Balancing Hints:. Balance the metals first.. Balance the ion groups next.. Balance the other atoms.. Save the non ion group oxygen and hydrogen until the end.. Balance . the following equations;. __Ca . (aka limiting reagent). Excess Reactant. Theoretical, Actual, and Percentage Yield. Limiting Reactant. (aka limiting reagent). Limiting reactant. : The substance you run out of first, that is consumed first--The reactant that . Chemistry. Ms. . Piela. Stoichiometry. The quantitative study of reactants and products in a chemical reaction. Chemical reactions give info about how molecules combine, and can be used to determine amounts of substances that form. Stoichiometry. !. So far. In all our reactions, we assume both reactants get used up. We assume both reactants provided are pure. We rarely see these two.. Limiting reagents. Percent Purity. Percent Yield. vocab. Limiting reactant- the one that runs out first, limits the amount of product that can be made. Excess- the one with reactant leftovers, not used up completely. What it looks like. C + O. 2. = CO. Yes…it’s still stoichiometry…. Think about making grilled cheese…. To make a . decent . grilled cheese sandwich, you need two pieces of bread, 2 pieces of cheese, and 1 pat of butter. Write an equation that describes making a grilled cheese sandwich. .

Advanced Stoichiometry Chapter 9, Section 2 (pages 312 – 318) Problem Set E (p. 314 # 1 – 3) Problem Set F (p. 317 # 1 – 3) Terms to Know and Understand: Limiting Reactant – the substance that controls the quantity of product that can form in a chemical reaction. 9-3. 9-3 Learning Targets. Identify the limiting reactant in a chemical equation. Identify the excess reactant and calculate the amount remaining after the reaction is complete. Calculate the mass of a product when the amount of more than one reactant is given. III.. . Limiting Reactants. . A. Why do reactions stop? Are all reactions 100% efficient?. Reactions might . stop. for a number of reasons including: . consumption. of one or multiple reactants; occurrence of side reactions; . LIMITING REAGENT PROBLEM:. A strip of Zn metal weighing 2.00 . g. is placed in an aqueous solution containing 2.50 . g. silver nitrate causing the following reaction to occur:. Zn (. s. ) + 2 AgNO.
