(Answered) Some commercial drain cleaners contain two components

Academics

Some commercial drain cleaners contain two components: sodium hydroxide and aluminum powder. When the mixture is poured down a clogged drain, the following reaction occurs NaOH (aq)+Al (s) + H2O (l)-->NaAl(OH)4 (aq) + H2 (g). The heat generated in this reaction helps melt away grease and the dihydrogen gas released sirs up the solids clogging the drain. Calculate the volume of H2 formed at 20celsius and 750 torr if 3.12 g of Al is treated with excess NaOH.
