L07 Chem 151 Study Guide - Midterm Guide: Molar Concentration, Lewis Structure, Photon
Document Summary
Experiments 0-4: materials covered in lab manual, lecture, course content videos, exercise sets, and quizzes, chemistry background pertaining to the experiments, understanding of experimental procedures and observations, laboratory skills and equipment involved, laboratory safety. Experiments 0 and 1: check in, chemical nomenclature, and periodic properties. Naming simple cations: cations containing a single atom= same name + ion, ex: li+=lithium ion, be 2+=beryllium ion, metal cations with multiple stable oxidation states: Penta- 5: hexa- 6, hepta- 7, octa- 8, nona- 9, deca- 1, ex: cuso4 5h2o= copper (ii) sulfate pentahydrate. Naming covalent compounds: nonmetals only and no polyatomic ions, name the less electronegative element + the more electronegative -ide. In the formula, usually the less electronegative one goes first: ex: co= carbon oxide, greek prefixes are used to distinguish numbers of atoms of one or both elements, ex: co2= carbon dioxide, so3= sulfur trioxide, n2o4= dinitrogen tetraoxide.
