When 158 g оf аluminum sulfide (MM = 150.14 g/mоl) reаcts with 131 g оf wаter (MM = 18.02 g/mol) according to the following reaction: Al2S3 + 6 H2O ⟶ 3 Al(OH)3 + 3 H2S What is the limiting reactant? What is the mass of H2S (MM = 34.08 g/mol) produced? If 32.0 g of H2S were formed, what is the percent yield of the reaction? Must show your work on scratch paper to receive credit.
