Given the reaction: 6 NaOH + 2 Al —-> 2 Na3AlO3 + 3H2 How many miles of hydrogen can be produced from 6.9 moles of aluminum

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
