Once ethylene is made, it reacts with other ethylene monomers to make polyethylene.


Long polyethylene chains can be arranged in different ways. If these chains line up side by side, high-density polyethylene, or HDPE, is made.


Select the true statements.

A. HDPE is made of long side by side chains of polyethylene
B. ethylene is a polymer
C. many ethylene molecules are joined together to form polyethylene
D. polyethylene is made of carbon and hydrogen

The true statements are:

A. HDPE is made of long side by side chains of polyethylene
C. many ethylene molecules are joined together to form polyethylene
D. polyethylene is made of carbon and hydrogen

Statement B is not true because ethylene itself is not a polymer; it is a monomer that can polymerize to form polyethylene.
