Abstract: The aim of the experimental investigation was to gather four dissimilar water samples and test them in several different methods to see which water sample had the best quality. The tests that were used were that of: A fecal chloroforms test, phosphate test, nitrates test, pH test, dissolved oxygen test and a total dissolved […]

History of Gators In the early summer of 1965, a university of Florida assistant coach sat down with a team of physicians and asked them to determine why so many of their players were being affected so severely by the heat. Their players’ electrolytes were starting to become completely out of balance. They had low […]

Unsolved problems in chemistry tend to be questions of the kind “Can we make X chemical compound? ” , “Can we analyses it? “, “Can we purify it? ” and are commonly solved rather quickly, but may Just as well require considerable efforts to be solved. However, there are also some questions with deeper implications. […]

Rationalizations is the primary method for purifying solid organic compounds. Compounds obtained from natural sources or from reaction mixtures almost always contain impurities. The impurities may include some combination of insoluble, soluble, and colored impurities. To obtain a pure compound, these impurities must be removed. Each is removed in a separate step in the rationalizations […]

In order to assess the potential environmental impact of four types of soap and two detergents, their properties were analyzed based on specific characteristics and wastewater resulting from vacuum filtration. Essential tests included lather ability, cleaning ability, and solubility to determine the properties of each product. The dirty lab glassware was cleaned by mixing small […]

The purpose of the laboratory experiment was to observe the qualitative aspects of a copper reactions series. The lab report was required to include a purpose, procedure, data/observations, all reactions and side reactions written out with qualitative data beneath each product and reactant except H2O, and a summary. The procedure involved measuring about a leg […]

The question asks us to determine DE, given information about q and w. Plan We first determine the signs of q and w (Table 5. 1) and then use Equation 5. , DE = q + w, to calculate DE. Chemistry, The Central Science, 12th Edition Theodore L. Brown; H. Eugene Lemma,Jar. ; Bruce E. […]

You soak a note in ethanol (alcohol) and it will burn when lighted, leaving the note untouched. This is because alcohol is more flammable, and burning alcohol causes it to vaporize, along with the water present in the solution. This removes heat from the note and prevents it from reaching its combustion point. Materials Bill/Dollar […]

The emotions that you feel are a result of chemical messengers, primarily neurotransmitters. Love, Jealousy, envy, infatuation and infidelity all share a basis in chemistry. Why Onions Make You Cry Marcelo Briton Folio They sit there, so harmless-looking on the kitchen counter. Yet as soon as you cut an onion, the tears begin to fall. […]

Description The students titrate different oils and fats mixed with Volatile against bromine water. Apparatus and equipment (per group) w White tile w Conical flask w Dropper pipette. (Use the type of teat pipette usually fitted to […]

Western society and the effects were numerous and mainly positive. The Industrial Revolution began In England in the sass’s and spread throughout Europe and eventually to America. The extensive effects of the Industrial Revolution Influenced almost every aspect of dally life and human society in some way. During this time period, widespread transportation such as […]

Over the past few decades, the united States has become heavily reliant on using nonrenewable resources. The excessive uses of these resources, such as coal, are extremely harmful to the environment and can be considered responsible for global climate change and the destruction of a once healthy atmosphere. Some companies have claimed to find a […]

Gaseous Diffusion Coefficient Objective To determine gas diffusion coefficient of acetone Introduction because very often process engineering deal with the transformation and distribution of these materials in bulk. One such property is diffusivity. Theory En a concentration gradient exists within a fluid consisting of two or more monuments, there is a tendency for each constituent […]

In the beginning, the narrator Josh finds out a hydro-franking rig has opened near his house. He is afraid that it will pollute his water source, so he starts documenting the effects of hydro-franking on his neighbor’s waters supplies. He goes on a trip to personally document the effects of hydro-franking on people’s homes. When […]

The documentary, “Gas Land”, by Josh Fox, Is a film about the problems with contaminated groundwater due to excessive and unregulated natural gas extraction across the country. In the film, Fox travels all over to talk to many people who have rented out their land to natural gas companies, only to get contaminated water and […]

Using Stoichiometry to Determine Gases Produced In a Reaction Introduction Magnesium is a metal and is the third most commonly used metal by chemists. Some would say it is the least dense structural metal. Its lightness Is often alloyed with aluminum. Magnesium Is also used In racing car wheels called MAG wheels. Many car-manufacturing companies […]

Introduction The purpose of this experiment was to examine the oxidation-reduction reaction of magnesium and a hydrochloric acid solution. We compared the amount of product measured in the experiment to the amount predicted by the balanced equation calculation. To start, we obtained a pre-cut strip of magnesium ribbon, cleaned it with steel wool to remove […]

From this, he contracts Shlgella, which makes him very Ill. This Is all because of dlhydrogen monoxide. Dlhydrogen monoxide quickly and easily transmits diseases through water. If you really care about children, you would take a stand In banning dlhydrogen monoxide. If there were an ingredient list for acid rain, dihydrogen monoxide would be at […]

Before I was able to determine If Dihydrogen Monoxide should be banned from use or not, I had to find out what exactly DHMO was. Dlhydrogen Monoxide, also known as Dihydrogen Oxide, Hydrogen Hydroxide, Hydronium Hydroxide, or simply Hydric acid, is a colorless, odorless and tasteless chemical compound. It has a boiling point of 100C […]

In this laboratory activity you will attempt to produce 1. 00g of calcium carbonate from aqueous solutions of calcium chloride and sodium carbonate. These solutions will be prepared from 2. 01 g of calcium chloride and 1. 06 g of sodium carbonate . Materials: 3 beakers 100 mL graduated cylinder rubber policeman funnel filter paper […]

Plants can make their own food through photosynthesis and then break It down for usable energy through the process of cellular respiration. Analyze and explain how your life might be different If you could make your own food through photosynthesis. First of all If we were to be able to make our own food trough […]

Introduction Overpopulation. Peoples talk a batch about it, but no one truly does something about it. By definition, overpopulation is the status where the figure of organisms exceeds the transporting capacity of their home ground ( Oak, 2009 ) . Talking about overpopulation, we could intend two things. First we could intend that there are […]
