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.
The difference between an element and a compound is that an element is composed of only one kind of atom while a compound is composed of at least 2 kinds of atoms. The properties of an element and the compound the atoms has to form are different physically and chemically.Example of element are O and H, while compound examples are H2O and H2O2.
