11 1 Activity Precipitation Reactions When a solution of leadII nitrate is mixed with a solution of potassium chromate a yellow precipitate forms according to the equation PbNO 3 2 . Stoichiometry. . Limiting and Excess Reactant. Standards. 3.3c. A balanced chemical equation represents the conservation of atoms. The coefficients in a balanced equation can be used to determine mole ratios in the reaction.. (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 . with a Twist. Given the density of oxygen is 1.439 grams per liter, how many liters of oxygen gas can be produced if 15.0g of mercury (II) oxide are heated to produce mercury and oxygen gas?. Episode 803. Limiting Reactant. Limiting Reagent. The . reactant. that is totally used up during the chemical reaction. Limits. the amount of . product. produced . Excess Reactant. Excess Reagent. The . reactant. Consider the balanced equation for the production of ammonia:. N. 2. . 3. H. 2. .  . 2. NH. 3 . If you have 2 moles of nitrogen and 3 moles of hydrogen, which reactant will be used up?. How much ammonia will you be able to make?. If it takes 500 bricks and 1000 boards to make a house, how many houses can you make from 1600 bricks and 2000 boards?. 2 houses, there are enough bricks for 3.2 houses. but only boards for 2 with our plans (reaction).. Chocolate Chip Cookies. Cookie Recipe . 1.5 c sugar. 1 c. butter. 3 eggs. 2.25 c. flour . 2 c. chocolate chips . makes 25 cookies. Using the following recipe, complete the questions. . .

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. Stoichiometry Unit Objectives. Solve reaction stoichiometry problems:. Mole- Mole. Mass – Mole. Mass-Mass. Mass Volume. Introduction. In any stoichiometry problem we start with a given quantity of a reactant or product. We use conversion factors and unit analysis to determine the quantities of the unknowns that react or form.. 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; . Evidence of a chemical reaction includes:. Chemical Reaction. 1) Change in color / light. 2) Change in temperature. Evidence of a chemical reaction includes:. Chemical Reaction. 1) Change in color / light. Limiting reactants. Percentage yield. Stoichiometry Problems. How many moles of KClO. 3. must decompose in order to produce 9 moles of oxygen gas? . = 6 mol KClO. 3. Problem: X mol. KClO. 3. .
