Hon Chemistry 11-30-18 Properties of Radioactive Isotopes

HON CHEMISTRY: Can you guess what it is?/ It’s a picture of uranium ore under UV light. Cool, huh! Here’s the discussion from Friday on the average atomic mass homework problems and then the rest of our discussion of the properties of radioactive nuclides.

Chemistry 11-30-18 Empirical Formulas

CHEMISTRY: So, would you like to be Greg on CSI? Great start on empirical formulas today!

The hardest part is that it’s not a set formula for you to plug and play, but if you’ll keep in mind that you’re really just looking for subscripts which are just moles, you’ll be able to think it through. Percent to mass, mass to moles, moles to smallest whole number ratio.

Monday we’ll talk about a little step you get to add at the end. 🙂
