For the generic equilibrium HA(aq) ⇌ H+(aq) + A−(aq), which of these statements is true? For the generic equilibrium , which of
earnstyle [38]

Answer:

The correct answer is The equilibrium constant for this reaction changes as the pH changes.

Explanation:

The equilibrium constant of a reaction depends of pH and viceverca.There is a equation that link pH with equilibrium constant Ka(for assumption).The equation is given below,

    pH=pKa+log[A-/HA]  

where[A-] is the concentration of conjugate base and [HA] is the concentration of conjugate acid.

Which ion has the same electron configuration as an atom of He?
mariarad [96]

Answer;

H- (negatively charged hydrogen ion)

Explanation;

The hydrogen ion has the same electron configuration as an atom of Helium. -Hydrogen ion is formed when a hydrogen atom loses or gains an electron. A positively charged ion is formed when hydrogen atom loses an electron (remaining with zero electrons) while a negatively charged ion (H-) is formed when a hydrogen atom gains an electron thus having 2 electrons.

-Helium atom has two electrons, therefore, it is similar with an negatively charged hydrogen.

<h3>What do we know about the process of dissolution?</h3>

A solute can dissolve in a solvent in a solid, liquid, or gaseous phase to create a solution through the process of dissolution. Solubility. The greatest amount of a solute that may dissolve in a solvent at a particular temperature is known as its solubility. The solution is said to as saturated when the maximum amount of solute is present.

Several variables influence solubility, including:

  • The solute's concentration
  • The system's temperature
  • Pressure (for gases in solution)
  • The solvent's and solute's polarity
