<a
that is cyclohexanol < 2,4-difluorocyclohexanol < phenol < 2,4-dinitrophenol

It evaporates as the CO2 transitions from solid to gas form.
A mixture can be separated. Everything in a mixture keeps it's own properties and are not chemically joined together. I am not completely sure about the compound. Although with the cake example, the ingredients have been mixed and kind of "fused" together upon baking. Hope this helps a little. (P.S. trail mix is a good example of a mixture.)
