Penelope and Penny are both portrayed the same and have similarities‚ but there are differences between the two as well that make them different and unique‚ and that also ties them together in the end. Penny and Penelope both remain confident throughout their stories. Penny divorces her husband Everett‚ after he is put in jail. With a need to support her and her family‚ she seeks out to find a new husband‚ who has better qualities than Everett; one who she says has to be “bona-fide”. Penny knows what’s

Experiment 1: Synthesis of Copper Compounds Introduction This experiment involves the synthesis of compounds originating from pure solid copper. By applying solubility rules and the reactive properties of substances‚ many compounds which would otherwise be costly to extract from nature are able to be synthesized in the laboratory. Laboratory synthesized may sometimes be more economical than natural extraction‚ however it poses its own problems with the amount of substance that is actually yielded

experimental % of copper (Cu) in a post 1982 cent? In this lab‚ we will determine the % composition of a modern (post-1982) penny by using a strong acid called nitric acid (HNO3)‚ to react and dissolve the zinc core‚ leaving only the copper coating. Once only copper remains‚ we will then compare its’ absorbency to the other five post-1982 penny Cu concentrations made in this lab. INTRODUCTION: Before 1982 the US penny was made of pure copper. Because of the high cost of copper‚ the US government

The Copper Cycle Alexes Montalvo Chem 1500-10 September 26‚ 2012 The Copper Cycle Introduction: The Copper Cycle is a popular experiment used to determine if an element‚ in this instance‚ copper‚ reverts to its elemental form after a chain of reactions. This experiment is very dangerous because of the reactions between the strong acids and bases. In this experiment I performed a series of reactions starting with

Identification of a Copper Compound by Percent Mass Unknown Compound: #9 Abstract: The objective of this experiment was to identify the unknown pure copper salt compound of #9. To do this‚ the mass of copper in the unknown was calculated and then divided by the mass of the whole compound to get the percent copper. The molecular weight was also calculated by dividing mass of copper compound used by moles of compound in unknown sample. The percent copper averaged out to 31.6% while the molecular

: The copper cycle IN TRODUCTION The purpose of the experiment is to recognize that change of state‚ change in colour‚ formation of a precipitate‚ or the evolution of heat are associated with a chemical change; to study reactions of copper. Copper is an element that can be found in nature in a variety of different compounds. The most common natural ore is the sulphide‚ known as chalcocite‚ Cu2S. This mineral is an important source of copper metal because it is about 80% copper by weight

Copper Mining in Zambia Norman Mulimbwa Shachile WHUT‚ Luoshi Rd.‚ International students building No.8‚ Wuhan‚ 430070‚ PR China Abstract The mining industry has been the economic and social backbone in Zambia since the first major phase of exploitation of the Copperbelt ’s Cu-CO deposits commenced in the early 1930 ’s. Since that time a wide spectrum of other metalliferous and non-metalliferous resources have been discovered in Zambia and although exploitation of these has been limited‚ they

LET’S START WITH COPPER CHEMISTRY REPORT 2012 INTRODUCTION: The law of conservation of mass means that the atoms of an object cannot be created or destroyed‚ but can be moved around and be changed into different particles. This law says that when a chemical reaction makes two different atoms into a new product‚ the mass will be the same. Knowing this the mass of the copper should be the same at the beginning and at the end of the experiment. In this investigation we will see

Based on the class data‚ the density of the penny changed dramatically between 1980 and 1985. From 1975 to 1980‚ the penny became 1.40g/mL less dense and from 1980 to 1985‚ the density dropped by 0.626. With this data and the percent composition equation we were able to determine that the second metal in the penny is Zinc with a density of 7.14g/mL. Using scholarly online sources‚ I was able to confirm this data concerning the second metal to be correct. The United States Mint’s website states that
