"To the physical chemist, the same numbers, the same chemical problems, present themselves in the laboratory and in the study of the stars." Gilbert N. Lewis (1923) Valence and the Structure of Atoms and Molecules Class notes (1-13): https://bricejurban.github.io/CHEM101/ For more Tutorials, Videos, and Problem sets on Stoichiometry: https://chemteam.info/Stoichiometry/Stoichiometry.html Assignments to start this week: HW 10 - Stoichiometry I (to be posted tonight) Assignments next 3 weeks: HW 11 - Stoichiometry II (Limiting Reactants, % yield) HW 12 - Aqueous Solutions, Molarity, Dilutions HW 13 - Equilibrium and Le Chatelier's Principle Activity on Chemical Reactions Reading Quizzes on Chapter 4 and 5 CIC (EDUC 107) Hours: Friday 11AM - 1PM Office Hours (SCNC 314 or Zoom): ﷟HYPERLINK "https://calendly.com/bricejurban/office-hours"By appointment Today's Schedule (2/22): Mole-Mole conversions Mole-Gram conversions Gram-Gram conversions Gram-Atom conversions etc. Tuesday's Schedule (2/27): Limiting and Excess Reactants Percent Yield Stoichiometry With a balanced chemical equation we can figure out: How much product we can produce in a chemical reaction from a given amount of substrate How much substrate we need to produce a certain amount of product How much substrate we need to react with another substrate. How much excess reagent will remain at the end of a reaction (Next Tuesday) What is the percent yield of a reaction (Next Tuesday) If we have moles of a reagent and need moles of a different reagent this is a one-step calculation. If we have grams of a reagent and need moles of a different reagent this takes two steps to calculate. If we have moles of a reagent and need grams of a different reagent this takes two steps If we have grams of a reagent and need grams of a different reagent this takes three steps
If we have grams of a reagent and need grams of a different reagent this takes three steps If we have a starting amount in atoms, and/or need the final amount in atoms we can find this too. Use this stoichiometry map as a guide before you start any calculations!
