A compound formula with brackets is called a coordination complex, and the structure looks like a covalent compound with a transition metal central atom. The bonding that happens is often a hybrid of covalent and metallic bonding. One method of extracting silver from mined ore is by using a complex, K[Ag(CN)2], to make the silver soluble in water. The complex is then isolated to recover the silver using the following chemical equation. 2 K[Ag(CN)2] (aq) + Zn (s) → 2 Ag (s)

One method of extracting silver from mined ore is by using a complex, K[Ag(CN)2], to make the silver soluble in water. The complex is then isolated to recover the silver using the following chemical equation.
2 K[Ag(CN)2] (aq) + Zn (s) → 2 Ag (s) + Zn(CN)2 (aq) + 2 KCN (aq)
a.) 5.00 L of 1.25 M K[Ag(CN)2] is mixed with 215.5 g of zinc. Identify the limiting reactant and determine how many grams of silver are produced.
b.) The quality control chemists at the mine record collecting 672.4 g of silver. What is the yield of this reaction?
