APFIVE Principles of Complete Combustion
The complete combustion of a hydrocarbon, $$C_xH_y$$, produces carbon dioxide and water. All of the following statements about this reaction are true EXCEPT:
A
The water produced contains all the hydrogen atoms present in the original hydrocarbon, forming $$H_2O$$.
B
All the carbon atoms in the hydrocarbon can form carbon monoxide during complete combustion.
C
All carbon atoms in the hydrocarbon are converted entirely into $$CO_2$$ in a complete combustion.
D
The law of conservation of mass applies, ensuring the total mass of reactants equals the total mass of products.
