A) \[\underline{X}\]
B) \[\Delta {{H}_{f}}(H)=218kJ/mol\]
C) \[H-H\]
D) \[52.15\]
Correct Answer: A
Solution :
\[{{109}^{o}}28\] \[\underline{X}\]atoms KE of \[\underline{X}\] or KE of \[p\pi .d\pi \]atoms \[Xe{{O}_{3}}\] \[Xe{{O}_{4}}\]KE of 1 atom \[3:5\] \[25:9\] \[\Delta {{H}_{f}}(H)=218kJ/mol\] \[H-H\] Minimum amount of energy required to remove an electron from the metal ion (ie. Threshold energy) \[52.15\] \[911\] \[104\]You need to login to perform this action.
