Some commercial drain cleaners contain two components: sodium hydroxide and aluminum in the form of a powder. when the mixture is poured down a clogged drain, the following redox reactions occurs: 2naoh(aq) + 2 al(s) + 6h2o(l) → 2naal(oh)4(aq) + 3 h2(g) the heat generated in this reaction melt away grese and the hydrogen gas released stirs up the solids clagging the drain. calculate the volume hydrogen gas formed at 20. ºc and 750. torr if 3.12 g of al is treated with excess naoh.
