exo-norborneol was produced by a hydration of alkenes by using an acid and excess water. Hydration of alkenes is the acid-catalyzed addition of water to a carbon-carbon pi bond that leads to the formation of an alcohol. Norbornene is a bridged cyclic hydrocarbon‚ this molecule contains a double bond that induces significant ring strain‚ and therefore‚ it is highly reactive. In order for this reaction to occur‚ equilibrium must be established between the hydration and dehydration processes. To drive

Copper is an element that occurs in minor amounts in the earth’s crust. Estimates of average crustal prevalence are on the order of 0.0058 percent by weight. Deposits considered to be economically recoverable at current market prices may contain as little as 0.5 percent of copper or less‚ depending on the mining method‚ total reserves‚ and the geologic setting of the deposit. Here is the flow sheet on how to process copper from Zenith. Copper Process Flow Sheet: Copper ore is first quarried from

------------------------------------------------- ABSTRACT ------------------------------------------------- The copper reaction experiment was demonstrated by adding the reagents like 16M HNO3‚ Distilled water‚ 6M NaOH‚ 6M H2SO4‚ Acetone‚ Zinc metal and Methanol into the beaker with the copper wire. The experiment was also demonstrated to observe how copper reacts while different reagents were being added. It was also demonstrated to practice the common laboratory techniques such as methods

of MgO‚ using a calorimeter and determining the enthalpy of two reactions. Applying Hess’ law we were able to determine the standard heat formation of MgO. Introduction Energy exchanged in a chemical reaction can either be in the form of heat or light. If light is involved a glow is seen‚ if heat is involved the temperature of the system will change(lab manual page 35). The amount of heat exchanged under constant pressure is called the enthalpy change‚ this can either be endothermic or exothermic

Measuring the Enthalpy change of combustion Abstract This simple experiment is carried out to show the difference in the enthalpy change of combustion between two fuels‚ hexane and methanol. These fuels are individually weighed before and after used as heat source to heat water in a calorimeter. The result is used to find out amount of heat transferred by the fuel‚ amount of fuel used and the enthalpy change of combustion. Introduction Enthalpy change of combustion is the enthalpy change when

HEAT TREATMENT OF COPPER AND COPPER ALLOYS COPPER AND COPPER ALLOYS: Copper and its alloys are widely used in many products that are used in our everyday life. They have excellent properties such as electrical and thermal conductivity good strength. They have high corrosion resistance and fatigue resistance. Copper is a non-magnetic material. Pure Copper is soft and used widely in wires and cables and is extensively used for passage of electricity. Copper is used in the building construction.

Chemistry Internal Assessment: Determining the Enthalpy Change of a Displacement Reaction AIM: To determine the enthalpy change for the reaction between copper(II) sulfate and zinc. BACKGROUND THEORY: Bond breaking is endothermic while bond forming is exothermic. The reaction between copper(ll) sulfate and zinc is exothermic as the energy required to form the bonds of the products is greater than the energy required to break the bonds of the reactants. In an exothermic reaction‚ heat is

This experiment contains three separate procedures in which Aluminum Potassium Sulfate(Alum) will be melted‚ massed out and mixed with Barium Nitrate‚ along with distilled Water. Procedure one we completed two trials of melting two separate 0.01g of Alum and making a comparison to the literature temperature of 92.5‚ to do this we attached an Alum filled capillary tube to a thermometer and inside a beaker placed over a Bunsen burner. Procedure two consisted of placing 2.00 grams of Alum into a crucible
