On the basis of the general solubility rules given in the table, write a balanced molecular equation for the precipitation reactions that take place when the following aqueous solutions are mixed. If no precipitation reaction is likely for the reactants given, explain why. (If there is no reaction, type "NONE". Use the lowest possible coefficients. Include states-of-matter under SATP conditions in your answer.)
