Question

synthetic materials, natural resources quick check
what must happen for a natural resource to become a synthetic material? (1 point)
it needs to go through a chemical reaction.
it needs to be dried out.
it needs to go through a phase change.
it needs to be pounded very thin.

Explanation:

Synthetic materials are created from natural resources through chemical processes. A chemical reaction changes the molecular structure of the natural resource to form a new material. Drying out, phase change (like melting/freezing), or pounding thin are physical changes and don't create a new chemical substance.

Answer:

It needs to go through a chemical reaction.
