This experiment was performed to demonstrate a cycle of chemical reactions involving copper. This lab will start with copper as a reactant in the first reaction through a series of five chemical forms of aqueous phase reactions and ending to calculate the percentage of recovered solid copper as a product in the last reaction of the experiment. The experiment resulted in a percent recovery from the cycle of copper reactions of an increase to 139%. . Introduction: The purpose of this experiment is

Bowens Reaction Series Mineral occurrence in igneous rock is most simply explained by Bowen’s reaction series. Norman Levi Bowen discovered the series of reactions while studying the process of crystallizing minerals in Washington‚ D.C. in 1928. In order to best express his findings to his scientific brethren‚ Bowen created a visual display based on when and under what conditions each silicate mineral crystallized. This is extremely important to geologists because it helps them to easily understand

This lab focused on three factors affecting reaction rates‚ temperature‚ surface area‚ and concentration. Our first experiment (table 1) looked mainly into the effects of temperature on the reaction rate. To see how different temperatures would change the reaction rates we had three flasks all containing varying temperatures of water(H20). One with cold water (4°C)‚ one room temperature (21°C)‚ and one with hot water (44°C). In each flask‚ we dropped one tablet of Alka-Seltzer‚ all within 0.008 grams

The Three Crusades There were three Crusades and they all took different routes from western Europe to Palestine. THE FIRST CRUSADE - The first crusade began in A.D. 1095. Pope Urban II mounted a platform outside the church at Clermont‚ France. The crowd shouted "Deus vult!" in response to the pope’s plea. Knights and peasants alike vowed to join the expedition to the Holy Land. For knights‚ the Crusade was a welcome chance to employ their fighting skills. For peasants‚ the Crusade

Clock reactions If you choose a project that explores the kinetics of a chemical reaction you will need a way of measuring the rate of the reaction. Clock reactions provide an interesting way of doing this for some systems. In a typical reaction the first part of a graph showing the concentration of product against time is approximately a straight line (see Figure 1). If you choose any value of concentration that lies on this straight line (say c1) the initial rate of reaction can be found

Three arguments Word critical argument analysis essay‚ focuses on three professional essays and how these authors construct their arguments using opinion and evidence. There are many different ways in which authors can construct their arguments. In the highly controversial topic of legalizing marijuana I found three very different styles of arguments in which the authors backed up their opinions with facts.
