Student Name:AP ChemistrySummer Work PacketWELCOME to AP chemistry! The AP curriculum includes all the topics and the labs that we need to completebefore the 2019 AP test. All of you will find AP chemistry to be challenging and some of you will find it to bedown-right hard. There is a lot to cover and while we can do it, we will all need to work very hard. You shouldexpect this class to be SIGNIFICANTLY more difficult than your first chemistry class. This means that wecannot slow down if you don’t understand a topic. You need to make sure that you are staying up with allassignments and coming in for help if you need extra help.One stereotype of chemists is that they lead uninteresting lives hidden in a laboratory. Chemistry can lead to veryinteresting and exciting careers in research, medicine, engineering, law, etc. Here are a few examples of famous chemistswho do not fit the stereotype:Chaim Wieizmann – First President of IsraelKnute Rockne – legendary football coach of Notre DameMario Molina – co-discovered that fluorocarbons could destroy the earth’s ozone layerMarye Anne Fox – former chancellor of UCSDSamuel Massie Jr. - the first African American professor at the U.S. Naval AcademyLinus Pauling – winner of the Nobel Prize in both Chemistry AND Peace.Dream about the day when your name might be added to this kind of list!A hallmark of AP chemistry is the opportunity to perform chemistry experiments. You will have lots of hands onlaboratory experience with chemicals, glassware, and instruments which will allow you to experience the theoreticalconcepts of the discipline. Most students find that being in the lab and “doing” things is the most exciting part of thecourse.All students taking AP science courses are required to complete a review packet prior to the start of the course.Each course’s packet is designed to help the student review material that was learned in prerequisite scienceclasses. The material is necessary for the student to successfully begin the AP course that he/she has chosen. Apretest will be administered the first day of class to assess the students’ knowledge of the science concepts coveredin the packet. This pretest will not be reflected on the marking period grade, however the work done in the summerpacket will be graded.The teacher will personally consult with the parent/student to discuss their future in the class if:1. the student does not show adequate knowledge of the subject material covered on the pretest.2. the student does not complete the summer work packet by the first day of class.3. the student does not hand in the summer work packet on the first day of class.AP Chemistry will be taught with the assumption that all students are taking the AP exam in the spring. Althoughsome students may not take the test due to circumstances that can be discussed later.If you have any questions, please e-mail either Mr. Dellamorte at: adellamo@psd202.orgWe need to use our class time effectively so the goal of this summer packet is that you will have reviewedmuch of the material from your first chemistry class. We will not just review material from before.1

This assignment should be completed and ready to turn in by the FIRST day of class.We will have take-home work over all academic year breaks (fall, Thanksgiving, winter, and spring) this will be tocover and review material without wasting class time.WHY DO WE HAVE TO DO SUMMER WORK?- It is a review of basic content covered in chemistry I, which you may not have seen for over a year.- It provides the necessary fundamentals you will need to be successful in AP chemistry. To not do thesummer assignment or to do it poorly is to seriously endanger your prospects of being successful in APchemistry.- There will not be enough time before the AP exam to cover the necessary content without this headstart.Students are encouraged to work together to complete the summer assignment. THAT DOES NOT MEANCOPY! You should spread the out the following assignments over several weeks. Do not try to cram them intowards the end of the summer or you will get stressed out before school starts.AP Chemistry First Week Test – will consist of the following areas, be cool be prepared!1) polyatomic ions (including name, symbol, and charge)2) Variable charges for transition metals3) Naming Acids4) Naming Ionic Compounds5) Naming Covalent CompoundsSO WHAT IS THE SUMMER WORK? All work should be done neatly and clearly on paper and organized inthe order it was assigned. All work for every problem including units throughout is necessary for AP. This is anexpectation on the AP exam in the spring and we want to get into the good habit early--–Part 1 – Why are you taking this course?A short concise paragraph answering the following questions (1) Why are you taking this course?And (2) What do you hope/expect to get out of the course?Part 2 - Memorize Charges of Common IonsIf you know me or had me before you know I am not a big memorization person however this is a vitalpart of AP chemistry. They will not give you an ion chart so it is essential that you have this done priorto school beginning. I suggest flash cards and lots of practice.Part 3 – Read, Outline, and Review Pages in BookYou must outline each chapter, marking areas that you are unfamiliar with or feel you might struggle withso you know what to come back to and study.GET USED TO READING! This is ABSOLUTELY necessary for AP Chemistry!Success in chemistry is directly related to problem solving. The more problems you do, the more you willlearn! You are encouraged to set up a study group!College level work requires reading material written in academic language. It takes consistent practice toadapt to this (just as it takes practice to become used to Shakespearean English). It might be helpful to previewsome concepts by using a simple, easy to read text such as The Cartoon Guide to Chemistry (Gonick &Criddle) or even Chemistry for Dummies (Moore). Look in the library, or check Amazon (used books, ofcourse).- Read chapters 1-3 in your textbook (Zumdahl and Zumdahl).Use the questions and exercises to check yourself as you read.- Complete the following problem sets. This material should be largely review; refer to your textbook as needed.2

Answers to certain problems can be found in the back of the textbook. Some problems are more challenging, butthey are all solvable.- Chapter 1: Matter and Measurement Everything in this chapter is basic but important. You may skim through if you find it easy.Learn all of table 1.4 (S.I. Base units) except Luminous intensity, and table 1.5. Make sure you know the names of the common devices in figure 1.20 on page 17. Pay particular attention to rules for significant figures.Chapter 1 problemsRequired text problems (pg 32) 29 - 81 odd- Chapter 2: Atoms, Molecules, and Ions Simple review. All sections are important.Chapter 2 problemsi. Required text problems: 31-37, 41, 47-79, 59,65,67,69,107,109 only odd problemsChapter 3 problemsi. Required text problems: (pg 119) 1 only oddproblemsPart 4 – Read through the various handouts regarding work ethic and requirements at the end of thispacket!!Part 5 – LAST PART – Come to school in August with your COMPLETED Summer packet (See Parts 1-3& the nomenclature worksheet at the end of this packet.)3

Sample of a chapter outline:AP ChemistryChapter 1 Outlinea) The Study of Chemistryi) Matter: the physical material of the universe; has mass and occupies spaceii) Property: any characteristic that allows us to recognize a particular type of matter and todistinguish it from other typesiii) Element: basic substance of matter; about 100 different types; can’t be broken down intosimpler substancesiv) Atom: tiny building blocks of matter; each element has its own kind of atom (1)Composition: summary of the kinds atoms in a particular type of matter (2)Structure: the arrangement of the atoms in a particular type of matterv) Molecules: two or more atoms joined in specific arrangements/shapesvi) Goal of chemistry: explaining macroscopic behaviors using submicroscopicdescriptionsMOST IMPORTANT POINT TO ME FROM THIS SECTIONb) Classifications of matteri) Physical State, aka states of matter(a) Gas(b) Liquid(c) Solidii) Pure substance: matter that has distinct properties, uniform composition from sample tosample(1) Elements: contain only 1 type of atom(a) 116 known elements(b) Chemical symbols arranged in periodic table(2) Compounds: contain 2 or more kinds of atoms, but only 1 kind of molecule; (a)Can be decomposed into simpler substances by chemical means(b) Have different properties from their constituent elements(c) Law of Definite Proportions (aka constant composition)—Joseph Proust( 1800)—the elemental composition of a pure substance is always the same iii)Mixtures: combinations of 2 or more substances in which each substance retains itschemical identity(a) May be heterogeneous: composition, properties and appearance varythroughout(b) May be homogeneous: uniform throughout; also known as solutionsMOST IMPORTANT POINT TO ME FROM THIS SECTIONc) Properties of Matteri) Every substance has a unique set of properties.ii) Physical properties: can be measured without changing identity or composition ofsubstance4

(a) Color, odor, density, melting point, hardness, etc.iii) Chemical properties: describe the way a substance may change (react) to form othersubstancesiv) Intensive properties: do not depend on amount of substance(1) Temperature, melting point, density(2) Can be used to identify substancesv) Extensive properties: depend on the quantity/amount of substance(1) Mass, volumevi) Physical changes: physical appearance of substance changes, but not its composition(1) Changes of statevii) Chemical changes (aka chemical reactions): substance transformed into a chemicallydifferent substanceviii) Separation of mixtures by taking advantage of the different properties of thecomponents(1) Filtration: separation of a solid from a liquid by passing it over a porous medium(filter paper(2) Distillation: separation based on different boiling points of substances(3) Chromatography: separation based on different abilities of substances to adhere tothe surfaces of various solidsMOST IMPORTANT POINT TO ME FROM THIS SECTIONd) Units of Measurementi) Quantitative Measurements: associated with numbers ii)SI units:Physical QuantityName of nds (or sec)TemperatureKelvinKAmount of substanceMoleMolElectric currentAmpereALuminous intensityCandelacd(1) Prefixes: See Table 1.5 for the complete list.

All other acids are weak acids (especially rememberCH3COOH, acetic acid and HF, hydrofluoric acid as weak acids). You should immediately be able to distinguish an acid asweak or strong.8

ADDENDUMS: Requirements for the course and things to think about!!SHOW YOUR WORKWhat does SHOW YOUR WORK even mean? You see it everywhere. It means different things todifferent people. But when in Chemistry, SHOW YOUR WORK means something very specific.When showing work, you’re describing a narrative, giving a step by step recipe for solving aproblem. Even if you know how to solve the problem in your head, SHOW YOUR WORK meansthat you need to know how to express that know-how onto paper. It’s a way of explaining yourthought processes- even the ones you don’t realize that you have. It is a systematic way ofdescribing your work. And on top of that, if a person grading your work does not understandwhat it is, you’re trying to do, they will give up and you won’t get to take part in any of thatsweet partial credit everyone always talks about. Often, poorly shown work will even result in aloss of credit, all because SHOW YOUR WORK is a very specific statement.I’ll use an example, and you may not understand the problem, but the step by step process ishow to solve it.How many moles of Sodium are in a 120.0g sample of Sodium?Step 1: Identify Variables and ConstantsTo perform this calculation, write out what you’re given and identify what dimension the valuemeasures. Include units and give the number as written (to keep significant figures).Mass 120.0 gAlso, other information is provided. Though you will learn about it this year, with the periodictable, knowing that the substance is sodium will give you that the Molar Mass of Sodium is22.99 g/mol. Even though this isn’t a variable, it is a constant (or tabulated value) so youshould list it as well:Mass 120.0 gMolar Mass 23.0 g/mol (we always round our molar masses to one decimal)Last, identify what it is you’re trying to find. You can do this by writing the dimension you’relooking for and signal it’s the missing one with a “?”.Mass 120.0 gMolar Mass 23.0 g/moln (moles) ?So now you’ve listed out your ‘givens,’ you can either use this to identify what equation to use,or you can simply state the equation. Write the equation out that you’re going to use.Mass 120.0 gMolar Mass 23.0 g/moln (moles) ?Molar Mass mass/molesIn this case, we’re using theMolar Mass equation whereMolar Mass equals mass overmoles.

Now, beneath the used equation, rearrange the equation to solve for the unit you’re trying tofind. Do this BEFORE you input your numbers in, so that you can see the properrearrangement of the equation before it becomes a mess:Mass 120.0 gMolar Mass 23.0 g/moln (moles) ?Molar Mass mass/molesMoles mass/molar massThis requires algebra, but it’seasier to do algebra with lettersthan with numbers and units.Once you have the variables declared and the equation solved for the variable you want tofind, plug the numbers in:Mass 120.0 gMolar Mass 23.0 g/mol(moles) ?Molar Mass mass/molesMoles mass/molar mass nMoles 120.0 g23.0 g/molWith the problem clearly described, the numbers clearly entered, it is time to check your workby checking the units. This is a form of dimensional analysis. If your units don’t come outright, then something went wrong.To check this, cross out the units that cancel out in the numerator and denominator. In thiscase, grams cancels with grams and moles is left in the denominator of a denominator(This means it goes to the numerator. Check your algebra books for this if this confuses you.)Mass 120.0 gMolar Mass 23.0 g/mol(moles) ?Molar Mass mass/molesMoles mass/molar mass nMoles 120.0 g23.0 g/molFinally, give your answer to the correct number of significant figures (in this case, 4 based onthe measurement given in the original problem) and the correct unit.Mass 120.0 gMolar Mass 23.0 g/mol(moles) ?Molar Mass mass/molesMoles mass/molar mass nMoles 120.0 g23.0 g/mol Moles 5.217391304347 5.217moles NaOften times, units should include substances. Think logically on these counts. If you say“5.220 moles,” the question is ‘moles of what?’ Say moles of Sodium or “mol Na” to be clear.SHOW YOUR WORK FAQQ: Do I have to show my work all the time?A: When there is math or conversions involved, yes, it is appropriate to show your work.Q: If I don’t, can I lose points?A: Frequently, and this also goes for work that is not coherent and clear. Don’t make a gradersearch for the answer.Q: What if that’s how I solve a problem?A: Unfortunately, SHOW YOUR WORK doesn’t include the following:· Cross multiplying. This is not work, it’s unsolved algebra problems

· Long division or addition/subtraction/multiplication that is written out. Use a calculator forthese.Show me what the operation is neatly and then grab the calculator.· A mess of numbers and lines that Pablo Picasso couldn’t make sense of. Just writing i

packet will be graded. The teacher will personally consult with the parent/student to discuss their future in the class if: 1. the student does not show adequate knowledge of the subject material covered on the pretest. 2. the student does not complete the summer work packet by the first day of class. 3.
