During the course of analyzing an unknown chemical, a chemist determines that the chemical is composed of carbon, hydrogen, and oxygen in the proportion of 1 carbon to 2 hydrogens to 1 oxygen. the chemical is
a.) amino acid
b.) dna
c.) a triglyceride
d.) a protein
e.) a monosaccharide

The correct answer for this one, is e. because CH2O is a chemical compound of the aldehyde type and the aldehydes are only at the monosaccharides (carbohydrates)

Explanation:

As you should know, amino acid contains a carboxyl group and an amino group, DNA it is compounded by  a pentose, nitrogen base and a phosphate group, the triglyreceride are  long chain fatty acid compounds, so much of CH2O. The proteins are very complex structures to have only those elements.

the answer is 75.0%.
