Answer 3

Hi! I think @Festinger meant something else by,
"carbon dioxide is carbon-two-carbon, or CO2."
I think he meant, "carbon dioxide is carbon-two-oxygen, or CO2."

Molecules are usually given names that reflect what they are composed of.

In the future, the chemistry section might have people more qualified to help with questions like these.

After a little bit, the naming methods still make sense, but are a little more complicated.

Answer 4

Just for fun:
\(\sf CO_2\)
\(\sf H_2O\)
