Question

Consider the following data for zirconium: atomic mass 91.224 mol electronegativity 1.33 kJ 41.1 mol electron affinity kJ 640.1 mol ionization energy kJ 21. mol heat of fusion You may find additional useful data in the ALEKS Data tab. O release Does the following reaction absorb or release energy? O absorb (1) Zr (g) → Zr (g) + e O Can't be decided with the data given. O yes Is it possible to calculate the amount of energy absorbed or released by reaction (1) using only the data above? O no If you answered yes to the previous question, enter the amount of energy absorbed or released by reaction (1): O kJ/mol Does the following reaction absorb or release energy? O release O absorb (2) Zr (g) → Zr (g) + e O Can't be decided with the data given. O yes Is it possible to calculate the amount of energy absorbed or released by reaction (2) using only the data above? O no If you answered yes to the previous question, enter the amount of energy absorbed or released by reaction (2): I kJ/mol

Answer 1

las zrig) - zrt (g) te The amount of energy required to remove an electron from outer most shell of neutral gaseous atou is called Inuizatica energy. Neutral zirconium atau loses electron to form art. Energy is required, energy is absorbed, b) yes. energy. This of zirconium) It is is possible equal to to calculate else Ionizaticu enersy ( The energy absorbed during processo wie Ionization of zuig) is equal to 640.1 kJ mot'. zo (9) - zv19) + é form zr. energy o z is loses electron to absorbed to remove electron Electron I onizatiu energy of zr= Astinity of ar. b) yes. It is possible to calculate dieta energy required for using lle data,

Amount of enersy absorbed for reacticu o is: 4,1 kJ/mol,
