AP Chemistry Summer Assignment 2014-2015Ms Steiner

Woodland High School

To the AP Chemistry Student

Welcome to my AP Chemistry class I am looking forward to helping you gain a deeper appreciation for the science of chemistry and how it impacts our lives I hope you are looking forward to an exciting and challenging year Since you have elected to take this course I assume you have the intelligence and motivation needed to be successful Your hard work will pay off and you will find AP Chemistry to be a very rewarding experience

The Advance Placement Chemistry experience is designed to provide a full year of college-level chemistry so it places heavy demands on the student especially in terms of the time commitment required In fact the College Board suggests that students devote a minimum of five hours per week for individual study outside of the classroom The ultimate objective of course is to prepare you to take the AP Chemistry test in May 2015 and in order to accomplish this topics are covered very quickly For this reason most students take AP Chemistry after they already completed a year of high school chemistry since that provides them with a solid foundation In order to ensure the best start for you next fall I prepared a Summer Assignment that reviews many basic chemistry concepts

It is important that everyone come to the first day of class well prepared Extensive remediation is not an option as we work towards our goal of becoming completely prepared for the AP Exam in early May so seek help early if you are experiencing difficulties

Finally I recommend that you spread out the Summer Assignment rather than trying to complete it in the final week of the summer It takes time for a student to process practice and subsequently learn chemistry at the level necessary for success in AP Chemistry Remember AP Chemistry is an equivalent course to an Introductory Chemistry college course a full year program Taking a college level course in high school is difficult and it requires commitment hard work and time but completion of a class like this is a great investment in your education Prepare yourself and arrive ready to learn

You may want to use the following resources as help for the assignment that follows as well as throughout the year You may also find some of your own

httpwwwcollegeboardcomapstudentschemistryindexhtmlwwwchemmybearcom

The following assignment will be reviewed in class beginning on the first day of school I will take questions on any problems you may have had from this assignment on the first few days of class Therefore you need to have your material with you on the first day Please come prepared

If you have any questions please feel free to call me at 678-201-6813 (if I do not answer please leave your name and a brief message and I will return your call) or email me at dsteinerhenryk12gaus

AP Chemistry Summer Assignment

The following assignment is to be completed and brought on the first day of class

DIRECTIONS Solve the problems below showing your setup calculations units and correct Significant Figures (SigFigs) Neatly-written solutions are acceptable (Points are deducted from AP tests if correct SigFig rules and labels are ignored so get into the habit of using them all of the time)

1 Demonstrate that you know the correct use of significant figures (SigFig digits) by completing the followinga 73890 m has _____ SigFgsb 00304 g has _____ SigFigsc 14 X 104 joules has _____SigFigsd 1 dozen donuts has _____ SigFigsc 40 mL has _____ SigFigsf 800 m has _____ SigFigs

2 A cylinder rod formed from silicon is 213 cm long and has a mass of 500 kg The density of silicon is 233 gcm3 What is the diameter of the cylinder (The volume of cylinder is given by V = πr2h where r is the radius and h is the length)

3 Calculate the following to the correct number of significant figuresa 127 g 5296 cm3 = ________________________

b 12235 g 101 L = __________________________

c 122 g + 038 g = _________________________

d 173 g + 2785 g = _______________________

e 21m x 3215m = _____________________

f 2001mi x 120 min = __________________

g (176 + 2838 + 23 + 11077)g = _________________4 A solid white substance A is heated strongly in the absence of air It decomposes to form a new white substance B and a gas C The gas has exactly the same properties as the product obtained when carbon is burned in an excess of oxygen Based on these observations can we determine whether solids A and B and the gas C are elements or compounds Explain your conclusions for each substance
