Answer: B) Pure water

Explanation: Electrolytes are those solutions which consists of ions and thus can easily conduct electricity through them.

a) Ocean water contains dissolved minerals which act as electrolytes and hence act as a good electrolyte.

b) Pure water is present in undissociated form due to strong hydrogen bonding and thus due to the absence of ions, act as a non electrolyte.

c) Strong hydrochloric acid: is a strong acid which easily dissociates to give H^+ ions and thus act as good electrolyte.

HCl\rightarrow H^++Cl^-

d) Potassium chloride is a salt which act as good electrolyte due to easy dissociation of ions in water.

KCl\rightarrow K^++Cl^-

In sample B, we can clearly see that it is a mixture because the amount of solid recovered is much less than the total mass of the solid put into the beaker. The sample must have been separated into its components.

Alekssandra [29.7K]

A balanced nuclear reaction equation indicates that there is a rearrangement during a nuclear reaction, but of subatomic particles rather than atoms. Nuclear reactions also follow conservation laws, and they are balanced in two ways: The sum of the mass numbers of the reactants equals the sum of the mass numbers of the products.
