Equations (work alone) For each one of the four cations, write balanced equations for each reaction that occurs. For convenience you may write either NH3 or NH4OH for ammonia. Since the "active ingredient" in combo is NH4OH, a reaction with combo is the same reaction as with NH4OH. If no change occurs, write NA. See examples of various equations in the procedure. Reactions involving the magnesium ion Mg+2 with NaOH: small amount: excess: Mg+2 with NH4OH (NH3): small amount: excess: Mg+2 with K4[Fe(CN)6]: Mg+2 hydroxide precipitate and HNO3: Mg+2 complex ion and HNO3: Reactions involving the iron(III) ion Fe+3 with NaOH: small amount: excess: Fe+3 with NH4OH (NH3): small amount: excess: Fe+3 with K4[Fe(CN)6]: Fe+3 hydroxide precipitate and HNO3: Fe+3 complex ion and HNO3: Reactions involving the zinc ion Zn+2 with NaOH: small amount: excess: Zn+2 with NH4OH (NH3): small amount: excess: Zn+2 with K4[Fe(CN)6]: Zn+2 hydroxide precipitate and HNO3: Zn+2 complex ion and HNO3: Reactions involving the aluminum ion Al

Definition 3.8 Let S be a set that is totally ordered by ?. A binary search tree on S is B1. The empty tree, or B2. a single vertex $r \in S$. In this case, $r$ is the root of the tree. R. If $T_1$ and $T_2$ are binary search trees with roots $r_1$ and $r_2$, respectively, and if $a \le r$ for all nodes $a \in T_1$ and $r \le b$ for all nodes $b \in T_2$, then the tree is a binary search tree with root $r$.
