Copper Sun‚ by Sharon Draper‚ is a telling of the story of a fifteen-year-old girl named Amari. It tells about her being taken from her home in Africa‚ being sold into slavery‚ her tales in the house she was sold to‚ and her escape. Many strong emotions are displayed‚especially through Amari‚ two that were very brightly displayed were fear and sadness. Fear is a distressing feeling or emotion‚ everyone will feel fear at one point‚ it’s caused by impending danger‚ evil‚ pain‚ etc. During the story

At present‚ the raw materials to refine copper in China mainly are towanite‚ chalcocite‚ bornite‚ malachite and etc. According to the technical conditions of smelting‚ the copper ore can be divided into three classes based on the proportion of copper oxide and copper sulphide‚ that is‚ sulfide ore‚ which contains less than 10% copper oxide；oxidized ore‚ which contains more than 30% copper oxide; mixed ore‚ which contains 10%~30% copper oxide. Copper is one of earliest metals that be found and used

many chemical qualities of copper ‚ by using many solutions that enable copper to undergo chemical changes that will take copper from a metal back to its original state. This is done using cooper‚ Concentrated HNO3‚ 6 M NaOH ‚ Bunsen burner‚ 6 M H2SO4‚ Mg ribbon‚ and two test tubes. The techniques used in this lab which is cleaning glassware‚ disposing of chemicals ‚ measuring mass ‚ centrifugation ‚ venting gases‚ and test tube over a “cool” flame.

Lab: STOICHIOMETRY The reaction of Iron with Copper(II) Sulfate Purpose: In this experiment we will use stoichiometric principles to deduce the appropriate equation for the reaction between metallic iron and a solution of copper (II) sulfate. This reaction produces metallic copper‚ which is seen precipitating as a finely divided red power. Materials: Flask beaker Copper solution Balance Hot plate •150 ml beaker •1 gram of iron power

Determine the concentration of an unknown copper (II) sulfate solution by using colorimeter Introduction: The concentration of the solution also alterations the proximity of the solution. For example‚ the more focused concentration will frame to be denser than more weakened concentration of copper (ii) sulfate. This implies there is a connection between the concentration of an solution and its absorbance. Along these lines‚ this test is set up to discover the kind of connection between the concentration
