The given balanced reaction is,

4Fe(s) + 3O_{2}(g) --->2Fe_{2}O_{3} (s)

The stoichiometric coefficients of each element or compound represents the number of moles of that element or compound required for the complete reaction to take place.

The mole ratios of different products and reactants will be:

\frac{Fe}{O_{2}} = \frac{4 mol Fe}{3 mol O_{2}}

\frac{Fe}{Fe_{2}O_{3}} = \frac{4 mol Fe}{2 Fe_{2}O_{3}}

\frac{O_{2}}{Fe_{2}O_{3}} =\frac{3 mol O_{2}}{2molFe_{2}O_{3}}

So the mole ratio comparing iron (Fe) and oxygen gas (O_{2}) is

How do surface waves form?
ivann1987 [24]
Ocean surface waves are surface waves that occur at the surface of an ocean. They usually result from distant winds or geologic effects and may travel thousands of miles before striking land. They range in size from small ripples to huge tsunamis. There is surprisingly little actual forward motion of individual water particles in a wave, despite the large amount of forward energy it may carry.
