This polymer is made from a small molecule that repeats itself. The small molecule has two carbon atoms and four hydrogen atoms. The polymer is a widely used plastic. What is this polymer?

Polyethylene

Explanation:

Polyethylene is made of the ethylene monomer (C2H4). Polyethylene is a linear, manmade, addition homopolymer used in the manufacturing of plastic materials.

Polyethylene is a light weight synthetic polyolefin used for many different purposes. High density and low density polyethylene materials are available and used for different purposes.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
