Limiting reactants

The limiting reactant is the reactant that runs out first or the one that produces the least amount of products Common sense example. John buys 8 hotdogs. How many products can he make if he has an unlimited supply of buns? Jill buys 10 buns. How many products can she make if she has an unlimited supply of hotdogs? Hotdog + bun  yummy What is the maximum number of yummies could you make with 8 hotdogs and 10 buns? Why? Were limited by the number of hotdogs;therefore, the hotdogs were the limiting reactant. 8 yummies

Zn (s) + HCl (aq)  H2 (g) + ZnCl2 (aq) 2 If 25.0 grams of zinc was reacted with 25.0 grams of hydrochloric acid(36.46), how many grams of hydrogen gas could be produced? What is the limiting reactant? Zinc + hydrochloric acid  hydrogen + zinc chloride Zn (s) + HCl (aq)  H2 (g) + ZnCl2 (aq) 2 25.0 g 25.0 g ? g Really 2 separate stoich problems. 0.771 g H2 Which one is smaller? 0.691 g H2 HCl is the L.R. because it produces the least amount of product.
