Respuesta :
That is only the combustion of a hydrocarbon. Rust is a combustion reaction because oxygen is added.
Fe(s) + O2(g) => FeO2(s)
Fe(s) + O2(g) => FeO2(s)
Answer: Because some of the processes are also known as incomplete combustion.
Explanation:
Combustion reaction is defined as the chemical reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide gas and water molecule. The chemical equation for this reaction follows:
[tex]\text{hydrocarbon}+O_2\rightarrow CO_2+H_2O[/tex]
If supply of oxygen gas is limited, it is known as incomplete combustion and carbon monoxide gas is also produced as a product. The chemical equation for this reaction follows:
[tex]\text{hydrocarbon}+O_2\text{(limited)}\rightarrow CO+CO_2+H_2O[/tex]
Thus, we cannot say that all the combustion reactions produce carbon dioxide and water as products because it depends on the supply of oxygen gas.
