Conclusion: (Identity‚ % error‚ other evidence‚ how to improve) The identity of Unknown A is the compound cobalt(II) chloride hexahydrate (CoCl₂•6H₂O).This is justified by the similarities in color of red-purple crystal like grains‚ which is significant in identifying the product out of the eight suggested identities. Only two had similar characteristics which were CoCl₂•6H₂O and CoSO₄•6H₂O. Before unknown A was heated‚ there was a notable common physical property of the substance being red crystal

Transuranic Elements and their Production Transuranic elements are elements that have an atomic number greater than 92. Transuranic elements have been synthesised in nuclear reactors or in high-energy particle accelerators. Neptunium and plutonium were the first transuranic elements to be synthesised in 1940 by Glenn Seaborg’s research team in the USA. Uranium 238 is bombarded with neutrons produced by the nuclear fission of U-235. Initially an isotope of uranium (U-239) forms which decays

Andy Yowell Geoffrey Bennett Principles of speech 4/20/2015 General Purpose: To argue Specific Purpose: To argue the point that green cars aren’t any better than non green cars. Thesis Statement: The government and certain car manufacturing companies shouldn’t be promoting energy conserving vehicles as zero emissions vehicles because 1) the process of manufacturing electric cars pollutes the environment; 2) recharging the car uses a tremendous amount of fossil fuels; 3)The cost to manufacture

tris-hydroxylmethyl amino methane. Examples of primary standards for titration of bases are: Potassium hydrogen phthalate and potassium hydrogen iodate Examples of primary standards for redox titrations are: Potassium dichromate (K2Cr2O7 )and sodium oxalate (Na2C2O4) A secondary standard is a standard that is prepared in the laboratory for specific analysis. It is usually standardized against a primary standard. Standard has the following uses in a chemical analysis; 1. It provides a reference which

RESULTS AND DISCUSSION In the Iron (II) - Silver Ions System the reaction had a balance chemical equation of Fe2+ + Ag+ Fe3+ + Ag(S). The process if centrifugation is used in this part of the experiment to be able to separate the supernatant and the precipitate. And the supernatant will be used to test for the presence of Fe2+‚ Ag+ and Fe3+ in the solution. Results showed that there is a positive presence for FE 2+‚ Fe3+ and Ag+ because of the visible change of color of Prussian blue precipitate
