PHYSICS: Great job today on making connections between work and energy! I think you’ll like using the work-energy theorem, it’ll save you some time and a couple of steps. Don’t forget about friction!

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. Tomorrow we’ll talk about a little step you might have to add at the end. Also tomorrow, quiz?!?
