Answer:
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

The resulting solution will be neutral having a pH of 7.
<h3>What is the pH?</h3>
The term pH is defined as the hydrogen ion concentration in solution. We know that the pH is inversely related to the hydrogen ion concentration in solution.
We know that the reaction between an acid and a base produced a salt. In this case, the salt that is produced is neutral because the acid is completely reacted with the base.
Since the solution contains a mixture of a containing pH of 3.5 and that of a pH of 10.5, the resulting solution will be neutral having a pH of 7.

Answer:
1. The concentration of is equal to the concentration of : False
2. The rate of the dissociation of is equal to the rate of formation of : True
3. The rate constant for the forward reaction is equal to the rate constant of the reverse reaction: False
4. The concentration of divided by the concentration of is equal to a constant : False
Explanation:
The concentrations of reactant and product is constant and not equal.
The rate of forward and backward reactions are equal. Thus rate of the dissociation of is equal to the rate of formation of
For a reversible reaction, the equilibrium constant for the forward reaction is inverse of the equilibrium constant for the backward reaction and not equal.
Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.
