Unformatted text preview: Exam 2 Study Guide: What Concepts/Math Are Most Important? Old Stuff Be able to solve dimensional analysis problems (mostly metric conversions and stoichiometry) Be able to perform density calculations to solve for density, or mass, or volume (d = m/V): memorize equation Know what ions are, how they are formed, and how to calculate the charge on an ion, or how to calculate how many electrons have been gained or lost. Be able to recognize common acids. Be able to name ionic compounds, acids, and simple binary molecular compounds. Be able to write the formula for ionic compounds, acids, and simple binary molecular compounds. Be able to balance eqations (and convert word equations to formula equations). Ch 5 Know the regions of the electromagnetic spectrum; know how to place them in terms of energy, wavelength, and frequency. Given the Rydberg equation, be able to use it to calculate the energy for an electronic transition for hydrogen.* Know that energy of electrons is quantized, which is why they have line spectra. Know that a line in a line spectrum occurs when an excited high energy level electron falls back to a lower energy level....
