------------------------------------------------- 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

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

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

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

CULINARY CALCULATIONS The Standardized Recipe The standardized recipe is the hallmark of the foodservice industry today. The information contained in the standardized recipe ensures that a consistent product is always served to the guest. A consistent product means the look‚ taste‚ texture‚ and portion size of the menu item is the same each time the item is prepared and served‚ regardless of who is in the kitchen on a given day. Each standardized recipe has a specific yield‚ which can be increased
