<h3>What are spectator ions?</h3>
Ions that are not involved in the actual chemical reaction are called spectator ions.
A precipitation reaction occurs when two ionic compounds react to produce a precipitate and an insoluble substance which stays in the solution as a spectator ion.
Hence, Potassium and Nitrate ions are spectator ions in the reaction:

The force reduces
Explanation:
According to Coulomb's law, the force between the charges will reduce if the separation between the charges increases.
Coulomb's law states that "the force between two charges is a directly proportional to the product of the magnitude of the charges and inversely proportional to the square of their separation.".
F = 
where F is the electric field force
K is the constant of the field
is charge 1
is charge 2
r is the separation
We see that the separation is inversely proportional to the force between the charges. The larger the separation, the weaker or smaller the force.

The formula here is:
pH = -log[H+]
3.6 = -log[H+]
[H+] = 2.51 x 10⁻⁴ mol / Liter
The first option is correct.
To solve this we use the
equation,
M1V1 = M2V2
where M1 is the concentration of the stock solution, V1 is the
volume of the stock solution, M2 is the concentration of the new solution and
V2 is its volume.
<span>3.26 x 1.52 = 13.26 x M2</span>
<span>M2 = 0.37 mg/mL</span>
The answer is TRUE because in that ecuation there are 6 atoms or moles of mercury in both sides and you also have the required moles of oxygen
