Answer: The statement which could possibly not be true is C -" Liquid X can exist as a stable phase at 25°C, 1atm."
Explanation:
Triple point is the point where a substance co-exist as solid liquid and gas. At any point other than the triple point, the substance exist as a single phase substance.
As shown in the diagram, Liquid cannot exist as a stable phase at 1atm( below the the triple point pressure of 2atm) as the liquid can only exist beyond the pressure of triple point.
Answer:
a) Binding Energy = 1084.266 MeV
b) Binding energy per nucleon = 8.28 MeV
Explanation:
Binding Energy,
Where ΔM = Mass defect of Iodine-131
The mass of iodine-131 = 130.906124 u.
Number of protons in Iodine-131 = 53
Number of neutrons in Iodine-131 = 78
Mass of a proton = 1.007276 u
Mass of neutron = 1.008664 u
Total mass of the 53 protons in Iodine-131 = (53*1.007276)
Total mass of the 53 protons in Iodine-131 = 53.39 u
Total mass of the 78 protons in Iodine-131 = (78*1.008664)
Total mass of the 78 protons in Iodine-131 = 78.68 u
Binding Energy = 1.164 * 931.5
Binding Energy = 1084.266 MeV
b) Binding Energy per nucleon
The mass of the nucleon of iodine 131 = 130.906124
Binding Energy per nucleon = 1084.266/130.906124
Binding energy per nucleon = 8.28 MeV
