Intro
In this breakout, you will solve stoichiometry problems in order recover the uranium stolen from Dr. G's lab. You will need to write down the numbers you encounter along th way so that you know which locker to look in at the end. Good Luck!

Consider the unbalanced equation for the combustion of hexaneC6H14 (g) + O2 (g) --> CO2 (g) + H2O (g) Balance the equation and determine how many moles of O2 are required to react with 7.2 moles of C6H14.
LR: Pb2+, TY: 34.5 g PbCl2, %: 85.3
LR: KCl, TY: 43.5 g PbCl2, %: 35.8
LR: Pb2+, TY: 54.3 g PbCl2, %: 58.3
Lead II ions can be removed from solution according to the equationPb2+ (aq) + 2 KCl (aq) --> PbCl2 (s) + 2 K+ (aq) When 28.5 g of KCl is added to a solution containing 25.7 g Pb2+, a precipitate of PbCl2 forms. The solid is filtered and found to have a mass of 29.4 g. Determine the limiting reactant, theoretical yield of PbCl2, and the percent yield of the reaction.
