WileyPlus Make sure to register on WileyPlus Instruction video on registration found at: https://www.wileyplus.com/WileyCDA/Section/id-406168.html Lecture notes available on the site Online textbook plus other resources Practice assignments that are not worth marks but you are strongly encouraged to do

Labs Buy a lab manual this week at the Petrified Sole Bookstore (in the basement of the Bulman Student Centre). Bring it to your first lab next week. Attend your SCHEDULED first lab, during the week of Monday Sept. 12th to Friday Sept. 16th. All lab sections are full, so you cannot attend at a different time. You must attend this first lab in order to find out which experiment or workshop you will be doing the following week. (Not everyone will start with Experiment #1.) Questions? Contact Theresa Baran Lab Coordinator uwintrochem@gmail.com

To do well in the course Read ahead in your textbook – don’t get behind. Do LOTS of problems!!!!!!!! Work together! Problems will be assigned from the textbook plus feel free to do more on your own. Also – weekly assignments will be provided on WileyPlus Feel free to contact me and Theresa, we will be available by e-mail and have office hours!!!

Chapter 1 Quick review, you are expected to know this material from high school. Please read Chapter 1 thoroughly for a full review. Also, work on the Chapter 1 Assignment (Due Friday not for marks) on the WileyPlus site. Textbook questions: 1.3, 1.5, 1.7, 1.9, 1.11, 1.19, 1.23, 1.25, 1.27, 1.31, 1.33, 1.35, 1.79, 1.85, 1.87

Measurement in Chemistry Smallest fundamental unit of a substance is an atom Atoms bond together through ionic or covalent bonding to produce molecules Atoms and molecules are extremely small, so are measured in moles. 1 mole = 6.022 x 1023 molecules or atoms Called Avogadro’s number The mass of 1 mole of atoms is the molar mass Molar masses given on periodic table

Periodic Table What is the mass of 2 moles of Fluorine? How many moles in 13 g of Chromium? Molar mass in g/mol

Concentrations Concentrations can be mass per volume or moles per volume In a gas, use m3 as unit of volume (mol/m3) In liquids, use L or mL as unit of volume Moles per litre: Molar (M) Concentrations can be moles per unit mass Moles per kg: Molal (m) See table 1.1 (page 9) for magnitudes Commonly see M (mega), k (kilo), m (milli) and μ (micro)

Dilutions Say we have CaCl2 solution with a concentration of 50 mM in 100 mL of water What is the concentration in 500 mL of water? What are the final concentrations in moles per litre of Ca2+ and Cl- ions?

Chemical Reactions and Stoichiometry Stoichiometry: study of amounts of materials produced and consumed in chemical reactions Consider the reaction with 4 mol of H2 and 4 mol of O2: 2 H2 + O2  H2O How many moles of H2O should be produced if the reaction goes to completion and is completely efficient? If 3.2 moles of H2O are formed, what is the percentage yield for the reaction?

Significant figures How many significant figures do the following numbers have (calculate as necessary)? 35 35.0 0.687 3.54 x 10-3 M 6.02 M + 75 mM 5.5 mol 10.5 m3
