Dr. Lange discovers a colony of bacteria living in an extremely acidic environment. While observing the colony, she finds tWhich best describes the bacteria discovered by the scientist? They are probably archaebacteria because they are autotrophs.

Polymers are large molecules composed of simple units repeated many times. Thus, they often have relatively simple empirical formulas. Calculate the empirical formulas of the polyethylene: 86% C, 14% H. You must show all work for credit.
