During the complete combustion of propane (C_3H_8), what other product is formed besides carbon dioxide (CO_2)?
A
Water (H_2O)
B
Oxygen (O_2)
C
Nitrogen gas (N_2)
D
Methane (CH_4)
Verified step by step guidance1
Identify the chemical formula of propane, which is \(C_3H_8\), and recognize that complete combustion involves reacting a hydrocarbon with oxygen (\(O_2\)).
Write the general form of the complete combustion reaction for a hydrocarbon: \(C_xH_y + O_2 \rightarrow CO_2 + H_2O\).
Understand that during complete combustion, carbon atoms in the hydrocarbon are converted to carbon dioxide (\(CO_2\)), and hydrogen atoms are converted to water (\(H_2O\)).
Balance the combustion reaction by ensuring the number of carbon, hydrogen, and oxygen atoms are equal on both sides of the equation.
Conclude that besides carbon dioxide, water (\(H_2O\)) is the other product formed during the complete combustion of propane.
