Students are to reinforce our class discussion on phase changes by answering question #’s 28, 30, 31, and 32 on page 430.

We will discuss and elaborate upon how matter changes when energy is added or removed and analyze its aspects through a phase diagram for water at different temperatures and pressures.

Students were expected to read Section 12.1 on gases and answer the study guide that was assigned on the subject matter on Monday and due on Wednesday. Regrettably, since many of them failed to simply read and write last night, Tuesday, the assignment has been … Continue reading →

We will briefly review our test on limiting reactant and percent yield, and then elaborate upon how matter behaves in terms of a particle’s size, motion, and energy. We will also distinguish between compression and expansion of a gas in … Continue reading →

Students will be evaluated upon the limiting reactant and percentage yield since in certain situations, one will not be able to determine the percent yield without finding out the limiting reactant that will also play a role in determining the … Continue reading →

Students are to reinforce the percentage yield topic by solving problem #’s: 14 and 15 on p.983! NOTE THAT WE WILL BE HAVING A TEST ON PERCENTAGE YIELD ON TUESDAY, MAY 8TH, 2012.

Students are to practice on determining the percentage yield through the use of the limiting reactant by solving problem #’s: 93, 94, & 96 on p.388.

We will discuss and reinforce the method of determining the percentage yield through the stoichiometric process that we have learned, applied, and put into practice.

Students will be evaluated upon their skills of determining the limiting reactant in a chemical reaction as well as the reactant that is in excess, and the amount of the excess reactant that is leftover after the reaction is complete.

Students are to practice further on determining the limiting reactant, the excess reactant, and the masses of the products that are produced. Therefore, they are to solve question #’s: 12 and 13 on page 983.
