10.00 g of aluminum sulfide and 10.00 g of water react until the limiting reagent is used up: Al2S3 + 6H2O → 2Al(OH)3 + 3H2S

a) Which is the limiting reagent?

b) What is the maximum mass of hydrogen sulfide that can form?

c) How much excess reagent remains after the reaction is complete?

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next
