Unit2 Exam Review

Review for Exam

Exam Next Week - Wednesday December 18th

Concepts in Unit 2 that will assessed on the exam:

Ionic vs. Covalent Bonding

Orbitals

Bohr and Quantum Mechanical Model of the Atom

EM Radiation

Lewis Structures

Electron Configuration

Design/Use of Periodic Table

Periodic Trends

periodic trends practice

Here are some practice problems and animations associated with periodic trends.  The last 2 documents contains material that we have covered and also some material that we will be covering soon.

Lewis Structure Generator - Practice

Check out the links below.  They give you some Lewis Structure practice.  Some of the molecules are beyond the scope of this class, so skip the ones that are too confusing.

ans key for exam prep

here are all of the keys in one file.....

Exam Prep

Here are some new practice problems to aid in your exam prep (NOTE:  Not every question relates to what we have covered.  We are at a different point in the material compared to last year, so there are some questions that reference material we have yet to cover.  Ignore them please.

Practice 1 (old quiz)

Practice 2 (old quiz) - this reference using the "back of the sheet" - there was a periodic table copied with it.  Use your own periodic table when needed.

Practice 3 (last year's exam)

Practice 4 (EM Radiation)

Practice 5 (Exam from 2010)


ANSWER KEYS SOON TO FOLLOW

Naming Ionic Compounds and Covalent Molecules

Here is an online quiz generator for naming.  You may not be REQUIRED to know the same ions quizzed here, but most should be familiar.  If need be, look up what you are not supposed to know and use it properly.  You can continue to click TRY AGAIN to get new questions.

Also,  I have posted two Naming Tutorials under class resources.  They walk you through the steps taken to correctly name chemicals.

Update to Class Resources Page

The Class Resources page has been updated to include presentations for Unit 2.  Please add them to your studying before/after class, in addition to the suggested readings.

Essential Element Name List

Please begin the learn the "Essential Elements" List
It will be archived in Important Documents

Extra Isotope Practice

Here is another Isotope Grid to practice.  Answer key will be posted later.

Isotope 2

Calorimetry - Specific Heat Virtual Lab

Specific Heat of Unknown Metal Applet

Consider the applet as you study the basics of calorimetry, heat transfers and specific heat.

Density Practice Problems

Density Practice Problems

Range of problems from easy to hard....30 problems and answers with explanations.

EXAM REMINDER

Reminder that you will have a Unit 1 Exam during our next day 3 class (8:30 am block).  This will occur on Tuesday October 1st.

Course Readings can be found under the Important Document tab

Metric system conversions handout is also under Important Documents

There are a handful of presentations under the Study Resources tab

There are also example problems under the Study Resources tab

Good luck and let me know if you need to meet for any extra help.

Marx

Significant Figures Practice

Check the resources page for SigFig practice problems.

Cheeto Lab and Sci-Notation Practice

Reminder that you are required to bring in something that can:

Hold a cheeto that is on fire

Hold water above the cheeto that is on fire

Insulate the apparatus to ensure all heat from said cheeto goes into the water.


For those of you looking for Scientific Notation Practice, look under the class resources tab above

FIRST QUIZ

Your first quiz will encompass the concepts and content we have looked at to date, including lab.  I am estimating the quiz should take between 20 and 30 minutes.  More details will follow as we continue with Unit 1 this week.

Expect the quiz to include:  Questions involving laboratory techniques, equipment, safety and measurements, unit conversions using the factor label method (dimensional analysis) and density.

Unit 1 Quiz - Day 5 - Tuesday September 17th.

Unit Conversion Practice Problems

Check out the following links for Conversion Problems similar to the ones we did in class and VERY similar to those you will be quizzed/tested on.

Note:  The bottom link contains 3 separate links to sample problems with answers.

In total, there are 46 practice problems that you may do.....if needed.


Also, here is a tutorial that walks you through the steps we took in class.  If you did not take the best notes or needed a brush-up, check it out

Study Resources Update

I have begun to add some more documents to the pages above.  There are a few presentations to supplement your notes and the readings under Class Resources.  Also, I have added a document that lists the Metric System prefixes and has some helpful English to Metric conversions.

Equipment Use Update for Missing Videos

So....

The links on the Equipment ID and Use lab are not working - I love technology - so here are two to watch.

Using a scale

Handling Liquids

Welcome you lucky sophomores

Welcome to Mr. Marx's General Chemistry Blog.  I will use this as an important form of communication for my general chemistry class.  Assignments will be posted along with other resources including online texts, animations, simulations, presentations, etc.

Check back often...
