Question

Which statement about polymers is true?

A) polymers are substances that have relatively large molecules

B) Oil and gas are the starting materials for making all polymers

C) fabrics such as cotton and silk are synthetic polymers

D) all polymers are obtained from living organisms

Answer 1

A.) polymers are relatively large molecules because they are long chains of smaller ones.

Answer 2

A) polymers are substances that have relatively large molecules

Step-by-step explanation:

Polymers are large molecules formed by the condensation or polymerization of small molecules. The small molecule is called a monomer. A monomer is the building block of a polymer.

For example protein is a polymer which is made up of monomers of amino acids. Polyethylene is a polymer which is made up of monomers of ethylene.
