Any substance that increases the concentration of 
in aqueous solutions is Arrhenius's acid.
<h3>What are Arrhenius acids?</h3>
Arrhenius define acids as substances with the chemical capacities to increase the concentration of hydrogen ion in aqueous solutions.
Thus, substances like HCl, HNO3, HBr, etc. would be considered an acid. This is because they ionize in aqueous solutions as follows:
HCl ---> +

The explanation for the large space between particles in a gas is provided by the kinetic theory (option C).
<h3>What is the kinetic theory?</h3>
The kinetic theory is a scientific theory used in physics to understand the behavior of gases.
This theory (kinetic theory) indicates that molecular distances in gases are small when compared to the molecular sizes.
In conclusion, the explanation for the large space between particles in a gas is provided by the kinetic theory (option C).

When KCL, which is an ionic compound is added to water it will dissociate and or ionize completely forming the ions of K+ and Cl-. The resulting solution would be a neutral solution, as the K+ is a cation of a strong base and Cl- is an anion of a strong acid, and whenever a strong base reacts with a strong acid, a neutral salt is produced
B. elements and compounds
Potassium or any other metals.
