Write a balanced chemical equation to describe this reaction b. where Eq (6) produces a soluble cuprous complex which feeds Eq (7), an electrochemical reaction. Then if we were to combine the two in water, then to evapourate the mixtrue down to a mixture of solid copper(II) chloride and potassium chloride. Samuel F. In many cases a complete equation will be suggested. Then if we were to heat the mixture and evapourate off Cu2Cl4 vapour (this is the most likely gas state form of copper(II) chloride) then the radioisotope would be distributed between the copper and potassium chlorides. In the net ionic equations, we are not include the spectator ions in the equations. { "16.01:_Solute-Solvent_Combinations" : "property get [Map
