Write the balanced equation for the half reaction for the single replacement reaction involving iron. This equation considers only the iron cations and the
elemental iron, and it shows how the iron cation (Fe3+) is reduced to become
elemental iron (Fe). How many electrons are represented in this equation? How
does this number of electrons help show a balance of charge on both sides of the
equation? (3 points)

Explanation:

The half reaction required

Fe⁺³ + 3 e = Fe

This is a balanced equation

No of atom of Fe on both side = 1

Total charge on the left side = + 3 - 3 = 0

Total charge on the right = 0

three electrons will be required to neutralise +3 charge on the single iron ion .

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.
