Anuclear binding energy curve is shown below. the elements heavier than lead may undergo fission. the fission fragments lie near the highest point on the curve, each with a higher binding energy per nucleon. similarly the light isotopes may fuse, the product nucleus also have a higher binding energy per nucleon. both processes release energy. 0 50 100 150 200 250 0 1 2 3 4 5 6 7 8 9 10 average binding energy per nucleon (mev) number of nucleons (a, mass number) binding energy per nucleon 2h 4he 6li 16o 35cl 56fe 98mo 107ag127i 159tb 197au 208pb 238u b b b b b b b b b bb b b b b b b b b b b which process releases more energy per nucleon? 1. both must occur in the same process. 2. fission of uranium 3. fusion of hydrogen

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
