If carbon monoxide reaches a temperature of over 1,100 degrees Fahrenheit, it will ignite in a combustion reaction with oxygen. What would the product(s) of the reaction be?2CO + O2 → ?2CO2C2 + O42CO + O2H2O

Carbon monoxide reacts with oxygen to form carbon dioxide. The balanced reaction is 2CO + O2 → 2CO2: two CO molecules contain two carbon atoms and two oxygen atoms, and O2 adds two more oxygen atoms, giving two CO2 molecules. Therefore, the product is 2CO2, choice A.
