Question

aluminum sulfide and water react to form aluminum hydroxide and hydrogen sulfide gas. suppose 128.00 g of aluminum are added to 154.45 mL of water(d=1.00 g/ml). Answer the following questions.

a).before the reaction, how many water molecules are present in the reaction mixture?

b) when the reaction is finished. what mass, in g, of aluminum hydroxide can theoretically be produced?

c) limiting reactant?

d) mass in grams of remaining excessreactant if the theoretical yield of aluminum hydroxide is obtained?

e)if the percent yield is 87.6% under these conditions what is the actual yiel of product aluminum hydroxide?
