## CHEM 1050-Chemistry and the Citizen Podcasts

Since there is some course material overlap between CHEM 1050 and CHEM 1090, some podcasts will work for both courses. If you are viewing a podcast and you see “CHEM 1090" or “General Chemistry I" in the title, don’t panic! I’m using it for both courses.

### Chapter 2-Chemistry and Measurements

Significant Figures: Introduction (10m44s, 1/7/2011)

Dimensional Analysis: Introduction (8m45s, 12/23/2014)

An attempt to convince you of the need to use units in calculations.

Dimensional Analysis: How to Correctly Show Your Work (12m43s, 12/24/2014)

This takes the previous podcast, "Dimensional Analysis: Distance from Speed and Time", and demonstrates a couple of alternate ways you can show your work. I also demonstrate an incorrect way to show your work and explain why it's wrong.

### Chapter 6-Ionic and Molecular Compounds

Some of the spoken comments in these podcasts are for my CHEM 1090 students. For my CHEM 1050 students, I will let you know if the compound is ionic or molecular.
