Define nonelectrolytes, weak electrolytes, and strong electrolytes in terms of number of ions present in solution. ion dissociation in solution. molecular compounds or soluble ionic compounds.

The three definitions are listed in the explanation.

Explanation:

A nonelectrolyte is a molecular compound that does not consist of ions hence it does not dissociate into ions in solution.

A weak electrolyte is a soluble ionic compound that dissociates only to very small extent into ions in solution.

A strong electrolyte is a soluble ionic compound that dissociates completely into ions when dissolved in water.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
