Question 6.
a) Photons of incoming radiation have an energy of E = 2500 kJ/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(e) + 8 H2O(g) AcH°= -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()) undergoes complete combustion?
