An electron in the 2nd excited state is trapped in a 1-d infinite square well with edges at x-o and x 0.9 nm. a. sketch the wavefunction of the electron. b. calculate the energy of the electron. c. what is the probability of finding the electron between 0 and 0.3 nm? d. the energy of the sides of the well is lowered from infinity to about 10 ev. without calculating, describe how the energy and wavelength of the electron will change and explain why these changes will occur based on the wavefunction.

Can anybody me with this? ? (picture included.)

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
