Unit Test

We recently took the unit test and it was not the hardest of the year. I am feeling pretty confident on it so I hope I did good on it. it was over electronic structure and periodic trends and was fairly easy to understand compared to other chapters. I hope I am as confident about future tests as I am with this one.

Review for test

This unit has not been difficult, but if not prepared this test can be very difficult just like all other tests. Our test is tomorrow so it would be a great idea to study up. Here are some links to help with the test.

Weekly Quiz

This quiz wasn't that hard. I thought it was easy and I hope that there are more quizzes and tests like this. I studied hard the previous night so that helped a lot. I am going to make sure I study and prepare for future tests and quizzes like how I did for this quiz.

Electronic structure and wavelengths Review

So far this chapter isn't too hard. We learned about the different types of ways to map out an electron in the periodic table. Also we learned about wavelengths. we had to know the formulas for wavelengths and energy. The calculation parts are not to hard. After memorizing and doing some problems I knew it wouldn't be too hard.

Spectroscopic Analysis

In this lab we had to analyze a cobalt and a chromium compound in order to find their absorbance of light using the machine. It was a fairly easy lab to understand and do. However, the machine was very annoying since the knobs were very touchy and it was difficult to get the calibration we wanted. Other than that it was a straight forward lab.

Flame Test

In this lab, we were burning different chemicals with a Bunsen burner to see what colors were produced. The colors created were pretty cool to look at. Some colors would have to be seen through a cobalt glass since it would cancel out the colors we saw.
