If 7.56 g of iron metal are placed with 0.100 moles HCI, hydrogen gas and iron (II) chloride are produced. Which reactant is limiting, and how much (grams) excess of the other reactant is there?
Calculate the grams of each product. Also determine the % yield if 5.25g FeCl, are produced in the lab.

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
