What is the mole ratio between fe and fe2o3

-

2 : 1

Explanation: -

To calculate the required mole ratio, the first step is writing the balanced chemical equation for the formation of Fe2O3 from Fe.

The other element present with Fe in Fe2O3 is O oxygen.

Fe reacts with oxygen to give Fe2O3.

The balanced chemical equation for this reaction is

4 Fe + 3 O 2 --> 2 Fe2O3

Now from the balanced chemical equation we see

There are 4 moles of Fe.

We also see there are 2 moles of Fe2O3.

So their ratio is Fe : Fe2O3 = 4 : 2.

For ratio, we need the simplest.

Simplifying by diving by 2, we get Fe : Fe2O3 = 2 : 1

The mole ratio between Fe and Fe2O3 is 2 : 1.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
