Copper sulphate

While Socrates visited an old friend, Cephalus, Socrates begins asking him and the men around him what justice is. After receiving three definitions from Cephalus, Polemarchus, and Thrasymachus, Socrates debunks them and explains his version of a just society through the myth of the metals. The myth states that one day you awake and find that the Gods have infused you with one of three metals: gold, silver, or bronze. These metals determine your status in society. After comparing the three classes

Copper is a metal that has been used by humans essentially since the beginning of existence as it is said to be only the second metal used by man after gold. Therefore, copper production has been an important part of life for thousands or years and still is today. The copper cycle is an important because it provides a basis for how copper can be recovered from various compounds that it exists in during its so-called “life-cycle” . The life cycle of copper conserves this now scarce metal by allowing

AP Chemistry 12/13/11 Round-Trip Copper Reactions Lab The purpose of this lab was to evaluate our skills of decanting a supernatant liquid without losing the solid and successful completion of a series of reactions. This was done through five chemical reactions involving copper. In this lab, elemental copper was put through five different chemical reactions in order to convert it into different compounds. By the end of the fifth reaction, the copper was back to its elemental state. In the

In 1781, Carl Wilhelm Scheele discovered Tungsten, which is also known as Wolfram. The word Tungsten is used in the United States, but Wolfram is still used in some European countries. Tungsten comes from the Swedish language which means “heavy stone”. Tungsten is a very strong, shiny, gray-white metal that makes up just a tiny fraction of the earth’s crust and is always combined with other elements as compounds. Every tungsten atom has 74 positively charged protons in the nucleus which means

Otzi the Iceman Otzi is a mummified body that was found near the Otzal apes. It was preserved in the ice. Otzi is one of the only preserved bodies that is almost completely preserved. Even after all of that time he had no special treatment to help preserve. It was preserved for about 5,300 years. He was found in 1991 by a couple of tourists on the Italian/Austrian border. When and where did he live? Otzi the Iceman lived about 60 kilometres from where he was found. He was found in Europe in the

METHODOLOGY Site description and sample collection Geographically, Saanich Peninsula is located on the southern end of Vancouver Island, north of the city of Victoria. It has arable land with the mildest climate in Canada. The annual precipitation varies from 635 millimeters in Victoria (city) and increases by 45% in the northern part of the Peninsula, particularly at the airport and nearby areas (Victoria, n.d.). Saanich Peninsula is situated in the south eastern part of the Nanaimo lowland and

The Minerals Among Us: Hemimorphite New Jersey is home to many rocks and minerals. That is because of the state’s location when the North American Continental Plate was Separated from the African plate a long time ago, during Pangea. When the continents broke apart, volcanic rifts rose, pouring new rocks and minerals over New Jersey. One of the minerals found here is Hemimorphite. It can be found in many places in New Jersey, including Sterling Hill, Sterling Mine, and other places in Sussex County

Following the formation of solid copper (II) hydroxide (Cu(OH)2), the solution was heated in order to break the bonds in the copper (II) hydroxide to form copper (II) oxide (CuO) and water (H2O); classifying this process as a decomposition reaction because the reactant was broken down into smaller compounds. While heating the solution, the opaque royal blue color became a clear colorless solution; furthermore, as the solution became clear charcoal color solution began to appear in the solution. The

In this experiment, the scientists are testing which amount of zinc mossy would make a few normal cleaned pennies change their colors into silver when they are placed in the boiling solution of zinc sulfate and water and then turn their colors into the brightest yellow (gold) when they are exposed directly to heat,. The independent variables in this experiment are the amount of zinc and zinc sulfate measured in gram and the dependent variables is the shades of yellow (compared in decimal R,G, B code)
