The Main Attraction...
The Reaction to Produce Zinc Ammonium Chloride
ZnCl2 (aq) + NH4OH (aq) + NH4Cl (aq) ---->
Zn2(NH3)2Cl2 (s) + HCl (aq) + H2O (l)
&H(rxn) = 152.6 kcal/mol ZnCl2
-------------------------------------------------------------------------------------------------------------
Exp 1-3 Exp 4-6 Exp 7-8
____________________________________________________________
14.0/17.6 13.2/20.2 0.00/0.00
0.7954 0.6535 infinite
1.01 0.76 0.86

row 1: mass of crystals/ filtrate mass
row 2: math
row 3: ratio of ZnCl2/NH4Cl
