1. (a) Write balanced molecular equations for the following potential precipitation reactions. Indicate the states of reactants and products [(aq) or (s)]. (b) In those cases where a precipitate forms, write the net ionic equation. If there is no reaction, state "No reaction." (ii) MgCl2(aq)+Hg2(NO3)2(aq) (iii) NaOH( aq) +Ni(CH3CO2)2 (aq) (iv) Sr(ClO4)2 (aq) +K2CO3 (aq)
