What Is Hydrazine?

Theophylline is a bronchodilator used in the treatment of asthma, it has a low molecular weight of 180.2. It is slightly acidic, when in a saturated solution of water and has a pKa of 8.81.

The following laboratory experiment calls for a moderate understanding of what a hydrate is, what its properties are, and how altering a hydrate’s chemical structure may cause the release of both water and acidic vapors. A hydrate itself is a chemical, typically a crystalline salt, which incorporates water (H2O) into its chemical structure. For example, the compound CoCl2 is merely cobalt (II) chloride, however, take the original compound and attach a water molecule and it becomes CoCl2 + 6 H2O. In other words, the original cobalt (II) chloride is now cobalt (II) chloride hexahydrate.

For this experiment we analyze the percent water in a crystalline hydrate. By examining the percentage we then are able to identify the changes in compound and compare them to that of unknown possibilities. In order to identify what hydrate we’re experimenting with, it must first be weighted using an analytical balance and record its initial state. To begin the heating process, the hydrate is moved back and forth over a flame at a 45 degree angle in order to remove any water within the hydrate. Thus it becomes a anhydrous residue after heat is applied. In order to achieve a constant weight of 0.002g or less, the anhydrous needs to be heated several times in order to eliminate most of the water contained. By calculating the the initial and final stage of the hydrate, the percent water will be determined. Finally, by comparing the mass of water lost from the unknown hydrate, the compound can be referenced from a list of unknowns.

My group did Atrazine and I came to quickly discover that it wasn’t just an herbicide farmer’s used. There was so much more to the story and it was more than a controversial topic, it involved a major feud between two sides. The company Syngenta, who primarily produces atrazine, and a now well-known scientist, Dr. Hayes. With Syngenta being the primary producer of the product it’s a no brainer that they would suffer if it were to be taken off the market. Dr. Hayes has published research of his own that shows that if the chemical gets into our drinking water it can have negative affects on amphibians. There are also speculations that it might affect humans as well. Dr. Hayes actually did research for the company on the product, but when they wouldn’t let him produce what he found he cut ties with the company and had others help in publish what he had found. This spiked the feud, or what I like to call war, between the two. For the presentation we had to remain neutral and leave out our opinions and I found this hard to do because I was so strongly against the usage of the product from doing research. In this paper I will go into detail about my stance on the topic, why I have taken this side, and why this is such a controversy.

Sulfanilamide, also referred to as sulfa, was a drug sold in powder and tablet form used to treat infections such as pneumonia, meningitis, and strep throat. In the 20th century, these bacterial infections could easily take the life of anyone. That is why sulfanilamide became so popular throughout the country. Sulfanilamide was invented by a German microbiologist, Gerhard Domagk. It was a red dye derivative that he had discovered that would cure the contagion. The drug was safe until a salesman from Bristol, Tennessee recommended that they produce a liquid form of the drug to make swallowing easier. The company’s head pharmacist and chemist was Harold Cole Watkins, he found out that sulfanilamide was soluble in diethylene glycol, commonly found

What must first be noted is that methane clathrate is a solid hydrate compound. A hydrate is typically a crystalline compound in which water molecules are chemically bound to another element.

Sulfamethoxazole-Trimethoprim (SXT) has the trade name of Bactrim. The generic name for SXT is Sulfamethoxazole/Trimethoprim. This is a synthetic antibiotic which was produced by Bayer in 1968. It falls under the class of sulfonamide. Sulfamethoxazole works by blocking the bacteria which have the ability to make folate. SXT is used for diseases such as MRSA, cholera, and pneumocystis pneumonia. It it most effective in combating both gram-negative and positive bacteria. Side effects include things like nausea, diarrhea, rashes, and vomiting. Sulfamethoxazole-Trimethoprim can be given in two different ways either by injection or it can be taken orally.

Methotrexate is a competitive inhibiter of binding of dihydrofolic acid (FH2) to the enzyme dihydrofolate reductase (DHFR). METHOTREXATE is a structural analogue of folic acid which make it can easily bind to the same receptor. DHFR is responsible for reducing FH2 to folinic acid (FH4), the active intracellular metabolite. Thus, METHOTREXATE decreases the amount of intracellular FH4 available and affects the metabolic pathways within the cell that are FH4 dependent. These pathways include pyrimidine metabolism and purine, polyamine synthesis and amino

CCCP, carbonyl cyanide m-chlorophenyl hydrazone, is a potent uncoupler of electron transfer from ATP synthesis by blocking formation of the electrochemical proton gradient generated during electron transport by the respiratory chain carriers. This disruption of the photosystem assembly in cyanobacterium Synechocystis 6803 has been used as a strategy for the accumulation of distinct transient assembly intermediates. This has provided a critical test of the possibility that partially assembled complexes can be isolated from the CCCP-treated cells in a form in which transient associations with participating assembly factors are retained. In our experiment, Rba. sphaeroides will be used which consists of rows of reaction center-light- harvesting

Ketamine, sold under the brand name Ketalar among others, is a medication mainly used for starting and maintaining anesthesia. It induces a trance-like state while providing pain relief, sedation, and memory loss. Other uses include for chronic pain and for sedation in intensive care. Heart function, breathing, and airway reflexes generally remain functional. Effects typically begin within five minutes when given by injection with the main effects lasting up to 25 minutes.

Sustainability “Sustainability is the ability to continue a defined behavior indefinitely.” The sustainability has three mainstays which are environment sustainability, economic sustainability and social sustainability. The environment sustainability is the capacity to keep renewable energy supply and reduce the consumption of non-renewable energy. The social sustainability is able to give full play to superiority in community, like a country, they can get unlimited public welfare from social sustainability. The level of economic production is sustaining by the economic sustainability which is the other ability for sustainability.

Roderick Usher is our main character in the Edgar Allen Poe’s horror story “The Fall of the House of Usher”, who is described in the story as gloomy and mysterious. In the poem being bother by his hyper senses, Roderick are seemed with less energy and pallor of the skin than the narrator found him. (Poe, 17) Although the narrator puts a lot of effort to uplift his mood, he still seemed very depressed and nervous.

Imagine looking up surrounded by guns with blood on your face and hands. Then, you realize that the blood was on you from eating someone. After several days, you understood that all of this was from your new bath salts addiction. This was one of the story that was reported about a man under the influence of bath salts. What is Bath salts? According Airuehia, Young Walker, and Nittler (2015), bath salts refers to products that may be a combination of one more mixtures of different synthetic cathinone, which may be known as methylenedioxyprovalerone (MDPV) and mephedrone. Bath salts are human-made stimulants chemically related to cathinone, a substance found in the khat plant. The above authors also mentioned, khat is a plant native to East

In hot climate, you need icy beverages to keep hydrated including any semblance of ice espresso, ice tea, squeeze, or anything frosty you can put your hand on. At the point when the climate is chilly, you hunt down hot beverages such as: tea, espresso, cappuccino, natural beverages, or whatever other beverage to caution yourself with. In any case, you will require a spot to put your beverage on while you are drinking. That place is the napkin; it is put on tables to shield their wood surface from soggy, stains, or scratch.

In life there are many obstacles a person will face, such as school, work, family and time.
