Molten salts When electricity is applied to a molten binary salt, the cation will be reduced and the anion will be oxidized. The electrolysis of CaBrz (), for example, produces Ca(s) at the cathode (from the reduction of Ca2+) and Br2(1) at the anode (from the oxidation of Br"). If more than one cation is present, only the one with highest reduction potential will be reduced. Similarly, if more than one anion is present, only the one with the highest...

Questions 1 and 2
Ionescent molten lava. Living LIVE II only a limited portion of the Earth's temperature range. In fact, the activities of life are possible only in the range from around 0°C (the freezing point of water) to 100°C (the boiling point of water). Of course, there are always exceptions to this rule. In some instances, life can survive at temperatures well below freezing and some organisms are adapted to very high temperatures. PROCEDURE (GENERAL EXPERIMENTAL SET-UP) Just...

Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...
