Consider the combination reaction between aluminum metal and liquid bromine (d = 3.1028 g/mL). Also consider that you have 38.4 g of aluminum metal and 40.6 g of bromine liquid. For this reaction AHrxn = -526 kJ/mol. If you were able to measure 15.5 kJ of heat being dissipated from this reaction, what would you expect to be the percent yield based on the heat generated? Hint: Find the limiting reagent before calculating the theoretical yield of the reaction.

1. How much heat is needed to raise the temperature of 1.50 g of aluminum metal from 23.2 °C to 30.5 °C? (Specific heat capacity of aluminum is 0.90 J/g-K). 2. Given the following thermochemical equation: DH = -1107 kJ How many kJ of heat are released when 15.75 g of Ba(s) reacts completely with oxygen to form BaO(s)? 3. Mothballs are composed primarily of the hydrocarbon naphthalene (C10H8). When 1.25 g naphthalene is burned in a bomb calorimeter, the temperature rises from 25.25...
