Fill in the following blanks.
As the dye concentration increases, the absorbance of the light [linearly increases, linearly decreases, exponentially increases or exponentially decreases].
The dye concentration units are [molar (M), millimolar (mM) or grams per liter (g/L)] .
Although most people wrongly conclude that absorbance has units nm, in fact, absorbance is unitless. This is because it results from a ratio of light through a colored sample relative to light intensity through a clear (blank) sample.
The units for the slope of the graph would be [mM, 1/mM or nm] . Hint: the slope is the change in y values divided by the change in x values.
The units for the y-intercept of the graph would be [nm, nM or unitless] .
The value for the slope of the line that describes the absorbance data is [6.4597 or 0.0008]
The value for the y-intercept of the line that describes the absorbance data is [6.4597 or 0.0008] .

Bucks McGee, after being poisoned, is currently being treated in the hospital with an
antidote- the chemical Fe-(CN)18. The compound is so intensely coloured that even a small
amount of it makes for a black or dark blue suspension.
Given that this antidote has never before been administered at the hospital, none of the
doctors or nurses have experience with it. There is one very old bottle of Fe-(CN)18 pills in
the medicine store-room, but the label is worn and the units are in the old, archaic British
Apothecaries' system which has unusual units like drachms, scruples, grains, and mites:
453.6 grams (g)
= 1 pound (Ib)
= 12 ounces (3)
= 96 drachms (3)
= 288 scruples (3)
= 5760 grains (gr)
= 115200 mites (m)

Uranium-238 (U238) has three more neutrons than uranium-235 (U235). Compared to the speed of sound in a bar of U235, is the speed of sound in a bar of U238 higher, lower, or the same? There are several
factors that play a role.
(a) Chemically, the atoms of these two isotopes behave in essentially identical ways, since the number of protons (92) is identical and the clouds of 92 electrons are nearly identical. The interatomic distance, and
the effective "stiffness" of the interatomic bond, both depend on the chemical properties of the atoms. Therefore, which of the following statements are true?
O The effective stiffness of the interatomic "spring" is greater for U238 because the mass is greater.
O The effective stiffness of the interatomic "spring" is the same in the two isotopes, since this "spring" is a model for the interactions of the outer electrons, which are the same for different isotopes of the
same atom.
O An atom with more mass in the nucleus is bigger, so the distance…

The life cycle of a plastic bottle
After reading the text below, answer the following questions. Make sure to put it in your own words.
This is the story of three plastic bottles, empty and discarded. Their journeys are about to diverge with outcomes that impact nothing less than the fate of the planet. But they weren't always this way. To understand where these bottles end up, we must first explore their origins. The heroes of our story were conceived in this oil refinery. The plastic in their bodies was formed by chemically bonding oil and gas molecules together to make monomers. In turn, these monomers were bonded into long polymer chains to make plastic in the form of millions of pellets. Those were melted at manufacturing plants and reformed in molds to create the resilient material that makes up the triplets' bodies. Machines filled the bottles with sweet bubbly liquid and they were then wrapped, shipped, bought, opened, consumed and unceremoniously discarded. And now here they…

Introduction
Home Depot's market research shows that they can sell 20-lb. bags of ammonium
phosphate, a common fertilizer with the chemical formula (NH4)3PO4, for $9.99/bag.
This price has been marked up 6% from the wholesale price that they pay to the
manufacturer. You decide to use your knowledge of chemistry to produce your own
ammonium phosphate and sell it to Home Depot at 5¢ below the wholesale price.
You contact a packager, who agrees to package your product for 29¢ per bag.
Ammonium phosphate is produced from ammonia (NH3) and phosphoric acid
(H,PO4). Ammonia, in turn, can be produced at a 50% yield via the Haber process,
using a mixture of hydrogen (H2) and nitrogen (N2) gases with an iron catalyst.
Phosphoric acid is obtained from a naturally occurring mineral called fluorapatite,
Cas(PO4)3F, by the following process: fluoroapatite is mixed with silica sand (SiO2)
and coke (elemental carbon, C) in an electric furnace. The products are carbon
monoxide (CO), tetrafluorosilane…
