When conducting an experiment in the lab, a student was able to actually recover 38.5 grams of Zinc Chloride. Using the balanced chemical equation (2 Zn + CuCl2 ---> 2 ZnCl+ Cu) the student predicted that they theoretically should have been able to make 64.9 grams of Zinc Chloride.

What was the percent yield of this reaction?

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
