GeneralWhat mood is created by the following excerpt from Agee's "Knoxville: Summer of 1915"?
"These sweet pale streamings in the light out their pallors and their voices all together, mothers hushing their children, the hushing
unnaturally prolonged, the men gentle and silent and each snail-like withdrawn into the quietude of what he singly is doing, the urination of
huge children stood loosely military against an invisible wall, and gentle happy and peaceful, tasting the mean goodness of their living like
the last of their suppers in their mouths; while the locusts carry on this noise of hoses on their much higher and sharper key"

GeneralThe standard enthalpies of formation, at 25.00 °C, of methane (CH4(g)), water (H₂O(1)),
and carbon dioxide (CO2(g)) are, respectively, -74.6 kJ/mol, -285.8 kJ/mol, and -393.5
kJ/mol. Calculate the amount of heat released (in kJ) during the combustion of 15.86 L of
methane under a constant pressure of 1.000 atm at 25.00 °C (N.B. combustion is the
reaction with molecular oxygen to produce water and carbon dioxide.)

GeneralRead the following excerpt from N. Scott Momaday's House Made of Dawn. Which of the following literary devices is most prominent in the excerpt?
"They were golden eagles, a male and a female, in their mating flight. They were cavorting, spinning and spiralling on the cold, clear columns of air, and they were beautiful. They swooped and hovered, leaning on the air, and swung close together, feinting and screaming with delight. The female was full-grown, and the span of her broad wings was greater than any man's height. There was a fine flourish to her motion: she was deceptively, incredibly fast, and her pivots and wheels were wide and full-blown. But her great weight was streamlined, perfectly controlled. She carried a rattlesnake; it hung shining from her feet, limp and curving out in the trail of her flight. Suddenly her wings and rail fanned, catching full on the wind, and for an instant she was still, widespread and spectral in the blue, while her mate flared past and away, turning round in the distance to look for her."

GeneralNitrogen forms a surprising number of compounds with oxygen. A number of these, often given the collective symbol NOx (for "nitrogen + x oxygens") are
serious contributors to air pollution. They can often be interconverted, sometimes by reaction with oxygen or ozone (03) in the air.
An atmospheric scientist decides to study the reaction between nitrogen trioxide and oxygen that produces nitrogen dioxide and ozone. She fills a stainless steel
reaction chamber with 1.1 atm of nitrogen trioxide gas and 9.1 atm of oxygen gas and raises the temperature considerably. At equilibrium she measures the
mole fraction of nitrogen dioxide to be 0.072.
Calculate the pressure equilibrium constant K, for the equilibrium between nitrogen trioxide, oxygen, nitrogen dioxide and ozone at the final temperature of the
mixture.

General3. When adding or dividing measured numbers, we don't count significant figures. Instead, we look at the precision of the measured numbers. The answer can only be as precise as the least precise measurement.
For example: 10.1 +93.4 = 103.5, because both 10.1 and 93.4 are precise to the tenths place. Solve the following problems assuming all the numbers are measured. Report the correct number of
significant figures.
a. 87.3 +0.001 =
b. 0.201 +0.92 =
c. 320 +8.41 =
d. 1200-60=
