this is the answers and working out to both questions
Each proton serves as a positive charge and each electron serves as a negative charge. The two charges neutralize each other on a 1:1 ratio. In your question, you have 12 protons to 13 electrons. That means there's a net -1 charge because there is one more electron than protons.
The new pressure changed relative to the original by a factor of 8/3.
<h3>What is the change in the pressure?</h3>
Using the ideal gas equation;
PV = nRT
P = pressure
V = volume
n = number of moles
R = gas constant
T = temperature
P1 = nRT/V
P2 = 4n * R * 2T/3V
Hence;
P2/P1 = 4n * R * 2T/3V ÷ nRT/V
P2/P1 = 4n * R * 2T/3V * V/nRT
P2/P1 =4 * 2/3
= 8/3

Answer :
Explanation : The ideal gas law, states that PV = nRT;
where, P is pressure;
V is volume;
n is number of moles
R is gas constant
T is temperature
If there are two entities to be compared then, it can be compared as,
;
as n and R can be considered as a constant.
Therefore, at constant pressure, the equation will get modified as;
