The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

This was not the only similarity though, rudders were rather mainstream at that point and so both of the different ships used the same method of control. Large wooden rudders planted at the back of the ship would catch the water like a sail beneath the surface of the water creating resistance and shifting the bow in the opposite direction. The rudder is still being used in almost all sailboats, and has evolved very little, even after hundreds of years.

My unknown organism #6 is Morganella morganii, which is a gram-negative bacillus rods commonly found in the environment and also in the intestinal tracts of humans, mammals, and reptiles as a normal flora. (3, 5) This bacterium Morganella morganii, was first discovered in the 1906 by a British bacteriologist named H. de R. Morgan. (2) Despite its wide distribution, it is an uncommon cause of community-acquired infection and is most often encountered inpostoperative and other nosocomial settings. (2, 3) Morganella morganii infections respond well to appropriate antibiotic therapy; however, its

It's the 1800s and industrialization is thriving throughout America. People are moving away from an agricultural way of life, moving into cities, developing arts and trades and trying to expand their boundaries of who, where and how they can trade marketable items. In trying to reach more and more customers at further and further distances the ability to travel further in less time creates a demand. In this time period most of the trade routes revolved around rivers as this was the easiest method of transportation and the mighty Mississippi being the largest trade route.  However, the problem with traveling the Mississippi or any riverway at this time is that you are at the mercy of the wind and currents. At this time you travelled by boat with full sail and could not maneuver against tides or a poor wind.  There was a need to create something that could deal with this dilemma.  More and more inventions and machines are being created. With these inventions it becomes effortless to complete painstaking tasks. The effect of this is tade becoming more

The purpose of this lab was to identify unknown bacteria cultures using various differential tests, and my unknown bacteria is #17. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways, each was used in a way to help recognize those specifics and identify the unknown cultures. The differential tests used to identify the unknown cultures were Gram stain, Catalase, Mannitol Salt Agar (MSA), Blood Agar, Novobiocin, Coagulase, and DNAse (Alachi, 2007).

Bacteria are ubiquitous; they can be found on the skin, in the soil, and inside the body. Because of the very nature of this ubiquity, it is important to be able to determine between different strains of bacteria. An example of this is determining the causative agent for a disease so that the patient will be treated with the appropriate antibiotics. It may be important to determine the bacteria in a certain region, because like with enteric bacteria, it is normal to find them in the digestive tract as they are in a symbiotic relationship with our bodies in this area; however, they also cause opportunistic infections in places outside of the digestive tract to our detriment, such as with a urinary tract infection. Some strains of bacteria are common to nosocomial infections, and identifying these bacteria as such helps create the guidelines for healthcare workers in antiseptic technique. All of the morphology and characteristics of each strain of bacteria help us to better understand the role of bacteria in the body as well as helps us understand how they can cause illness, and what treatment regimen to set in place. In lab this semester, a sample of unknown

required to have the ship sail in zigzag formation which gives the ship a higher chance from

Our boat is in a square shape so that the pennies can equally balance in each corner and the center. As seen on page 14 the material that makes up the boat are popsticle sticks because they seem to be stronger. If they’re stronger they will be able to hold more pennies. The popsticles have a length of 11 cm, we decided to have this size because we couldn’t add another roll of popsticle sticks since we were going to exceed our budget which was $1, 500.00 (page 12). If we include the propeller, the length of the boat would be 19 cm (page 9), due to the paper clip and wooden stick being added between the straw as seen on page 18. Me and my partner chose this deisgn because we wanted to create an innovative propeller, so we used straws, paper clips,

Triple Sugar Iron Agar test, there was a gas production seen in the media. The media was yellow slant and yellow butt indicating glucose, lactose and/or sucrose fermentation with acid accumulation in slant and butt. For sulfur reduction, it was negative since it did not turn black in color indicating no sulfur was reduced.

top of the boat, the triangular sails have to be angled in a slightly more forward direction

2. (5 pts) List and explain the names and affiliations of the various characters/stakeholders in this story – I’m looking for us to use the story to map out the complexities that are generally associated with solving public health puzzles – the stakeholders you list and explain here should apply to many of the cases we consider going forward.

An unknown was given to our group from the professor. The unknown was in nutrient broth, the group received unknown number 3. And the task was to identify the unknown and try to make an educated guess, and identify the unknown #3.

The results in this lab showed that suspect 2 was a match for the DNA found at the crime scene. This was determined by DNA fingerprinting. In this lab, the samples of DNA from two suspects and the DNA from the crime scene were cut with two different restriction enzymes and then the DNA was run through gel electrophoresis. The different restriction enzymes cut the DNA in different places, so when the DNA was run through the gel, the gel showed two fragments for each sample based on their size. The fragments shown are known as bands of DNA. These bands of DNA for each suspect were analyzed and compared with the bands of the DNA from the crime scene. The bands of DNA were compared based on the distance they traveled through the gel from the wells.

Boats come in many different shapes and sizes. Though they can be fun toys, there is a lot that to consider when diving into the physics behind it. There many factors that need to be taken into consideration when building a boat, a few of the important ones are weight, rudders, the position of a rudder and the position in which a motor is placed. Each of these factors are what either make or break a boat.

The boat project was an enjoyable one. This project was able to test many abilities of the average student including teamwork and preparation. It also offered insight on what exactly what was and wasn’t good for different parts of the boat, but throughout the next few paragraphs a few items will be discussed. These items will include different designs of a boat whether they are good or bad, buoyant force, specific propeller types, and efficiency, the end/test results of Steven.
