CH3CO2H(aq) + H2O(l) ⇄ CH3CO2-(aq) + H3O+(l)
Evgen [1.6K]
Correct Answer: Option C:<span> The equilibrium position will shift to the right toward the products. 

Reason:
1) This problem is based on </span>Le Chatelier's principle. It is stated as '<em>any</em><span><em> changes in the temperature, volume, or concentration of a system will result in predictable and opposing changes in the system in order minimize this change and achieve a new equilibrium state.</em>' 

2) In present case, the reaction involved is: 
</span><span>                 CH3CO2H(aq) + H2O(l) ⇄ CH3CO2-(aq) + H3O+(l) 
</span>Hence, when the concentration of acetic acid (reactant) is increased, the equilibrium will shift to right to minimize the effect of change in concentration of reactant.

"an acid is a substance that forms hydrogen ions when dissolved in water." this is an example of —
LenaWriter [7]

Answer is: this is an example of an Arrhenius acid.

An Arrhenius acid is a substance that dissociates in water to form hydrogen ions or protons (H⁺). 

For example hydrochloric acid: HCl(aq) → H⁺(aq) + Cl⁻(aq).

An Arrhenius base is a substance that dissociates in water to form hydroxide ions (OH⁻<span>). 
In this example lithium hydroxide is an Arrhenius base:</span>

LiOH(aq) → Li⁺(aq) + OH⁻(aq).

Most radiation is released as particles. Identify the type radiation that is not a particle.
Blizzard [7]

Gamma rays

Explanation:

Gamma rays is a form of electromagnetic radiation. It has zero mass and no charge.

Most radiations are particles but gamma rays are not particles they are mere rays.

  • They have an energy range between 10KeV and 3Mev
  • The range of gamma rays is not definite but it is very long.
  • The intensity of gamma rays for any medium decreases exponentially from the source.
  • Gamma rays are ionizing radiations
