Which monomer is formed when the trimer c9h20o4 is broken down into its monomers?

Belonging to the large family of alcohols, propylene glycol is a chemical element widely used by the food industry thanks to its recognized emulsifying properties. It is referable to its acronym E1520. This colorless, low volatile and soluble diol is also used in many other industries. Pharmaceutical, cosmetic, aeronautic, textile industries ... Propylene glycol is involved in the composition of many polymers such as polyester. Non-toxic when inhaled, propylene glycol is used in electronic cigarette filling fluid to produce an aerosol effect comparable to that of smoke.

With respect to polypropylene glycol, each condensation of propylene glycol causes a loss of a water molecule

C3H8O2 + C3H8O2 + C3H8O2 ==> C9H20O4 + 2H2O

the answer to your question is slate

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
