Multiple Choice
When a hydrocarbon burns completely in air, which of the following is a component produced?
A
SO_2
B
NH_3
C
CO_2
D
H_2
Verified step by step guidance1
Understand that a hydrocarbon is a compound made only of carbon (C) and hydrogen (H) atoms.
Recall that complete combustion of a hydrocarbon means it reacts fully with oxygen (O_2) to produce carbon dioxide (CO_2) and water (H_2O).
Recognize that sulfur dioxide (SO_2) is produced when sulfur-containing compounds burn, which hydrocarbons do not contain.
Note that ammonia (NH_3) contains nitrogen and is not a product of hydrocarbon combustion since hydrocarbons do not contain nitrogen.
Conclude that the main carbon-containing product of complete hydrocarbon combustion is carbon dioxide (CO_2), not SO_2, NH_3, or H_2.
