used for filtering rather than for boiling water. The material of kettle was then switched from iron to copper because it conducted heat more efficiently. It was one of the great metals and copper was a common of the 19th century. Cast Iron Kettle (3) Stovetop Kettle A stovetop kettle is a roughly pitcher shaped metal vessel use to fill water and boil water on a stovetop or hob. Sometimes stove-mounted kettles also have a steam whistle which indicates when the water has reached boiling point

bleach. Electrolysis is also used to extract reactive metals like aluminum and the purification of copper. [1][2] Electrolysis has many benefits like bleach. Bleach is usually used in cleaning household materials‚ and to whiten/lighten or clean stains on white cloth. Bleach is also used by ladies on their face to make their face white and bright. Other than that there is electroplating. Electroplating is the coating of a metal over the other metal. Electroplating is done for a few reasons to benefit

three types of groups; mainly metals‚ polymers and last but not least ceramics. Each and every type of the aforementioned group has their very own specialties‚ properties‚ structures and other characteristics. They all play an important role when it comes to selecting materials for the creation of a new equipment‚ device or product. Each group are observed or studied physically‚ mechanically‚ electrically‚ thermally‚ magnetically‚ optically and chemically. Metals are one or more metallic elements

What portion of the periodic table is responsible for the color observed? The metals portion. B - In cooking over an open flame‚ a yellow flame is often observed when some food is spilled into the flame? What is most likely responsible for the yellow flame color? Barium is most likely responsible. It burned yellow over the flame

In this lab we synthesized trans-[Bis(inosinato) palladium(II)] for IR analysis. After completion of the reaction 84.4% of the product was collected. IR spectrum of the product and inosine was analyzed to determine how the inosine is bonded to the metal‚ palladium. From the IR analysis‚ it was determined that when inosine reacts with palladium‚ a shift of about 65 cm-1 in the carbonyl stretch was observed. Introduction: In this experiment‚ trans-[Bis(inosinato)palladium(II)]‚ was synthesized

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

The brass alloy we are experimenting on is called Muntz Metal. Muntz metal is 60% copper‚ 40% zinc and a hint of copper [http://en.wikipedia.org/wiki/Muntz_metal] (accessed 4/10/12). Muntz metal was developed as an alternative to expensive‚ heavy copper. It is comprised of about 60% copper and about 40% zinc‚ with a small amount of iron. The finished product actually is considered a form of brass‚ but it has maintained its name of Muntz metal. [http://www.wisegeek.com/what-is-muntz-metal.htm] (Accessed

Air Resistance Lab G Luhman‚ Mary …. Abstract: The acceleration of objects dropped from about 2 meters was found in order to derive the Reynolds Number. The effect of changing weight‚ shape‚ and radius of the objects (balloons) were tested independently such that it would be clear under what criteria either laminar or turbulent air flow is prevalent. • Introduction The difference between two models‚ laminar and turbulent‚ of air resistance may seem trivial the difference is can be seen
