Iron rusts when exposed to oxygen. Iron(II) is produced in the reaction. How many moles of oxygen oxide will react with 2.4 mol of iron in the rusting reaction?

Answer 1

Iron has a rich redox chemistry..............

#Fe(s) + 1/2O_2 rarr FeO(s)#

This is a very simplified representation of the oxidation of iron metal. But if there are #2.4*mol# of iron metal, it should react with #1.2*mol# of dioxygen gas to give #2.4*mol# of iron oxide, as per the stoichiometric equation.

Rust is a surface phenomenon that happens to steel structures like bridges.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
