Which phrase describes a polymer? a. a branching structure containing 10 carbon atoms and 22 hydrogen atoms b. a crystal containing many sodium ions and many fluoride ions c. a long chain of carbon atoms with hydrogen atoms attached to them d. a molecule containing six carbon atoms arranged in a ring structure e. a single atom of calcium bonded to two atoms of chlorine

Answer is: C. a long chain of carbon atoms with hydrogen atoms attached to them.

Starch is example of polymer.

Main component of bread is flour and main component of flour is starch.

Starch is a polymeric carbohydrate consisting of a large number of glucose units bonded by glycosidic bond. Starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol.

Another example, polystyrene is a synthetic aromatic hydrocarbon polymer made from the monomer styrene.
