Question 1

Metallic aluminum reacts with MnO₂ at elevated temperatures to form manganese metal and aluminum oxide. A mixture of these two reactants is 67.2% mole percent Al. Find the theoretical yield (in grams) of manganese from the reaction of 250 g of this mixture.
◦ 96.6 g
◦ 6.72 g
◦ 193 g
◦ 18.13 g
◦ 87.3 g

Question 2

Determine the theoretical yield of HCl if 60.0 g of BCl3 and 37.5 g of H2O are reacted according to the following balanced reaction. A possibly useful molar mass is BCl3 = 117.16 g mol-1.

BCl3(g) + 3H2O(l) → H3BO3(s) + 3HCl(g)

◦ 132 g HCl
◦ 25.3 g HCl
◦ 56.0 g HCl
◦ 187 g HCl
◦ 75.9 g HCl
