The Scott Peterson Case. This case was about a couple, Laci and Scott Peterson who everyone thought they had a good life together, good jobs, nice cars, a golden retriever, a new house, and even a new baby on the way. Scott Peterson began to become unhappy and did not want that new baby with all the stress going on, and instead of getting a divorce he decided to kill his own wife and unborn son! On December 24, 2002, Laci Peterson was reported missing by her husband Scott, she was eight months pregnant. Scott acted very calm and collected about his missing wife, he was on a â€Å"fishing trip† at Berkeley Marina and he when he returned home he seen that lacy was not at home and that was gone from early in the morning to the mid afternoon. They called the cops, and the search for Laci began. It was a huge search over 1,000 volunteers signed up to give information about Laci and her disappearance. There was a 25,000 dollar reward that increased up to 250,000 dollars and then was then increased all the way up to 500,000 dollar reward for any leads that would bring her home. There were posters, and fliers and even a website trying to spread the word about Laci’s disappearance and trying to bring her home to her family and friends. But, There were no signs of Laci anywhere, they began to not believe that she would show up safe anytime soon about halfway thru, but th ey kept looking all the way until March 5th, 2003, when it went from a disappearance case, to a homicide case where Scott Peterson is the biggest suspect they have. Then everyone hopes of Laci coming home safe went down the drain on April 13, 2003. there was a couple that was walking their dog along San Francisco Bay shore in Richmond's Point Isabel Regional Shoreline park, th... ...ut right because i don’t think that any other sentence would be okay. This outcome was correct because he doesn’t get to walk as a free man or even live his life how he was and he doesn’t have the chance to hurt anyone else. If you hurt your child and your wife, who that is supposed to be who you love and protect the most when you are an older man. When you choose to hurt them, your own family i believe you will hurt anyone then. I think that the defendant did receive a fair trial because there were more than 6 jurors, there were about 9, because of the ones who got kicked off, due to different reasons. I think that it was many different point of views. I believe that he received no special treatment, there was so many points and evidence against him, including the lies, and everything he lied about. I think that there was no special treatment to even go his way.

1. (a) I, III, and IV are correct. II is not correct. To explain III, de Broglie's equation states l = h/(mv), so nl = nh/(mv) = 2pi(r). Where: l = wavelength, v = velocity of electron, n = some positive integer, r = distance of electron from center, m = mass of electron. Solve, get mvr = L = nh/2pi. (b) The current wave mechanical model for the atom states that there are an integer number of wavelengths in every standing  integer number (n). 2. (a) The first shell electrons in Lithium are the closest electrons to the nucleus. In addition, there are proportionally more protons to electrons.This pulls the electrons even closer to the nucleus. And in Potassium, the outer shell electrons are a substantial distance from the nucleus. There are a greater number of protons than electrons; however, the large number of electrons dissipates the effect. This is in addition to Lithium being a much smaller neutral atom than Potassium because of the difference in the outer shells. (b) The outer shell for Cl is the same as Cl-; however, Cl-  has more electrons being  attracted by the same number of protons. This weakens the attraction per electron. Since the attraction is weaker, the electrons are farther from the nucleus.Since the attraction is stronger for Cl, the electrons are closer to the nucleus. (c) Although the normal trend is for the ionization energy to increase going to the right in a period, aluminum has a lowered ionization energy and magnesium has a raised ionization energy due to the electron configurations of these two ionizations. This reverses the order of ionization energies. (d) The ionization energy increases each time an electron is removed because there are fewer electrons attracted by the same number of protons while magnesium starts off at a relatively  high value because it begins in one of the preferred forms.The second ionization energy is lowered because losing an electron forms a preferred form and because of this, this is a smaller than normal increase in ionization energy between the first and second ionization energies. The third ionization energy is increased the most because it starts in the most standard form. When you combine this with a lower than normal second ionization energy, you get a very large increase in ionization energy. 3. (a) As you go to the right of the period, there are more protons in the nucleus.The greater attraction makes it more difficult to remove electrons and first ionization energy is the energy necessary to remove an electron from a neutral atom. (b) Although the general trend is to have Boron with a higher first ionization energy than Berylium, Boron's ionization potential is lowered and Berylium's ionization potential is raised, the order is reversed. (c) O loses one electron and makes it easier to remove the electron and lowers the ionization potential. For nitrogen, it more difficult to remove the electron and raises the ionization potential.And since Oxygen's ionization potentia l is lowered and Nitrogen's ionization potential is raised, the order is reversed. (d) Na has a lower first ionization energy than Li and also a lower ionization energy than Ne. Ne has the second highest first ionization energy of all the elements. â€Å"1s2†Ã‚  is the most preferred electron configuration. â€Å"s2  p6†Ã‚  of other shells are also highly preferred. Ne has the second highest first ionization potential because it’s â€Å"2s22p6†. 4. (a) The type of decay expected for Carbon-11 would be positron emission. 116C -; 115B + 01e (b) The type of decay expected for Carbon-14 would be Beta Decay as well. 46C -; 147N + 0-1? (c) Gamma rays have no mass or charge, so they need not be shown in nuclear equations. (d) Measure the amount of Carbon-14 in the dead wood and compare with the amount of Carbon-14 in a similar living object. 5. (a) 23494Pu -; 23092U + 42? (b) The missing mass has been converted into energy (E  =  mc2). (c) A line should be drawn curving downward from the path of the dotted line. This will represent the path of the alpha particles which are repelled by the positive plate and attracted by the negative one. A second line should be drawn upward from the path of the dotted line.This will represent the path of the beta particles which are repelled by the negative plate and attracted by the positive one. The line should curve more than the one for the alpha particles. A third line should be drawn as a continuation of the dotted line. This will represent the gamma rays. (d) Incineration is a chemical process. The only thing any chemical process can do is connect radioactive atoms to other atoms, which has no effect on the radioactivity. 6. (a) As you go down the column in the alkali metals, the outer shell electrons are farther from the nucleus.The attraction for the outer shell electrons is decreased and because the attraction is decreased, therefore the melting point decreases. (b) Intermolecular forces de termine boiling and melting points. Halogens are all diatomic, which means they bond with themselves. In these diatomic compounds, the only intermolecular force is  London forces. The larger molecules can form temporary dipoles easier than small molecules. The larger molecules as you go down the column have a greater attractive force. This increases the melting point as you go down the column. 7. a) As radius increases the heat of reaction decreases. Which means less energy released by ionic attraction. (b) As ionization energy increases the heat of reaction decreases, which means more energy is required to form M2+ while other factors remain unchanged 8. Metals are good conductors of heat, generally malleable, and react by losing electrons to form cations. They tend to have â€Å"s1†,   â€Å"s2†,   â€Å"s2p1†, or   â€Å"s2p2†Ã‚  as their outer shell. Most metals have just â€Å"s1†Ã‚  or  Ã¢â‚¬Å"s2†. Nonmetals are poor conductor s of heat, brittle, and gain electrons when reacting with metals to form anions.Nonmetals have either 3, 4, 5, or 6 electrons in the p subshell in addition to s2  of the same shell number. When the last subshell is a d, the outer shell is s2  of the next shell. Occasionally there will be only 1 electron in the s subshell and this explains when the transition elements are metals. When the last subshell is a â€Å"f†, the outer shell is s2  of the second higher shell and this explains when the lanthanides and actinides are metals. This proves how more than half of the periodic table are metals. 9. (a) â€Å"you have not learned this one yet† (b) â€Å"F2†Ã‚  has the highest  electronegativity  and  electron affinity.Thus it has the greatest attraction for extra electrons. F2   +   2e -;  2F  Ã¢â‚¬â€œ 1   This makes the reaction more likely to occur. â€Å"I2†Ã‚  has the lowest electronegativity and electron affinity. Thus it has less a ttraction for extra electrons making the reaction  Ã‚   I2   +   2e -;   2I  Ã¢â‚¬â€œ 1   less likely to occur. Because it can disperse the charge better, the reaction does occur. (c) The trend for alkali metals shows a very small variation in reducing strength without a real trend. Cesium has the lowest ionization potential and Lithium has the highest ionization potential. However, there is not a great difference in the alkali metals.

A Quick Tour of the First McDonalds

Founder Ray Kroc’s first McDonald’s, known as Store #1, opened on April 15, 1955, in Des Plaines, Illinois. This first store sported a red-and-white tile building and the now very recognizable large Golden Arches. The first McDonald’s offered lots of parking (no inside service) and featured a simple menu of hamburgers, fries, shakes, and drinks. Origins of the Idea   Ray Kroc, the owner of Prince Castle Sales, had been selling Multimixers, machines that allowed restaurants to mix five milkshakes at one time, since 1938. In 1954, 52-year-old Kroc was surprised to learn of a small restaurant in San Bernadino, California that not only had five Multimixers but used them nearly non-stop. Before long, Kroc was on his way to visit. The restaurant that was using the five Multimixers was McDonald’s, owned and operated by brothers Dick and Mac McDonald. The McDonald brothers had originally opened a restaurant called McDonald’s Bar-B-Q in 1940 but revamped their business in 1948 to focus on a more limited menu. McDonalds sold only nine items, which included hamburgers, chips, slices of pie, milkshakes, and drinks. Kroc loved the McDonald’s concept of a limited menu with fast service and convinced the McDonald brothers to broaden their business with nation-wide franchises. Kroc opened his first McDonald’s the following year, on April 15, 1955, in Des Plaines, Illinois. What Did the First McDonald’s Look Like? The very first of Ray Kroc’s McDonald’s was designed by architect Stanley Meston. Located at 400 Lee Street in Des Plaines, Illinois, this first McDonald’s had a red-and-white tile exterior and large Golden Arches that flanked the sides of the building. Outside, a large red and white sign announced the â€Å"Speedee service system.† Ray Kroc wanted quality with quick service and so the first McDonald’s character was Speedee, a cute little guy with a hamburger for a head. Speedee stood on top of that first sign, holding another sign advertising â€Å"15 cents† – the low cost of a hamburger. (Ronald McDonald would replace Speedee in the 1960s.) Also outside were plenty  of parking spots for customers to wait for their car-hop service (there was no inside seating). While waiting in their cars, customers could order from the very limited menu that included hamburgers for 15 cents, cheeseburgers for 19 cents, French fries for 10 cents, shakes for 20 cents, and all other drinks for just 10 cents. Inside the first McDonald’s a crew of workers, wearing dark slacks and a white shirt covered by an apron would prepare the food quickly. At the time, fries were made fresh from potatoes and Coca Cola and root beer were drawn directly from a barrel. The McDonalds Museum The original McDonald’s underwent a number of remodels over the years but in 1984 it was torn down. In its place, a nearly exact replica (they even used the original blueprints) was built in 1985 and turned into a museum. The museum is simple, perhaps too simple. It looks just like the original McDonald’s, even sporting mannequins pretending to work at their stations. However, if you want to actually eat McDonald’s food, you have to go across the street where a modern McDonald’s awaits your order. However, you may have more fun by visiting these eight amazing McDonalds restaurants.
