![2. Calculate what would be the minimum amount of energy (in joules) necessary to remove a ground-state electron (n - 1) completely from a single hydrogen atom. This process is also known as ionization. To answer this question, think about what value n must be in order to completely separate the electron from the hydrogen atom. (Hint: Use Equation 5 to calculate E, and Ef and then determine AEE E;). Calculate what is the minimum amount of energy (in k]/mole) necessary to ionize one mole of hydrogen atoms. Report your answers to four significant digits.

Beer’s Law Objective : We will explore an application of absorption spectroscopy using calibration curves and Beer’s Law. Use the “LAB : HOW TO…” link from the class website if you need help with how to use balance, Bunsen burner… and such. Introduction: You may write this information in your lab notebook for your own reference. It can’t be cut and pasted. Different solutions have different spectral properties. In this portion of the experiment those properties will be utilized to...
