Title: The Densities of Liquids and Solids compound.


Abstract:
In this experiment we will determine the density of liquid and a solid by two quantities of mass and the volume of a given quantity of matter.To properly measure density,we need container whose volume is known to a high degree of accuracy. This container is known as a flask and stopper.


Introduction:

Density is the ratio of the mass of a substance or object to its volume. At any given temperature, the ratio of mass to volume is characteristic for a given substance.Common liquids and solids of various densities are layered in a beaker. The liquids form different layers and the solids float at the interfaces between them. This demonstrates that a solid's ability to float or sink depends on its density relative to the liquid it is in.The physical properties of a pure substance are those that can be measured without changing the composition of the substance. The density of a substance is an intensive property of the substance. The property is independent of the mass of the substance ( intensive ). The density of a substance is a measure of the mass of the substance per volume occupied by the substance. The density of solids and liquids are generally given in units of grams per milliliter, while for gases the units are grams per liter. We will be determining the density of water, the density of an unknown liquid, the density of a regular solid and the density of an irregular solid.The Density of solid, liquid is the amount of mass it has divided by the volume it occupies. Solid has got lots of regular spaces between its molecules so the same number (mass) of water molecules is less dense than the same number (mass) of water molecules when they are all melted into liquid water. that's why solid ice floats on water, because the same volume of ice actually…...

...LIVESTOCK INDUSTRY Prepared by Kate Buckner Secretary of McAlester Union Stockyards Report Distributed July 24, 2013 Prepared for ENG 3903 Technical and Professional Writing Dr. Mark Spencer Southeastern Oklahoma State University ABSTRACT This report looks at the history of the livestock industry and examines how it has changed throughout the years. People for the Ethical Treatment of Animals, the Humane Society of the United States, and other activist groups have continually tried to cast a negative shadow on the livestock industry; however, with groups such as Livestock Marketing Association, the livestock industry has flourished. The issue of horse slaughter has recently become a big issue for the livestock industry. INTRODUCTION The livestock industry has provided beef to the American public since cattle were introduced to our country in the early 1900’s. It is an indisputable fact that the human population requires enough protein to survive and maintain good health. The livestock industry has come a long way in the last century. It has survived droughts, depressions, recessions, fluctuating economies, as well as pressure and criticism from several organizations, such as PETA (People for the Ethical Treatment of Animals), HSUS (Humane Society of the United States), the EPA (Environmental Protection Agency), and other activist groups.

Formal Lab Report 2

...Sean Cui Biology Formal Lab Report 2 Intro Throughout this lab, the main topic is genetic transformation. Genetic Transformation is a phenotypic change caused by genotype change from transferring foreign genes into an organism. This lab is to transform the bacteria E.Coli with the GFP gene (Green Fluorescent Protein). GFP makes organisms glow in the dark with UV light, similar to jellyfishes.GFP will be transferred into E.Coli through the use of recombinant DNA, or simply a vector. A vector is a plasmid that transfers foreign DNA into cells. Bacteria can transfer plasmid to other bacteria so they can survive and adapt to the environment they are in. The pGLO plasmid includes the GFP gene (allows bacteria to glow), Beta-lactamase (resists ampicillin), ORI sites (allows bacteria to self replicate), and AraC (allows induction of GFP gene). Materials and Methods: In this lab, first there will be two micro test tubes, one labled pGLO+ and the other pGLO-. Using a sterile transfer pipet, transfer 205 microliters of CaCl2 into each tube. Then put the tubes on ice. Then use a sterile loop to pick up a single colony of bacteria from the starter plate. Put the colony in the pGLO+ tube and spin the loop. Then put the tube back in ice. Repeat this for the pGLO- tube with a new sterile loop. Next use a new sterile loop and get some DNA stock. With the loop, immerse it in only in the pGLO+ tube. After that, incubate the tubes in ice for 10 minutes. Label one plate LB/amp...

...I. Introduction In 2012, The University of South Alabama presented the USA Archaeology Museum. Located directly beside the Humanities building, the museum provides visitors with the history of Mobile dating back 14,000 years. At the museum, one can view the indoor exhibits, interact with archaeological technology, and also enjoy the display of Mobile’s native plants on a trail located outside of the museum. A. Purpose The purpose of this report is to evaluate the positive and negative features experienced in my visit. The results are based on my first visit to the Museum. II. Scope and Research Method I have been to multiple museums in various states across the country. However, this was the first time I had experienced the history of Mobile on display. I visited the Museum on Thursday, November 6, 2014 at 3:00 p.m. This report is based on what I observed at that time. My observation was based on four main features including appearance, layout, educational worth, and user friendliness of the museum. The scoring system used is based upon my experience at the USA Museum compared to the other museums I have visited. The scale ranges between one (lowest) to five (highest). C. Limitations This observation was made from one initial trip at three o’clock to the museum. I am unaware of any activities that may take place at any other time. I am very familiar with the external appearance of the facility due to traveling past it to and from class. D. Preview...

They are responsible for the organization of soccer’s major international tournaments, notably the World Cup. It was founded in 1904 in order to oversee international competition among many national associations of many European countries. Its headquarters are located in Zürich, Germany and its current president is Gianni Infantino. FIFA does not control the official rules of soccer, but it is responsible for the administration and promotion of a myriad of tournaments which generate revenue from sponsorships. FIFA has had substantially high revenues since 2013 of over a billion dollars and net profits reaching over $70 million, along with over a billion dollars in cash reserves. Since FIFA is such a powerful association and is responsible for providing the world’s most watched sporting event, it has been linked with corruption, bribery, and alleged vote-rigging. Such corruption has brought about the questioning of former FIFA Presidet, Sepp Blatter and the awarded 2018 and 2022 World Cups to Russia and Qatar.

...Identification and Synthesis of an Unknown Ionic Compound 3/24/16 Department of College of Natural Science, Michigan State University, Farm Lane, East Lansing, MI 48825 Chemistry 161, Section 10 Dr. Joseph Ward Abstract The goal of this experiment is to identify an unknown compound. To identify this compound a series of test were performed to find the chemical and physical properties of the unknown compound. The test performed; flame test, solubility test, halide test, acetate test, ammonium test, nitrate test, sulfur test, carbonate test, calcium test and pH test. When the flame test of the unknown resulted in a brick red color, it was determined that the unknown contained calcium. Another calcium test was tested and proved that the unknown was calcium. Since the unknown is dissolvable in water, CaCO3 was no longer a possible candidate because it is insoluble. The pH test for the unknown was 5 whereas the pH for calcium chloride is 8 and the unknown tested negative for halide, therefor calcium chloride was not an option for the unknown as well. The last calcium compound left was calcium nitrate which also had a pH of 5 and a brick red flame test color. Introduction There was an unidentified white compound found in the lab. The goal of the experiment was to identify what the unknown compound is and how to dispose of it safely. In order to find this information, the compounds chemical and physical properties needed to be determined. This was a...

...Determining Enzyme Specificity in chemical reactions Introduction Enzymes are proteins that catalyze chemical reactions by speeding up the rate of the reaction and are usually named for the substrates they work on most with –ase suffix e.g. Substrate- Lactose, Enzyme- Lactase. Every reaction requires activation energy to begin and without the aid of enzymes chemical reactions require high levels of activation energy and would be too slow to support life within cells. Since every chemical reaction that occurs in the cell produces a chain reaction that triggers other reactions enzymes help set a pace that makes things flow at a rate that ensures all reactions are timely and therefore do not hinder other progressive reactions. However, in order to ensure that there is no confusion within the cell, DNA provides the coding for each enzyme with a specific active site onto which only one or two particular substrates can attach. Based on this information it was hypothesized that Lactose is the specific enzyme for Lactose. In this experiment the enzyme Lactase was used on the substrates Lactose and Maltose to find out which of the two it would catalyze in the production of Glucose a molecule common in both substrates. Materials and Methods Two microfuge tubes one labeled Lactose, and the other Maltose. Using a clean plastic pipette 500ul of Milk (the source of the substrate Lactose) was added into the Lactose microfuge tube up to the 0.5 line and using another clean plastic...
