FOR FULL CREDIT, SHOW DETAILED CALCULATION SETUPS. REMEMBER TO FOLLOW THE SIGNIFICANT FIGURES CONVENTION, AND TO SHOW MEASUREMENT UNITS FOR EACH QUANTITY. 1. Based on the empirical formula you determined for copper chloride, complete and balance the following equation for the major reaction in this experiment. 5Al(s)+3Buff(aq,blue)5AlCl3(aq)+Cu(s) 2. Using YOUR equation from question 1, and YOUR data from this experiment, calculate the mass (in grams) of Al that reacted with the copper chloride in the lab. Show each step of the calculation.
