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.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
