As given in statement:
[H+] = 10^-12
<span>Formula for pH:
pH = -log [H+] </span>
<span>Putting the value of H+ ion in formula:
pH = -log ( 10^-12) </span>
<span>pH = 12.0 </span>
<span>
pH 0-6 (Acidic)
pH 7 (neutral)
pH 8-14 (basic)
A solution with pH 12.0 is basic.
So according to above explanation
</span><span>a. The solution is basic in nature, is the correct answer.</span>
The answer is yes. It's even safer compared to doing it from outside the vehicle.
Given:
mass of chlorine = 31.5 grams Cl2
temperature of water = 35 degrees C
volume of chlorine = 15 L
*water levels are equal
assume ideal gas behavior
Vapor pressure of water at 35 C = 42.2 torr
To solve for the barometric pressure, use the ideal gas equation:
PV = nRT
where P = Pgas - Pwater
(Pgas - 42.2 torr) * 15 L = 31.5g/70.9g/mol * (35 + 273) K * (760 torr * 22.4 L/298K)
solve for Pgas
Pgas = 563.36 torr
Therefore, the barometric pressure is 563.36 torr.
Answer: B
I hope this helps and have a wonderful day filled with joy!!
