Use the Rydberg equation to calculate the wavelength (in Å) of the photon absorbed when a hydrogen atom undergoes a transition from n = 1 to n = 5.
The ionization energy of hydrogen is reported to be 1.31x10^6 J mol^-1 of H. (1) compute the ionization energy for a single atom of hydrogen.
From the stoichiometry, it's shown that the sodium ethoxide is used in excess. What happens to this excess during work out. (Be specific, write out the reaction that occurs and figure out at what point is it destroyed)

What would happen if you dropped the object into the beaker while using the Archimedes' Principle method instead of submerging the object
An industrial chemist studying bleaching and sterilizing prepares a hypochlorite buffer using 0.150 M HClO and 0.150 M NaClO. (Ka for HClO = 2.9x10^-8.)
Titration of a 20.00 mL sample of a monoprotic weak acid requires 9.86 mL of 0.04899 M NaOH to reach the equivalence point. What is the concentration of the weak acid
find the number of automobiles whose total mass is the same as 1.0 mol blueberries if the mass of an average blueberry
Calculate the millimoles of sodium hypochlorite used in the reaction: 2.3mL of a 5.25% solution (Clorox). Compare this value with the quantity (150mg) of cyclohexanol (MM = 100.158 g/mol) to be used in the reaction
A student is given four solid samples labeled W, X, Y, and Z. All have a metallic luster. She is told that the solids could be gold, lead sulfide, mica (which is quartz or SiO2), and iodine.
Following the instruction for the standardization of sodium hydroxide a student took 3.5 gms of KHP (MWt 204.2g/mol) and titrated the solution formed with the given sodium hydroxide solution.
Use your complete rate law for the dye bleaching reaction to estimate the reaction rate at 25 degrees celcius, if the concentrations of bleach and due are both .10 M.
