a) Ca(s) - Ca2+ (aq)

b) Hg() - Hg22+(aq)

c) Fe2+(aq) - Fe3+(aq)

Answer:

D

Explanation:

Option D is the right answer. A substance that has been reduced undergoes chemical reduction. They show the following properties;

  1. Removal oxygen from the species. Option D goes from 3 oxygen to just 1 oxygen.
  2. Addition of hydrogen to a specie.
  3. Gain of electrons by an atom.
  4. Decrease in oxidation number of an atom.
  5. Decrease in the number of electronegative atoms surrounding an element in changing from reactants to products.

The equation that represents the process of reducing a specie is : ( D )

   NO₃ (aq) - NO(g)

The reduction of a specie is a chemical reaction process which  involves the removal of oxygen atom(s) and the the addition of hydrogen.  

A reduced specie gains/accepts electrons therefore becoming more electronegative  ( i.e. the number of electronegative atoms around it is reduced ) and It also experiences a decrease in its oxidation number

From the options provided the number of oxygen present in NO₃ reduces from O₃  to O  This makes option D the correct option representing the reduction of specie

Hence we can conclude that the The equation that represents the process of reducing a specie is

   NO₃ (aq) - NO(g)
