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.

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
