A chemical equation is shown below. FeCl_3 + NaOH → NaCl + Fe(OH)3 What are the coefficients that should be added to balance this equation? Use complete sentences to explain your answer. Explain how this chemical reaction demonstrates the conservation of mass. (10 points)

FeCl₃ + 3 NaOH → 3 NaCl + Fe(OH)₃

Explanation:

To balance a chemical reaction, we should maintain the stichiometry of all elements.

Also, we should demonstrate the conservation of mass that states "The mass doe not destroyed or created from nothing but it can transferred from form to another one".

Thus, by balancing the chemical reaction we are applying the conservation of mass.

That in our example, the number of atoms of each element in the reacting and products sides must be equal.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
