Wednesday, Day 4
Honors: we highlighted the differences between nuclear fission and nuclear fusion; note that, though these are opposite processes, both processes involve the conversion of some nuclear mass to energy, which is why both processes are highly exothermic/energy-releasing. Tomorrow, we have our nuclear physics unit test.
Friday, we will do our colligative properties/ice cream lab. Make sure that you bring gloves and your winter-wear to class. Bring rain-gear in case of inclement weather.
Regents: we did a few more molarity problems involving mass of solute and volume of solution. We then discussed how to dilute a solution to a particular molarity by adding a certain amount of solvent. We derived the "solution dilution" formula, which has the mnemonic "voom- voom"; then, we applied the formula to a couple of solution dilution problems.
Reinforce this information by doing the assigned homework in chapter 16 of the text.
Friday, we will do our colligative properties/ice cream lab. Make sure that you bring any "blend-ins" that you want in your ice cream; also bring gloves and your winter-wear to class. Bring rain-gear in case of inclement weather.
AP: we finished our polyprotic acid problems. We then started on the more qualitative part of the unit by explaining the relative strengths of a series of acids by weighing their relative bond polarities and bond strengths.
