HS Chemistry - Dec. 2018

Here is the most recent tentative schedule. Note: Test and Quiz Dates, on upcoming Fridays.

As usual, Labs will be on Thursdays.

[amityschool-science-cheung-blog]

Chemistry - HW #9

1)  Choose any 3 new (different from the ones your chose last time) Problems at the end of the Class-notes/Slides.   You may choose the Regents Questions, if you wish. Copy the question, Answer the question, and Write out an explanation for your answer, using at least 2 complete sentences for each one. ---------------------------------------------------------------------- 2) Read pages 90 to 98 of HOLT Chemistry. Copy the Questions and Answer, neatly Section Review # 1, 2, 3, and 9 on page 89. Copy the Questions and Answer, neatly Interpreting Graphs # 10 page 113. ---------------------------------------------------------------------- EXTRA HINT for #10:  s levels hold 2 electrons, p levels can hold 6 electrons, d levels can hold 10 electrons, and f levels can hold 14 electrons.

You know that the first orbital (n=1) can only hold 2 ( s, only ) electrons, the second orbital (n=2) can hold 8 ( s + p ) electrons, and the third orbital (n=3) can hold 18 ( s + p + d ) electrons.   Even though you don’t have to memorize the different levels specifically, you can figure out which one contains the very last electron, since you are filling in each level with 1 electron at a time --- knowing a S can hold 2 max, a P level can hold 6 max, and a D level can hold 10 max.

This is due Tuesday, 12 / 4 / 2018.
