<h2>Answer with Explanation </h2>
The energy transformation involved in heating soup in microwaves occurs due to microwave radiation. The radiant energy which also known as heat energy in the microwave causes the water molecules in the soup to gain kinetic energy. Hence, the molecules collide with each other more often causing the soup to heat up in form of waves that are built within the microwave. This is also the reason it is termed as mircowave due to release of waves.
The compound sodium carbonate is a strong electrolyte because it completely dissociates when placed in water into its component ions. The equation of the reaction can be expressed as:

The dissociation leads to the formation of sodium and carbonate ions with the latter held together by its internal covalent bond.
This is unlike weak electrolytes that do not dissociate completely in water or aqueous solutions. Only a small fraction of the solute exists as ions in the solution.
