Explanation: All the Arrhenius and Bronsted Lowry acids release ions in solution.
According to Arrhenius and Lowry, acids are substances which release ions when dissolved in water.
Thus all are considered as acids,
Answer:
H+ ions
Explanation:
Acid release H+ ions in water after dissociation while bases release OH⁻ ions in solutions.
During dissociation, acid releases H+ ions which are characterized by losing electron with small charge charge density while bases release OH⁻ ions which have high charge density.
Typical dissociation reaction
1. HCL ⇄ H⁺ + CL⁻
In the above reaction, HCL releases H+ ion in the solution.
2. NaOH ⇄ Na⁺ + OH⁻
While in this second reaction, OH⁻ is relased into the solution.
This illustration is backed by Arrhenius theory which defined acid as substance that produce H+ ions in solutions.

Answers
With an increase in the kinetic energy of the solid molecule the intermolecular bonds become weaker, temperature increases, melting and molecules vibrating faster are changes.
What is the effect of the increased kinetic energy?
Kinetic energy is the form of the energy that is present in an entity in motion. When the kinetic energy is increased then the temperature of the particles increases and leads to evaporation.
The increased kinetic energy weakens the intermolecular bonds of the liquid particles and the molecules of the particles start vibrating fast.
Therefore, option b. intermolecular bonds become weak, option e. evaporation, option f. temperature increases and option h. molecules vibrate faster are the changes.

Final answer:
The changes that increase the kinetic energy of liquid particles are B, E, F, and H which correspond to evaporation, temperature increases, and molecules vibrating faster.
Explanation:
The changes that would be accompanied by an increase of the kinetic energy of particles in a liquid are evaporation, temperature increases, and molecules vibrate faster. During evaporation, molecules gain sufficient energy to overcome intermolecular forces and enter the gaseous phase. When the temperature increases, the average kinetic energy of the molecules increases, causing them to vibrate faster. Consequently, the correct answer is B, E, F, and H.
The changes that would be accompanied by an increase of the kinetic energy of particles in a liquid are B, E, F, and G.
When temperature increases, the average kinetic energy of the particles in a liquid also increases. This is represented by changes B and F. Evaporation (change E) also leads to an increase in the kinetic energy of the particles as they gain enough energy to escape into the vapor phase. Lastly, intermolecular bonds becoming weaker (change G) allows for more movement of the particles, increasing their kinetic energy.
