A polymer is a single chained molecule that is  made up of repeating subunits called monomers. In contrast, a composite is a material that is made from combining two or more molecules with similar physical or chemical properties to produce a hybrid molecule.

Plywood- it is a composite made from sticking together thin strips of wood with glue to ake stable sheets.

Plastic- a polymer made of repeating units called monomers of some kind of organic compounds.

concrete- is a composite made from mixing water cement and rocks. The mixture is not repeating and can branch in different ways which discounts it from being a polymer.

fiberglass- is a composite made that has no repeating units but made from plastic and glass fiber.

paper- is a polymer made of a repeating units of a specific monomer.

nylon- is a polymer manufactured by reacting repeating units of monomers.

Some organic solvents do not work well in liquid-liquid aqueous extractions. Ethanol (HOCH2CH3) is a common inexpensive solvent,
erica [24]

Answer:

See explanation

Explanation:

Extraction has to do with the separation of the components of a mixture by dissolving the mixture in a set up involving two phases. One phase is the aqueous phase (beneath) while the other is the organic phase (on top). The solvents used for the two phases must not be miscible. Water commonly is used for the aqueous phase.

Ethanol is an important solvent in chemistry but the solvent is miscible with water in all proportions. As a result of this, ethanol is a poor solvent for carrying out extraction.
