Given: At the peak of the Antarctic ozone hole, about one-half ofthe initial ozone concentration at 16 km of 5 x 10^18 m^-3 is lostin 30 days. The rate-limiting step in the catalytic ozonedestruction cycle is thought to be ClO dimer formation.

ClO + Clo + M --k--> ClOOCl + M k = 8 x 10^-44 m^6 s^-1

Q: Determine an expression for the ozone loss rate.

Would it be the derivative of the ozone exponential decay of [O3] =[O3o] * e^ (-kt) which is dO3 / dt = -k * O3o * e^ (-kt)?

The rate constants for the reactions of atomic chlorine and hydroxyl radical with ozone are given by 3 x 10-11e-250/T and 2 x 10-12 e-940/T where T is the temperature in Kelvin. Calculate the ratio of rate of ozone destruction by atomic chlorine to the rate of ozone destruction by hydroxyl radical in the Antarctic ozone hole, in which the temperature is -80 oC and the concentrations of atomic chlorine and hydroxyl radical are equal. Assume that the reaction of ozone with the X. species ( either atomic chlorine and hydroxyl radical) is rate determining.

NARRATIVE OF THE

CHAPTER VII.

I LIVED in Master Hugh's family about seven years. During this time, I succeeded in learning to read and write. In accomplishing this, I was compelled to resort to various stratagems. I had no regular teacher. My mistress, who had kindly commenced to instruct me, had, in compliance with the advice and direction of her husband, not only ceased to instruct, but had set her face against my being instructed by any one else.

It is due, however, to my mistress to say of her, that she did not adopt this course of treatment immediately. She at first lacked the depravity indispensable to shutting me up in mental darkness. It was at least necessary for her to have some training in the exercise of irresponsible power, to make her equal to the task of treating me as though I were a brute.

My mistress was, as I have said, a kind and tender-hearted woman; and in the simplicity of her soul she commenced, when I first went to live with her, to treat me as she supposed one human being ought to treat another. In entering upon the duties of a slaveholder, she did not seem to perceive that I sustained to her the relation of a mere chattel, and that for her to treat me as a human being was not only wrong, but dangerously so. Slavery proved as injurious to her as it did to me. When I went there, she was a pious, warm, and tender-hearted woman. There was no sorrow or suffering for which she had not a tear. She had bread for the hungry, clothes for the naked, and comfort for every mourner that came within her reach. Slavery soon proved its ability to divest her of these heavenly qualities. Under its influence, the tender heart became stone, and the lamblike disposition gave way to one of tiger-like fierceness. The first step in her downward course was in her ceasing to instruct me.

3. How does Mrs. Auld change once she is exposed to the evil power of slavery? (Chapter VII)

4. How does Douglass describe Mrs. Auld's transformation due to the influence of becoming a slaveholder?

What effect does the number of lines in stanza 8 have on the poem?

FeO (s) + Fe (s) + O2 (g) → Fe2O3 (s)
Given the following table of thermodynamic data,

Substance ΔHf(kJ/mol) S(J/mol-k)

FeO(s) -271.9 60.75

Fe(s) 0 27.15

O₂(g) 0 205

Fe₂O₃(s) -822.16 89.96

A Diamante Poem follows a very specific format - there are seven lines, and each line must have a specific number and type of words. When you're finished, the poem will be in the shape of a diamond! Look at the format and example below, and then try writing your own diamante poem.

Line 1= Topic (noun)

Line 2 = Two describing words (adjectives)

Line 3 = Three action words (-ing verbs)

Line 4 = Four words: Two words about the topic and two words that are opposite of those in line 2

Line 5 = Three action words for the ending noun (-ing verbs)

Line 6 = Two words to describe ending noun (adjectives)

Line 7 = Ending noun (opposite of Line 1)

Directions: Create four diamante poems of your own.

Directions: Write poems using the following structure:

1. Choose a word that means something.

2. Write three words that end with "ing" telling what your word does.

3. Write a short sentence that tells about your word.

4. Choose a word that describes your word.

5. Write seven (7) poems in this format; one for each day of the week!

Here is an example for you to follow:

5. Could genocide, or the mass extermination of people, happen today? Why or why not?

1. Research and explain the difference between Budgets, Credit Cards, Payday Loans, and Debit Cards.

3. Write a contract with yourself outlining how you will avoid consumer fraud. Be specific in your plan.
