I'm giving 80 ! it has to be correct which statement best distinguishes carbon dioxide from carbon monoxide? a. one is a solid and one is a gas at room temperature. b. one has more oxygen atoms than the other. c. one has more carbon atoms than the other. d. there is no difference because the compound goes by two names.

The clue to the chemical composition of carbon monoxide and carbon dioxide and energy their names. Carbon MONoxide has one carbon atom and only one oxygen atom, as the prefix mon- means one; singular. It is written as CO.
Carbon Dioxide also has one carbon atom, but two oxygen atoms (a diatomic pair), as the prefix di- means two; twice the amount of something. It is written as CO2(the 2 should be smaller at the bottom of the O, sorry correct formatting isn't available on mobile)
So, your answer is B

Hey how did you manage to type such a big lab report
