OR Flash player updated? Grade postings: Contact Dr. Frerichs Answering questions: Contact Dr. Gulde or Dr. Frerichs Registering: View Video on UB Learns, then contact Dr. Frerichs Optional Assignments: (no credit) (Both HIGHLY RECOMMENDED!) Intro to Mastering Chemistry Chemistry Primer Hints : Some questions have them, able to earn extra pts if answered correctly• If answer incorrectly, can lose points, but if they help you answer the overall question then you usually earn more points than you would lose if you didn’t answer the question• No points lost if look at them HIGHLY recommend using when available You get 6 attempts at each question Suggestions: Each assignment ~2-4 hrs Work the problems pertaining to material learned in that day’s lecture If can’t answer in 10 minutes, move on and seek help-2CHE-101 Lecture Outline Chapter 1Chapter 1: Matter & MeasurementWhat is chemistry? Chemistry - ______measuring__________________ and analyzing _________matter__________ and how it ____changes____________________ Also interested in the __energy__________________ associated with these change Matter - has _____mass______________ and takes up _____space_______________ Atom – ________smallest__________________ building block of matter Molecules – ___________2 or more___________________ atoms bonded togetherMATERIAL TO LEARN ON YOUR OWN Chapter 1 contains many definitions that describe matter. I do not have time to cover them inlecture. A Pre-recorded lecture is located on UB Learns for you to watch and fill in your notes, Prior to your next lecture.
