Question

15.) co (1 point)○ carbon oxide○ carbon monoxide○ monocarbon monoxide○ carbon (i) oxide

Explanation:

For covalent compounds with two elements, prefixes indicate the number of each atom. "Mono-" is used for the second element if there is one atom, and omitted for the first element when there is one atom. CO has 1 carbon and 1 oxygen atom, so it is named Carbon Monoxide.

Answer:

Carbon Monoxide
