Balance the following skeleton reaction(if the coefficient is 1, put 1; if the coefficient is 0, put 0) and identify the oxidizing and reducing agents. For the oxidizing and reducing agent, enter numbers and +/- directly for superscripts and subscripts. (eg. enter HCO3- for HCO3-, Cu2+ for Cu2+) P4(s) HPO32–(aq) + PH3(g) [1]P4(s) + [3]H+(aq) + [4]H2O(l) [5]HPO32-(aq) + [6]PH3(g) + [7]H+(aq) + [8]H2O(l) (acidic) Oxidizing agent: [9] Reducing agent: [10]

A metal bromide, MBr2, is converted to a molten form at high temperature. Electrolysis of this sample with a current of 5.00 A for 50.0 seconds results in deposition of 0.0847 g of metal M at the cathode. The other product is bromine gas, Br2(g), which is released at the anode. Determine the identity of metal M. (MTS 7/21/2020)
