that is available at gun shops and sporting goods stores.” Our text went on to say that “Pyrodex is a pyrotechnic composition that is best described as replica black powder. it does not contain nitrocellulose, nor is it a smokeless propellant. rather, it is a propellant designed for use in percussion and black powder cartridge arms that are in good shooting condition. although Pyrodex is not black powder, it does smoke.” Once again, I had no knowledge of what Pyrodex was prior to this lesson. I…

converted into fluorine and chlorine compounds (known to be ozone scavengers). The aerosol industry immediately responded to their work. In 1977, CFC propellant usage begun to drop by three-quarters because the public realized that there were many substitutes for CFCs, like roll-on-antiperspirants and pump sprays for kitchen cleansers. The ban of propellant took effect in 1979. In 1985, the British…

percent sulfur. This ratio of 75:15:10 ratio of saltpeter, charcoal and sulfur is commonly known as black powder. Together, the mixture of these three compounds in a proper ratios create a powerful explosive. The reason gunpowder became the primary propellant for artillery and guns for over 800 years was that gunpowder didn’t require exposure to air to burn. As saltpeter decomposes at high temperatures, it provides oxygen for the reaction.…

kerosene (RP-1) propellant for fuel and are capable of providing…

When the nozzle is pressed down the pressure allows for the propellant chemicals such as Propane and Dimethlyl Ether to force out the product. In a can of hair mousse contains many gas particles that are in a small area which makes the pressure force larger and easier for the mousse to come out. Since we know that…

When examining the history of most chemicals, there is often various arguments for and against that specific chemical. For instance, most prescription drugs contain side effects, which are unwanted symptoms caused by that drug. However, the beneficial effects of the drug far outweigh the side effects that accompany it. In contrast, such is not the case with chlorofluorocarbons (CFCs), which are chemical compounds containing chlorine, fluorine, and carbon atoms. Although they were considered as a…

HPLC column can be categorized into two types • Reverse Phase • Normal Phase 3.4.1.1. Reverse Phase Chromatography Reverse Phase system has a non-polar stationary phase over which polar solvents are used as mobile phase; it is generally used for separation of polar species. 3.4.1.2. Normal phase chromatography Normal Phase system has a polar stationary phase over which non-polar solvents are used as mobile phase; it is generally used for separation of non-polar species.[38]. A detection…

Chuqiao Sun 1335349 Sunc8@uw.edu Writing Project Space craft finally approaching Jupiter. With NEXT, which is NASA’s new propulsion system using xenon propellant with blistering speed of up to 90,000 miles per hour, the crew traveled to Europa in about 200 days. NEXT provide same amount of energy with 860 kg of xenon propellant compare to 10,000 kg propellant in old technology and have five and a half years life time. To save food, water, energy, and space for long distance space travel, all…

Argon is the element i picked for the project. Argon is a chemical element with symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. Argon is the most abundant gas in the earth's atmosphere. It makes up 1.28% of the atmosphere. It was one of the first noble gases to be discovered. It is a colorless, odorless, and non-toxic material in all three of its states. Henry cavendish proposed in 1785 that argon might exist. Lord rayleigh and sir william ramsay…

the world of rockets. Russian Konstantin E. Tsiolkovsky published Rocket Equation in a Russian aviation magazine in 1903.The equation involves the speed of the rocket and the mass of the rocket, in addition to how fast gas exits and the amount of propellant is present. Robert Hutchings Goddard is credited with creating and building the world’s first liquid fueled rocket. “He published his classic treatise, A Method of Reaching Extreme Altitudes, in 1919.” (Lehman). Goddard’s book consisted of…
