Answer:
B) The volume is the same for any gas.
Explanation:
Considering the ideal gas equation as:-
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 8.314 J/ K mol
At STP,
Pressure = 1 atm
Temperature = 273.15 K
So, applying the values we get that 1 mole of any gas occupies a volume of 22.4 L
Thus, correct option is:- B) The volume is the same for any gas.
Answer:
0.2320V
Explanation:
Voltage can be defined as the amount of potential energy available (work to be done) per unit charge, to move charges through a conductor.
Voltage can be generated by means other than rubbing certain types of materials against each other.

The correct answer is option E.
Explanation:
The pH of the solution is defined as negative logarithm of hydrogen ions concentration in a solution. Mathematically written as:
The pOH of the solution is defined as negative logarithm of hydroxide ions concentration in a solution. Mathematically written as:
The sum of ph and pOH is equal to 14.
pH + pOH = 14
A solution has a pH of 4.20.
Hence, the correct answer is option E.
