Consider the subsequent equations. These may be acid/base or precipitation reactions. If no reaction would take place, simply write no reactions. If a reaction would take place, predict the products, balance the reaction and write net ionic equations.
a) V(ClO4)3 (aq) + Rb2S (aq) -->
b) HBrO3 (aq) + Fe (HCO3)3 -->
c) MgCl2 (aq) + CuSO4 (aq) -->
