answer the questions below, using lt (for is less than), gt (for is greater than), eq (for equal to), or mi (for more information) in the blanks provided. 1. the wavelength of the photon required to promote an electron in the hydrogen atom from the n = 1 to the n = 3 level is the wavelength of the photon required to promote an electron in the hydrogen atom from the n =1 to the n = 2 level. 2. the energy of a photon with a wavelength of 463 nm is the energy of a photon whose wavelength is 722 nm. 3. in order to promote an electron to go to a higher energy level, light with a wavelength that is 400 nm is required.

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.
