CHEMISTRY: Happy snow week! Here’s the lesson for Wednesday. It’s the LAST of the notes from chapter 8. At the end is a great review of completing and balancing equations. Also be sure and check the syllabus to find out about the optional homework assignment that will be great help if you’re having trouble predicting products of reactions.
So guess what happens when a gummy bear falls into a test tube of molten potassium chlorate?! Click on the video below to find out! Do you reckon that it’s a physical change or a chemical change? Why do you think?
Remember these steps when you are completing chemical equations: #1 – write the correct formulas; #2 – ask yourself what type of rxn it is; #3 – find the rule that applies and go for it! Don’t forget also that if you answer single replacement to #2 (or the synthesis or decomposition of a metal oxide!) you’d better check the activity series first!! Good luck!
