Gain electrons and decrease in size A phase change takes place Net ionic equations demonstrate that many different combinations of reactants can give the same net chemical reaction. Instead, you must begin by identifying the various reactions that could occur and then assessing which is the most probable (or least improbable) outcome. What you have is a mixture of aqueous ions. We can use the data provided to determine the concentration of Ag+ ions in the waste, from which the number of moles of Ag+ in the entire waste solution can be calculated. To predict the product of a precipitation reaction, all species initially present in the solutions are identified, as are any combinations likely to produce an insoluble salt. So far, we have always indicated whether a reaction will occur when solutions are mixed and, if so, what products will form. How do I determine the molecular shape of a molecule?
