Why doesn’t the reaction: Br2(aq) + 2NaCl(aq) → Cl2(aq) + 2NaBr(aq) occur? In other words, why don’t the two Br atoms stop sharing an e pair with each other to exist as Br2 and each take an e from the available two Cl ions instead? Answer with respect to the relative E. A. values for Cl and Br. /2

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
