Answer: Option (c) is the correct answer.
Explanation:
HF is a weak acid and not a strong acid. This is because fluorine is a highly electronegative atom and when it combines with a hydrogen atom then it will attract the valence electron of hydrogen atom more towards itself.
As a result, it will not dissociates easily to give hydrogen ion. Hence, it acts as a weak acid.
A neutralization reaction is defined as a reaction in which an acid reacts with a base to give salt and water. For example,
It is true that, spectator ions "appear in the total ionic equation for a reaction, but not in the net ionic equation".
Titration is defined as a process in which concentration of an unknown solution is determined using a solution of known concentration.
Thus, we can conclude that the statement HF, HCl, and HNO3 are all examples of strong acids, is false.
The correct answer is Electrical Energy.

KCl is an ionized salt which readily dissolved in water and generate potassium and chloride ions. In which potassium posses one unit positive charge and chloride posses one unit negative charge. As water is a polar solvent there are partial positive and negative charge on the hydrogen and hydroxide ion respectively. The high solubility of the potassium chloride (KCl) in water is due to the stabilization of the ions in the polar solvent. The solvation of the ions can be shown as-
<span>Before this we need to know the correlation between volume in liters (l) and in cubic cm (cmł), 1 l = 1000 cmł. Then we need to under stand the correlation between cubic cm (cmł) and cubic mm (mmł), 1000 cmł = 1 000 000 mmł.
Finally all we have to do is calculating the volume of the cube, because all side have the same length, the math is simple. Calculating the content for any rectangle shape is width times length times height.
So in this case 20 cm * 20 cm * 20 cm = 8000 cmł as seen before this is a total of 8000 cmł = 8 000 000 mmł or 8 liters of fluid.</span>
