Aluminum metal burns in liquid bromine forming aluminum bromide in a reaction much more spectacular than aluminum burning in oxygen. In a particular reaction, a 5.000 g sample of aluminum reacts with 13.00 mL bromine (d = 3.103 g mL^-1). What is the mass of aluminum bromide produced in the reaction? What is the mass of the reagent in excess that remains? The balanced equation is: 2AI(s) + 3B_r_2(I) rightarrow 2AIB_r_3(s) balanced (molar masses AI = 26.98 g mol^-1 and...

A common primary battery for pacemakers is the lithium–iodine cell. The negative electrode is lithium metal, the positive electrode is a paste made with I2 and a small amount of polyvinylpyridine (PVP), and the separator is the ionic salt LiI. The overall reaction is 2Li + I2 « 2LiI(s) Write out the half-cell reactions and using the DG°f,LiI = -270.3 kJ mol-1 calculate the equilibrium potential and the theoretical capacity in A·h·g−1. You may treat the positive electrode paste as...
