    Copper-Iron Stoichiometry Lab Report 10/3/12 Abstract: The lab performed required the use of quantitative and analytical analysis along with limiting reagent analysis. The reaction of Copper (II) Sulfate‚ CuSO4‚ mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was

    Marie Remy Lab 02/19/13 Purpose      To explore the cycle of copper through many chemical reactions. What we are going to do is take a piece of copper metal put it through a series of reactions that change it¡¦s state of matter and chemical formula‚ but in the end‚ we will return it to it¡¦s normal solid state. Determine the percentage yield (quantitative). Define what happen at level of electron for oxidation/reduction‚ double replacement‚ neutralization and decomposition. There are five reactions

    Gold Penny Lab Purpose: The purpose of this lab is to convert a regular penny into a “gold” penny. Background: Chemistry is a branch of physical science that studies the composition‚ properties and behavior of matter (www.acs.org). Sodium hydroxide is considered to be a strong base because it breaks up in water. When mixed with certain metals it produces potentially explosive hydrogen gas. Many alchemists believed that doing certain chemical reactions that they would be able

    In order to find the formula of the copper chloride hydrate‚ we had to separate the compound to find the mass of water and copper. To begin this process‚ we evaporated the water and created an anhydrous compound‚ meaning we were left with only CuxCly. By calculating the weight of both the anhydrous and the hydrated compounds‚ we could conclude that the difference in the weights was the weight of the H2O. From this we were able to calculate the percent composition of CuxCly and H2O (see Calculations:
