Nothing will precipitate. K sp for MgF 2 is 6.4 x 10 -9 . Br 2 in aqueous acid. The coefficients for MnO 2 and Br- are both 1. The coefficient of Br 2 is 2.
Water is consumed as a reactant.
Electrons flow from the cathode to the anode. Suppose an electrolytic cell is operating at 0.50 amps. The ratio of neutrons to protons in a nuclide is an important factor for the stability. An unstable nuclide will undergo some form of radioactive decay. Nd is an alpha emitter.
