<h2>Answer:</h2>
pOH = 4.6
<h2>Explanations:</h2>
The sum of pH and pOH of a solution is 14as shown:
Given the following parameter
pH = 9.4
Substitute the given parameters into the formula to have:
Hence the pOH of the solution of pH of 9.4 is 4.6
A molecule is usually reserved to represent the smallest particle of a compound.
The pressure on the inside of the other side of the bottle is; 130kPa and this is by virtue of Pascal's Principle.
<h3>Pressure and Pascal's Principle</h3>
According to Pascal’s principle, otherwise called Pascal’s law, in fluid (gas or liquid) mechanics, the statement goes thus, In a fluid at rest in a closed container, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container in which the fluid is contained.
On this note, it follows that the pressure is transmitted to the walls of the bottle.

The net ionic equation of the reaction is:
- Pb²⁺ (aq) +2 I⁻ (aq) → PbI2(s)
<h3>What are net ionic equations?</h3>
Net ionic equations are equations where ions which remain in solution known as spectator ions are not shown in the equation. Only ions involved in formation of product are shown.
In the given equation, sodium and nitrate ions are spectator ions.
The net ionic equation of the given reaction is as follows:
- Pb²⁺ (aq) +2 I⁻ (aq) → PbI2(s)
In conclusion, spectator ions are not shown in net ionic equation.
