each hole at various depths and sent them to the Assay lab for the contents of each to be analyzed. After that, blastmaster, Charlie “Red,” would come and analyze the hole and label it with the amount of ANFO to use. ANFO is a mixture of Ammonium Nitrate and Fuel Oil. It is the same stuff that was used in the Oklahoma City bombing. To put the scale into perspective, about 1500 pounds were used in that event, and at the mine, there was, on average 1800 pounds in each of the approximately 400…

Ammonium Nitrate: Oklahoma City Bombing Ammonium nitrate or NH4NO3 is “an odorless, colorless or white, crystal salt produced by the reaction of ammonia and nitric acid” that has become the cause of numerous fatal explosions and hundreds of innocent deaths (The Fertilizer Institute, pp. 1, n.d.). It is most commonly used in the creation of fertilizers. The original problem that led to the use of this chemical was the increasing population and larger demand for food which meant farmers needed to…

increasing the concentration of copper (II) nitrate solution in a voltaic cell affect the voltage produced? Variables: Variables Description of the variable Method of controlling variable Independent Concentration of copper (II) nitrate solution used in each trial of the experiment. N/A Dependent The voltage being produced by the two electrodes which is measured by the voltmeter N/A Controlled Concentration of the zinc nitrate solution. The concentration of zinc nitrate was kept at the same…

stream water there will be nitrates, phosphates, dissolved oxygen, turbidity, different temperatures, and pH levels.The most important factor to stream testing is the temperature of the water. If the temperature increases the amount of dissolved oxygen decreases. (EPA and Staff, 2012)Phosphates are present in the water through human and animal wastes. (Oram, no date) Phosphates are used in laundry soaps, cleaners, industrial effluents, and fertilizers. (Oram, no date) Nitrates are used in…

2.2. Methods 2.2.1. Preparation of econazole nitrate nanoparticles The econazole nanoparticles were prepared by nano-spray drying technique. Weighed amounts of econazole nitrate, carriers and stabilizers (table 1) were dissolved in ethanol (10 ml) followed by spraying through the Buchi® nano-spray dryer B-90 (Büchi Labortechnik, Switzerland). The nano-spray dryer was operated using inert loop B-295 system (Büchi Labortechnik AG, Flawil, Switzerland) operated using nitrogen gas with flow rate of…

Observation My selected artifact is two photographs that Benson took of the organization MOVE, when they were prevalent in Philadelphia. The first, MOVE 78’, depicts 8 members of the group sitting and standing near a fire that is in a large trash can. They appear in front of a dilapidated house. It seems to be either winter or fall, given that many of the members are wearing what seem to be thick coats and the trees are bare. The group consists of mostly males and it is unclear what has been…

Bam! Bam! Bam! goes the gun of a soldier. Have you ever wondered where gunpowder came from? Gunpowder, as well as silk and paper, are just some of many objects traded along the Silk Road that have an impact on our lives today. To begin with the silk road was a trading system and gunpowder was one of the objects exchange on the silk road.Gunpowder is made out of charcoal but it is also known as black powder. Gunpowder is a explosive chemicals which means it is very dangerous. Back to what I was…
