Calculate the wavelength of the electromagnetic radiation required to excite an electron from the ground state to the level with n = 5 in a one-dimensional box 39.8 pm in length.
Consider a solution formed by mixing 61.0 mL of 0.100 M H2SO4, 26.0 mL of 0.100 M HOCl, 25.0 mL of 0.200 M NaOH, 25.0 mL of 0.100 M Ca(OH)2, and 10.0 mL of 0.150 M KOH.
an ideal gas with temperature independent Cp = (7/2)R at 15 degrees C and having initial volume 60 m^3 is heated at constant pressure (P =0.1013 MPa) to 30 degrees by transfer of heat from a resivoir at 50 degrees C.
