an aluminum soda can having a mass of 12.537 g is treated with lithium hydroxide followed by sulfuric and (both in excess) to yield lithium alum dodecahydrate (442.23 g/mol) according to the equation. 2Al (s) + 2LiOH (aq) + 4H2SO4 (aq) + 22H2O (I) -》 2LiAI (SO4)2•12H2O (s) + 3H2 (g)

if the actual mass recovered was 149.3 g what was the percent yield?

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: 2NaOH(aq) + 2Al(s) + 6H2O(l)  2NaAl(OH)4 (aq) + 3H2(g) The heat generated in this reaction helps to melt away grease and the hydrogen gas released stirs up the solids clogging the drain. Calculate the volume of H2 formed at 298 K and 1.1 atm if 1.34 g of Al is treated with excess NaOH...
