Answer:
pH = 11.7
Explanation:
<u>Given:</u>
[OH-] = 0.00500 M
<u>To determine:</u>
pH of the solution
<u>Explanation:</u>
pH refers to the H+ ion concentration in a given solution whereas pOH indicates the OH- ion concentration.
pH and pOH are related by the following equation:
![pH + pOH = 14 ------(1)](https://tex.z-dn.net/?f=pH%20%2B%20pOH%20%3D%2014%20------%281%29)
Here:
![pH = -log[H+]\\\\pOH = -log[OH-]](https://tex.z-dn.net/?f=pH%20%3D%20-log%5BH%2B%5D%5C%5C%5C%5CpOH%20%3D%20-log%5BOH-%5D)
When OH- = 0.00500 M
![pOH = -log(0.00500) = 2.30\\](https://tex.z-dn.net/?f=pOH%20%3D%20-log%280.00500%29%20%3D%202.30%5C%5C)
Based on equation(1):
![pH = 14 - pOH = 14 -2.30=11.7](https://tex.z-dn.net/?f=pH%20%3D%2014%20-%20pOH%20%3D%2014%20-2.30%3D11.7)

Explanation:
Answer:
B.C5H12 that is pentane
Explanation:
hydrocarbon has only hydrogen and carbon atoms
I got the answer !!! is Ar :))))
The total pressure in the container after the three gases are mixed is 6 atm and the partial pressure of He is 1 atm.
<h3>What is Dalton's Law of Partial Pressure ?</h3>
According to Dalton's Law of Partial Pressure , the pressure exerted by a mixture of gas is equal to the sum of the partial pressure of the gases in the mixture.
P(total) = p₁ +p₂+p₃+.....
As the volume of the containers are same and the
n = 1*5/RT for Helium
n = 2*5 /RT for Neon
n= 3*5/RT for Argon
Mole fraction = moles of the element/Total moles
Moles fraction of Helium is
![\rm \dfrac{1*5}{1*5+2*5+3*5}](https://tex.z-dn.net/?f=%5Crm%20%5Cdfrac%7B1%2A5%7D%7B1%2A5%2B2%2A5%2B3%2A5%7D)
= 1/6
Total Pressure in the container = 1 + 2 +3 = 6 atm
The partial pressure of Helium will be
=Mole fraction * Total pressure
=(1/6)*6 atm
= 1 atm , as the volume is same the temperature is same , the pressure will also be same.
