AP Chemistry Summer Assignment



AP Chemistry Summer Assignment To: AP Chemistry Students and their parents From: Mr. Finnegan Re: AP Chemistry Summer Assignment 2020-2021 There are several important reasons for doing AP Chemistry homework over the summer: To review basic concepts of chemistry. To practice math skills which you will need for AP Chemistry. To hit the ground running when we return in the fall. AP chemistry covers a lot of concepts at a fast pace. We need to get started right away and not spend valuable time on introductory concepts. There are essential math skills and basic principles in chemistry you need to be familiar with on day one. Included in this summer assignment are a number of references, tables, formulas, and videos that will help you complete this assignment. Complete both the math and chemistry assignments that are attached. The assignment will be collected and will be a grade. If you have any questions or trouble completing any of the problems, don’t hesitate to email me at finneky@boe.richmond.k12.ga.us. I will be on vacation or at conferences at various times during the summer but I will get back to you as soon as possible. Forming study groups to complete these assignments is encouraged, however it does you no good to copy answers from a classmate or have google answer every questions for you. This assignment may look long, but I promise you it will make the year easier by familiarizing yourself with the content. Have a great vacation, Mr. Finnegan Resources Academy. This has videos and resources that will show you how to do pretty much everything on this assignment. Khan Academy is one of the best online resources for chemistry. is essentially the library of chemistry concepts. You should be able to find articles on here for all the work below. course is a youtube channel with videos about chemistry principles. This is another great resources for reviewing or looking up chemistry concepts. Dynamic Periodic Table has a huge amount of information on elements in the periodic table.AP Chemistry Summer Math Assignment Supply the answers in the blanks. Answers should be written with the correct number of significant figures. You should be able to calculate these answer WITHOUT a calculator. There are sections on the AP exam where you cannot use a calculator, so you need to get accustomed to doing math without one. 1.62 x 106 + 1.9 x 105 = ________________________ 1.62 x 106 - 1.9 x 105 = ________________________ 3.72 x 10-8 + 0.211 x 10-7 = _____________________ 3.72 x 10-8 - 0.211 x 10-7 = _____________________ (2.3 x 104)(3.1 x 104) = _________________________ square root of 9.0 x 10-8 = ______________________ 10x = 2 and log 2 = 0.30; x = ____________________ x= _____________ if x2/0.10 = 4.0 x 10-9 x = ______________ if xy = 16 and y2 =225 log (1.0 x 104) = ______________________ log (1.0 x 10-4) _________________________ log (2.3 x 10-5) = ___________________ x + y = 3 and x – y = 9; x = __________________ (0.001)(0.001) = ______________ 3.42/342 = ______________ If a megabuck is one million dollars and a kilobuck is one thousand dollars, how many kilobucks is 342 dollars?

I know this was a lot of work but it will be worth it when you show up next fall and already have some chemistry skills. This will be a tough class, but I have faith in all of you and I know you will be smarter and wiser at the end of the year. Let’s have a great year! ................
