    Spectra & Flame Tests Intro The emission spectrum is used in modern chemistry to help further studies of wavelengths and the spectrum. When a metal in a compound reacts in a flame and produces a color‚ it helps to show the strongest color in the emission spectrum. The  purpose of performing these operations on the flame was to see how different metals would react. Using a spectroscope‚ it is possible to observe the line emission spectrum produced by sunlight‚ artificial light‚ and various other

    • 3 Pages

    ARTICLE REVIEW Bimetallism refers to a monetary standard or system based upon the use of two metals‚ traditionally gold and silver‚ rather than one (monometallism). This paper focuses on the factors which led to the decline of bimetallism as an international monetary standard. In the late 19th Century‚ bimetallism was replaced with monometallism as countries began to peg their currency to one metal‚ either gold or silver. Many reasons contributed to this. Bimetallism follows the Gresham’s Law

    Experiment: How would an increase in the atomic radii of the metals in period 4 affect the time it takes for a metal to react with HCl. Hypothesis: If Hydrochloric Acid is dropped on all of the metals in period 4‚ then the elements with the largest atomic radii will react faster with Hydrochloric Acid because atoms with bigger atomic radii are more likely to give their electron(s)

    Common Minerals and Their Uses Aluminum The most abundant metal element in Earth’s crust. Aluminum originates as an oxide called alumina. Bauxite ore is the main source of aluminum and must be imported from Jamaica‚ Guinea‚ Brazil‚ Guyana‚ etc. Used in transportation (automobiles)‚ packaging‚ building/construction‚ electrical‚ machinery and other uses. The U.S. was 100 percent import reliant for its aluminum in 2012. Barium A heavy metal contained in barite. Used as a heavy additive in oil well

Though this seems like a good thing on the surface‚ because components are being repurposed‚ unregulated recycling centers burn or dissolve the plastic components to release the precious metals: a process that releases environmental contaminants into the air‚ land‚ and water that would otherwise remain trapped and inert in landfills (Robinson

    A clothing iron‚ also called a flatiron or simply an iron‚ is a small appliance: a handheld piece of equipment with a flat‚ roughly triangular surface that‚ when heated‚ is used to press clothes to remove creases. It is named for the metal of which the device is commonly made‚ and the use of it is generally called ironing. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are

    1.Compare and contrast the crystal structures and crystal chemistry of quartz α-FePO4 and β-FePO4 FePO4 is an extremely distinct quartz as its cation is a transition metal. It is often looked in depth at temperatures ranging from 294K to 1073K. When it is at a relatively low temperature‚ we see the quartz at α-FePO4. It takes on a tetrahedral shape. At higher temperatures‚ the α-FePO4 will transition to β-FePO4 and takes on an octahedral shape. Very importantly‚ the temperature at which this transition
