Qualitative Analysis and Final Exam Unit 9

For the last few weeks of school we will be working on qualitative analysis of unknown solutions.  This extended lab will summarize many of the reaction types we have studied this year and will increase student analytical skills.

The final exam will be comprehensive.  Students should review all notes from the year, study chapter reviews and complete a practice exam during the last days before the final exam.

Stoichiometry Unit 5

This unit is on stoichiometry.  You will be studying chemical formulas, reactions, equations and the mole concept. There will also be some work done learning mass and gaseous volume relationships; the ideal gas equation. Chapter 8 complete questions 1 to 35 odd.  Chapter 9 complete questions 1 to 29 odd.  There are many online videos that can help you learn stoichiometry.  Outside of what we learn in class, I suggest using khan academy or brightstorm to 'pick it up the first time' and reviewing with the IB style thornley videos or crashcourse... see links below.  Continue to work on memorizing ions from the previous unit if you have not learned them all yet. You will use them throughout the rest of the year. Keep memorizing ions!  Test on 2/26

 In addition to study of the text and your class notes you should consider the internet, especially YouTube chemistry channels, an essential part of learning chemistry well.  WATCH THE VIDEOS... you will slowly build important concepts...

Students who are not prepared in math skills are the students who struggle the most and have to spend the most time on chemistry.  If you are not concurrently enrolled in algebra 3-4 or above you may not really have the prerequisite math ability for chemistry.  Students in geometry will need to spend more time on problem solving parts of chemistry, especially in the second semester, to keep up.

Intro Quantitative Chemistry Unit 1

WELCOME TO CLEVELAND CHEMISTRY...

 This is the introduction unit for Chemistry year 1.  In Modern Chemistry you should read and study chapter 1 and complete the odd questions 1 to 23 at the end of the chapter.  There will be a quiz on 9/18 and the questions are due by the class day before this.  You should also read and study chapter 2 and complete odd questions 1 to 45 at the end of the chapter.  There will be a test on 9/25 on this unit and all work in the unit is due by this day at the latest.  No work will be accepted for this unit after 9/25.

You need to know HOW TO STUDY CHEMISTRY.  This course can quickly become difficult if you do not have study skills and do not PRACTICE study skills.  Read page 904 to 907 in the text book on study skills, it has some really useful advice.  The most useful is to read and problem solve ahead of class.  

Students who are not prepared in math skills are the students who struggle the most and have to spend the most time on chemistry.  If you are not concurrently enrolled in algebra 3-4 or above you may not really have the prerequisite math ability for chemistry.  Students in geometry will need to spend more time on parts of chemistry, especially in the second semester to keep up.

Please read the syllabus and put the important websites from this link into your notes.  In addition to study of the text and your class notes you should consider the internet, especially YouTube chemistry channels, an essential part of learning chemistry well.  WATCH THE VIDEOS... you will slowly build important concepts...
