Concepts and Reason
The concept of formation and balancing of chemical equations is used to solve this problem.
A molecular equation is to be written in a balanced way with the substance state. The compounds that are to be dissociated into ions are then shown in the form of an ionic equation. The spectator ions appearing on both the sides of the equation are to be cancelled out to obtain the net ionic equations.
Fundamentals
On the basis of an involvement of ions in the chemical reactions, the reactions can be categorized as molecular, net ionic and complete ionic equation. The chemical species that take part in a reaction are represented by the net ionic equation. In simpler terms, the net ionic equation facilitates the solubility rules as well as the recognition of polyatomic or monoatomic ions.
Answer:
(A)
The molecular equation of image is to be written first, then the net ions that are participating in the equation are identified.
Net ionic equations determine the chemical species that actually take part in a chemical reaction. The molecular and the ionic equation of the reaction between image is shown below:
