Pluchino – Regents Chemistry The Mole & Stoichiometry – 05 Limiting Reactants Aim: What are limiting reactants? Do Now: You are having a pizza party. Each guest must receive 2 slices of pizza and a can of soda. If you have 2 pizzas, each with 8 slices and 100 cans of soda, how many people can you invite? Limiting Reactant: the reactant that will run out first in a reaction Excess Reactant: the reactant that will still be left over at the end of a reaction ___ Al + ___ O 2 ___Al 2 O 3 If you react 2 moles of Al and 2 moles of O 2 , which is the limiting reactant? Practice: Determine the limiting reactant. __ N 2 + __ H 2 __ NH 3 16 mol N 2 and 18 mol H 2 __ Si 2 H 3 + __ O 2 __ SiO 2 + __ H 2 O 5 mol Si 2 H 3 and 7 mol O 2 ___ Fe + ___ H 2 O ___ Fe 3 O 4 + ___ H 2 You react 190 g of Fe with 100 g of H 2 O. Which reactant is the limiting reactant? How many grams Fe 3 O 4 will be produced?
