Week 16 Resources/ Assets

Please make sure you READ everything on this page or you will miss important details. I will archive past weeks Announcements pages for a limited time only under the Trimester 1 and 2 tabs, if you need to go back to a particular weeks information for any reason. Week 15 in ReviewWe started Chapter 9  Stoichiometry, this past Tuesday, with an illustration concerning a Tollhouse cookie recipe. In our analogy, we considered how to recalculate the amount of ingredients necessary within the recipe, if for some reason, we decided to double it. As an example, if the recipe makes five dozen cookies, and requires 2.25 cups of flour, how much flour would we need if we wanted to bake ten dozen cookies? In another example, if the recipe for five dozen cookies requires one teaspoon of vanilla, how many cookies could we make if we had only 1/3 a teaspoon of vanilla?
This same type of analysis can be performed on reactants and products within a chemical equation. Yet when we actually measure chemicals for the items, we do not use cups or teaspoons, but rather grams or liters (in the case of gases). From the balanced chemical equation, we should be able to determine how much of any ingredient we would need to measure. We were able to get through Sections 9.1 and 9.2. If you are still struggling with the content from 9.2, please take the time to look at the video I uploaded (linked right). Upcoming Week 16 On Tuesday, I will spend a bit more time covering stoichiometric calculations, and then we will move on to Section 9.3  Limiting Reactant and Percent Yield. Please be reminded there will be a quiz on Tuesday covering material from Sections 9.1 and 9.2. To prepare for Tuesday's classes, please make sure you do the following by: Tuesday's class  January 15th:
