Answer:
The rusting of iron is represented by the equation 4Fe +3O2 --> 2Fe2O3.
Step-by-step explanation:
The equation for the rusting has been [tex]\rm 4\;Fe\;+\;3\;O_2\;\rightarrow\;2\;Fe_2O_3[/tex]. Thus Option C is correct.
Rusting has been the process of formation of iron oxide with the reaction of iron with oxygen in the presence of moisture.
The rusting reduce the life of iron, as the chemical reaction utilizes the iron of the material. Many practices have been performed for the prevention of material from rusting, such as the application of paint, etc.
The reaction of Fe with oxygen gives, iron oxide.
The reaction wiil be as follows:
[tex]\rm Fe\;+\;O_2\;\rightarrow\;Fe_2O_3[/tex]
Balancing the equation:
[tex]\rm 4\;Fe\;+\;3\;O_2\;\rightarrow\;2\;Fe_2O_3[/tex]
Thus the equation for the rusting has been [tex]\rm 4\;Fe\;+\;3\;O_2\;\rightarrow\;2\;Fe_2O_3[/tex]. Thus Option C is correct.
