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
Brief Explanations:
Polymers are large - molecules made up of repeating subunits. A long chain of carbon atoms with hydrogen atoms attached is a characteristic structure of a polymer. Option A is a specific hydrocarbon with a fixed number of atoms and not a polymer. Option B is an ionic crystal (sodium fluoride). Option D is a cyclic molecule. Option E is a simple ionic compound (calcium chloride).
Answer:
C. a long chain of carbon atoms with hydrogen atoms attached to them
