The addition of magnesium chloride to the solution results in unaffected chemical equilibrium of the system. Thus, option A is correct.
The given chemical equation has been:
The reaction is reversible and can be converted back to the reactant with the increase in the product concentration. The equilibrium has been the condition when the concentration of products and reactants in the reaction are equal.
With an increase in products or reactants, there has been a corresponding chemical shift in the equilibrium.
The addition of Magnesium chloride in the solution, results in the dissociation of compound as:
The compound results in neither the increase of reactants, nor increase of product concentration in the acetic acid equilibrium.
Thus, the equilibrium of the system will remain unaffected by the addition of magnesium chloride. Thus, option A is correct.

The pH of an aqueous solution that has a concentration of 0.35 M NaF and pKa for HF = 3.14 is 3.6.
<h3>How to calculate pH?</h3>
The pH of a solution refers to the degree of acidity or alkalinity of the solution. It can be calculated using the Henderson-Hasselbalch Equation as follows:
pH = pka + log ([A-]/[HA])
Where;
- A- = conjugate base
- HA = weak acid
pH = pKa + log([F-]/[HF])
pH = 3.14 + log(1/0.35)
pH = 3.14 + 0.4559 = 3.595
Therefore, the pH of an aqueous solution that has a concentration of 0.35 M NaF and pKa for HF = 3.14 is 3.6.

Answer: An imbalance of electric charge I the surface of an object
-electric charges that are stationary or at rest
-charges that build up on an object
Answer:
Explanation:
Many elements have similar properties. This can be seen in how periodic table is arranged. The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties.
For eg: Lithium, Sodium, and Potassium fall under group one in periodic table. These elements exhibit similar properties such as being extremely reactive.
