Friday, Day 2
Honors: we did several percent composition problems: percent of each element in a compound and then percent of water in a hydrated salt (a "hydrate").
We then did the REVERSE process of going from percent composition to EMPIRICAL formula of a compound. Practice these problems from the worksheets over the weekend.
Regents: we finished how to recognize five common reaction types: synthesis, decomposition, single replacement, double replacement, and combustion. We balanced several equations and learned some time-savers and strategies on how to balance some of the tougher problems involving combustion and double replacement.
Practice the equation balancing worksheets this weekend.
AP: we learned about Q, the reaction quotient, and how to compare its value to K in order to predict whether a reaction will shift towards making more products or reactants as it proceeds towards equilibrium.
We then learned the MAIN bookkeeping method that we will employ for the rest of the course: the ICE TABLE!
I will put up the Ti-83 solver tutorial for any quadratics that we need to solve quickly (this will be much faster than getting the equation into proper quadratic form); even better, a graphical solution will be easier to do so I will put up a tutorial on that also.
