Indenify X in the following nuclear reactions (in the first reaction, n represents a neutron) : (a) `_(1)H^(1) + _(4)Be^(9) rarr X + _(o)n^(1)`, (b) `_(6)C^(12) + _(1)H^(1) rarr X `, (c ) `_(7)N^(15) + _(1)H^(1) rarr _(2)He^(4) + X` |
Answer» Correct Answer - (a) `_(5)B^(9)`, (b) `_(7)N^(13)`, (c ) `_(6)C^(12)` Using the law of conservation of mass number and charge number, (a) Let `._(Z)X^(A)` As `1+9 = A + a :.` As `A = 9` As `1+4 = Z + 0 :. Z = 5` Hence, `._(Z)X^(A)` is `._(5)5^(9)` is `._(5)B^(9)` (b) Let `._(Z)X^(A)` (b) Let `._(Z)X^(A)` As `12+1 = A :. A = 13` As `6+1 = Z :. Z = 7` Hence, `._(Z)X^(A) ` is `._(7)N^(13)` (c) Let `._(Z)X^(A)` As `15+1 = 4 + A :. A = 12` As `7+1 = 2 + Z :. Z = 6` Hence `._(Z)X^(A)` is `._(6)C^(12)` |
