Hypothesis With a smaller quantity of water (50mls) and the same amount of Ammonium Nitrate added. After any period of time the mixture will be a cooler temperature than that of a mixture with a larger quantity of water.

plasticizer, curing agent and cross linkers. The commonly used oxidizer is ammonium perchlorate. But its combustion products are environmentally hazardous. Nowadays, ammonium nitrate is gaining great attraction in the field of propellant as a great oxidizer. Ammonium nitrate is an inorganic compound used as fertilizer, oxidizer and also for other applications. AN combined with fuel can be used in gas generators . The ammonium nitrate extracted from demilitarized rocket motors can be used as an oxidizing
were unable to retreat to a safe distance before the explosion. Nearly 200 injuries were also reported to have been treated at local hospitals (Wood, 2013). The explosion was said to be caused by the combination of the fire and large stores of ammonium nitrate fertilizer at the plant. This catastrophic event received immediate coverage from news agencies and journalists across the country. Multiple local, state, and federal Agencies responded to the scene as first responders and post event investigators
!!!What Is Ammonium Nitrate? Ammonium nitrate is a chemical that I first encountered in the chemistry laboratory back in high school. The physical state of ammonium nitrate is typically a white solid, and it soluble in water. The solid can either have a crystalline form or bead form. [{Image src='ammoniumnitratephysicalappearance.png' alt='Ammonium Nitrate: Physical Appearance' caption='Ammonium Nitrate: Physical Appearance'}] The chemical formula of ammonium nitrate is NH4NO3: It has two nitrogen

population of around 2,800 people. During the evening of Wednesday the 17th April of 2013 a massive explosion occurred in the small town. The West Fertilizer Company; which is owned by Adair Grain Inc. which had stockpiles of anhydrous ammonia and ammonium nitrate amongst other agricultural items; was the center and cause of the blast. It is not the first time that an explosion such as this has happened in the state of Texas; in 1947 in Texas city, Texas an explosion that caused nearly 600 deaths had
Ammonium Nitrate Ammonium nitrate was a key ingredient in a bomb that killed hundreds of people. It is an odorless crystal salt that can be either white or grey. It is created by a combination of ammonia and nitric acid. (ammonium Nitrate fact sheet). The primary uses for this chemical are fertilizers and cold packs, as well as military explosives (Mathews J, 2014). Not only is it an oxidizer but under enough heat and pressure, it can explode (ammonium Nitrate fact sheet). This explosive property
very helpful for both injuries and the reducing of swelling and pain. “Inside the plastic container of a cold pack there is a compartment containing solid ammonium nitrate (NH4NO3) that is separated form a compartment containing water.” (Timberlake, Karen, 245) When the ice packed is crushed a reaction occurs between the water and the ammonium nitrate. “The temperature drops to about 4 to 5o C to give a cold pack that is ready to use.” (Timberlake, Karen, 245) Cold ice packs stop the blood flow, which
Masses will travel from all around the world, locally, and throughout the country all to participate in a once a year event. All of the participants take part in a temporary city that is Burning Man, and will light a giant wooden man, burning it to nothing but ashes here in Nevada’s Black Rock desert. This event is described as an experiment of itself and art that followers ten main principles, “radical” inclusion, self-reliance, and self-expression with the purpose of community cooperation, civic
Parker Bell Mrs. West Chemistry, P.2 23 February 2014 The Haber Process The Haber process, otherwise known as the Haber-Bosch process is the reaction of Nitrogen (g) and Hydrogen (g), to produce ammonia; a huge part in the making of plant fertilizers. Ammonia is extremely difficult to produce on a large industrial scale, but the fertilizer made from it is responsible for sustaining one-third of Earth’s population. It was created by a chemist by the name of Fritz Haber, and it was then asked for another
farm machinery. Over the next few days, bags of ammonium nitrate fertilizer, shipped from Nebraska via rail by TCT (Texas City Terminal Railway company) were being loaded onto the ship. By the morning of April 16, 1947, No. 2 hold had 1420 tons of ammonium nitrate while No. 4 had 880 tons. At 8 am that morning, a longshoreman smelled smoke coming out of hold No. 4. He alertly notified his co-workers and they moved several bags of ammonium nitrate fertilizer and found flames between the cargo and
The effects of ammonium nitrate on c-fern spore germination Introduction: Organisms need their own set of nutrients. These nutrients are what help the cell survive so that the whole organism could survive. Organisms have their own set of nutrients. On earth there are three domains of life. These domains are the bacteria, Archaea, and eukarya (Brooker et al. 2013) most of the cells that are being researched and examined are cells in the domain Eukarya because cells in this domain usually exists
Because of this plants are forced to obtain nitrogen in the form of nitrate and ammonium from the soil. Too much nitrate can cause a negative effect on the plant including nitrate toxicity. High levels of nitrate are not only bad for plants but can also be dangerous to animals or humans in their presence. Here I discuss the scientific evidence of the effects of nitrate accumulation on plants and the environment and argue that too much nitrate accumulation can be harmful to its surroundings. Nitrogen is
fertilizer is pure ammonia. It is kept in liquid form under pressure in steel tanks. Three solid nitrogen fertilizers are ammonium sulfate, ammonium nitrate, and ammonium phosphate. Two common phosphorus fertilizers are superphosphate and triple superphosphate. Phosphorous fertilizer is made by treating phosphate rock with sulfuric acid. Potassium sulfate and potassium nitrate are used on crops that are harmed by chlorides. The term straight fertilizer stands for any material that supplies one of
what is now called "the Wöhler synthesis." Wöhler mixed silver or lead cyanate with ammonium nitrate; this was supposed to yield ammonium cyanate as a result of an exchange reaction, according to Berzelius's dualism theory. Wöhler, however, discovered that the end product of this reaction is not ammonium cyanate (NH4OCN), an inorganic salt, but urea ((NH2)2CO), a biological compound. (Furthermore, heating ammonium cyanate turns it into urea.) Faced with this result, Berzelius had to concede that (NH2)2CO
(Singer and Munns). Nitrogen is useful to plants in the form of nitrate because plants can take in nitrate and form organic molecules (Singer and Munns, 193). However, in soils, nitrogen in the form of nitrate (NO3) is considered a "mobile nutrient" which means that it can move easily through the soil to supply the needs of a plant (Singer and Munns, 221). That means it is accessible to the roots of plants, however, it also means that nitrate can be transported through a soil by moving with the water
Qualitative Analysis Purpose: In this lab, we would tests the ions of Mg2+, Ca2+, Sr2+, and Ba2+, and enable each to be identified separately. And by using these observations, we could also identify an unknown. We also would tests the ions of SO42-, CO32-, Cl-, and I-, that also enable each to be identified separately, and to be use to identify the unknown. Safety: Chemicals include toxic. Remember to wash hands after the experiment. Procedure Summary; Part I - Qualitative Analysis
Approximately 1 million new cases of this disease are reported each year in the United States, and public health experts estimate that an additional million or more gonorrhea infections go unreported each year. Although these numbers seem very large, the disease occurs less frequently now than it did in the early 1980s. The rate of infection among young unmarried people between the ages of 15 and 24, however it remains very high. Study results released in 1988 by the National Academy
precipitation. In this lab, solutions of lead nitrate and potassium iodide will be mixed at a number of dilutions. The reactions will then be observed to see at which point a precipitate no longer occurs. Ksp will then be stated as a range of values at room temperature, and the precipitate test tubes will be heated until the precipitate is dissolved so that Ksp may be observed and determined at different levels. In this experiment various solutions of lead nitrate and potassium iodide were mixed at a number
