Week 30

Week 30 was more continued studying of stoichiometry.  Monday we all tried each other's cookies that we made over the weekend.  Each of us had a different recipe that ended up having either too much, or too little of a certain ingredient.  These fluctuating amounts created disgusting cookies, except for one group's that were perfect.  One of the cookies had way too much salt, some had too much flour, and a few other different amounts of ingredients.  This cookie experiment relates to equations and balancing.  If the proportions are not exact, the result will not end up being what was planned.  There has to be the correct amount of each element to react properly with others.  As we continued the week, we continued with stoichiometry.  We really focused on the importance of proportions to predict the products that would be yielded in a reaction.  With these proportions, we also focused on the limiting and excess reactants in the reaction.  Depending on which reactant was in excess or limited would play a major role in the products.  We also learned about percent yielded, which is the percent of products yielded compared to the theoretical amount that could result from the reaction.  I feel very confident with the assessment we took at the end of the week since I really grasped the concept.
