Which best explains the difference between a monomer and a polymer?
a monomer is larger than a polymer.
a monomer contains carbon and a polymer does not.
a polymer contains carbon and a monomer does not.
a polymer is larger than a monomer.

A polymer is larger than a monomer.

Explanation: A polymer is formed by the repeated addition of small units called as monomers. Thus a polymer is always larger than a monomer.

If a monomer contains carbon, the polymer would also contain carbon as combination of monomers produce polymers. For example:

       ethene                           polythene

Small molecules of ethene polymerizes to form a large molecule polythene.

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
