In this lab‚ we changed copper into various forms using different chemicals and chemical reactions. The purpose of this lab is to demonstrate that the product of a chemical reaction depends on what is present at the time of that reaction. This lab also displays how matter cannot be created nor destroyed in a chemical reaction. In a lab‚ you must always make safety a priority in case of an emergency. In our lab‚ we made sure to wear closed-toed shoes as well as goggles at all times. We also performed

Quantitative Research Quantitative research often is the preferred approach to problem design as results are precise. Many researchers prefer the exact measurement and statistical analysis that quantitative research offers. Observation in quantitative research allows classification and the statistical models built document the outcome of a study. The data collected in a quantitative investigation creates answers in numbers and statistics. Deductive reasoning is used to design quantifiable tools

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. Introduction: Copper is an amazing metal that exists

Copper and Molybdenum Deposits in the United States Copper and molybdenum resources were not recognized as valuable commodities until economic needs demanded the collection and processing of these minerals in large amounts. The most expansive deposits of copper and molybdenum occur in massive low grade ores and are found in intrusive porphyry formations‚ although many smaller sized but higher grade ores are located in non-porphyry areas. The nation has abundant domestic copper ore reserves but

: 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
