The mass numbers for two isotopes are unequal because they have different numbers of

<u>Answer:</u> It is so because they have different number of neutrons.
<u>Explanation:</u>
Isotopes are defined as the chemical species which have same number of protons but differ in the number of neutrons.
They have same atomic number but different atomic mass.
<u>For Example:</u> are the three isotopes of carbon.
The number of protons in all the three isotopes is same which is 6 and the number of neutrons in the three isotopes are 6, 7 and 8 respectively.
Hence, it is so because they have different number of neutrons.

Answer:
Explanation:
The relation between Kp and Kc is given below:
Where,
Kp is the pressure equilibrium constant
Kc is the molar equilibrium constant
R is gas constant
T is the temperature in Kelvins
Δn = (No. of moles of gaseous products)-(No. of moles of gaseous reactants)
For the first equilibrium reaction:
Given: Kc = 0.50
Temperature =
R = 0.082057 L atm.mol⁻¹K⁻¹
Δn = (2)-(3+1) = -2
Thus, Kp is:
