Sorry the assignment isn’t posted yet. I’m sure you’re heartbroken. I’ve been going through videos trying to find some that cover the material in an appropriate way. I figured with all the chemistry and biology videos it would be easy. Yeah…not so much. In one particularly memorable video it sounded like the person was eating as they recorded it. Anyway, after several hours of video viewing I have yet to find some that meet my goals. So, apparently I’m going to have to make my own. So, I’m going to try and turn out one chem and one bio video a day this week (wish me luck with that, or not). I’ll post them as soon as I get them done. They will still be short (8-15 min) and there will still be a short exercise following each. So until I’ve got some posted try and make the best of your spring break, I know it will be difficult. You’re probably suffering the effects of science withdrawal already.

The following link (Chem_Unit05_Lab_RxStoi)is to a pdf of the Stoichiometry lab you will do on Thursday. You can use it to prepare your lab notebook for the lab. The following table contains the reactants you will be using, the product that will be produced and the quantity of product to produce.
