Result of bombardment of metal anode with high energy electrons.

Question

Question 6. a) Photons of incoming radiation have an energy of E = 2500 kl/mol. Calculate the wavelength (in nm) of those photons. b) Would photons from part (a) be able to ionize a Be3+ ion if the electron is found in n=3? Show a calculation to support your answer. c). Consider the following balanced combustion reaction: C7H16(1) + 11 O2(g) 7 CO2(g) + 8 H2O(g) A:H°= -1160 kJ/mol If the density of C7H16(1) is 0.68 g/mL, how much heat (in J and scientific notation) is released if 125 mL of C7H16(1) undergoes complete combustion?

Mystery element X has the electron energy levels shown in the figure below, in which E₁ = -9.1 eV, E₂ = -4.2 eV, and E3 = -2.8 eV. The dashed line is not an energy level, but rather just shows the location of zero energy. n = 00 0 eV n = 3 E 3 n = 2 E 2 n = 1 E₁ (a) How much energy does it take to ionize, or remove, an electron that is in the ground state of this atom? 9.1 eV (b) There is one transition in the emission spectrum that will not be observed in the absorption transition. What is the (positive) energy of this transition? 7 X ev (c) What is the wavelength of the photon emitted in this transition? 1970 x nm (d) Now consider the absorption spectrum. What is the energy of the transition in the absorption spectrum that has the shortest wavelength? HINT: Identify the transitions that occur in the absorption spectrum and then think about how energy and wavelength are related.
