THE PENNSYLVANIA STATE UNIVERSITY Department of Chemistry A Guide for Summer Review for CHEM 110 Chemical Principles 1 Success in chemistry depends not only on knowledge of chemical principles but on mathematical skills as well A solid foundation of algebra is essential Students entering CHEM 110 should have the ability to solve word problems ie translate words into algebraic expressions relate functions and graphs rectangular coordinates manipulate logarithmic expressions and solve equations involving logarithms manipulate algebraic fractions manipulate algebraic expressions involving exponents and radicals solve quadratic equations use a pocket calculator to complete numerical calculations involving the above concepts understand and manipulate standard units of physics and chemistry including unit conversions and dimensional analysis 908994P N What is expected in the way of chemistry background is really better described as knowledge or understanding as opposed to skill It is expected that a prepared student will know or knew and be able to review fairly quickly the following 1 The meaning of the terms atom molecule element compound mixture ion electron proton neutron metal and nonmetal 2 What the periodic table is and where to find metals nonmetals and inert gases 3 The symbols for the following elements hydrogen helium neon argon lithium sodium potassium magnesium calcium aluminum iron copper zinc silver mercury chromium manganese boron carbon silicon nitrogen phosphorus oxygen sulfur uorine chlorine bromine and iodine 4 The symbols or formulas for and the charges on ions such as sodium ion magnesium ion iron III ion copper II ion uoride ion chloride ion bromide ion iodide ion nitrate ion sulfate ion carbonate ion bicarbonate or hydrogen carbonate ion hydroxide ion ammonium ion and hydronium ion 5 Formulas for compounds such as water ammonia hydrochloric acid sulfuric acid sodium hydroxide sodium bicarbonate sodium sulfate calcium chloride ammonium chloride and zinc nitrate What an acid base and salt are What a chemical equation is and how to balance simple ones How to calculate molecular mass from atomic masses What a mole is in chemistry and how it is used to solve problems relating amount of product to amount of reactant 10 What is meant by the pressure of a gas and how it varies with changes in temperature and volume 509080 Although all of these items are encountered in CHEM 110 it is assumed that they have been encountered and understood previously and therefore little time is devoted to explaining them anew Students who do not recognize these basic aspects of chemistry should realize that this indicates an insufficient background and portends trouble Such students should take CHEM 101 before CHEM 110 Students who have covered much of this material previously but who feel unsure about their preparation should consider enrolling in CHEM 108 the lcredit supplement to CHEM 110 which devotes additional time to fundamental concepts and problem solving skills Approved by the Department of Chemistry February 2009
