Copper Reactions Rodney Jay C. Ridao Florencio Louis Pascual Relao De La Salle University- Dasmariñas Dasmariñas Cavite Philippines ABSTRACT The Copper Reactions experiment was demonstrate 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 reagent were being added. It was also demonstrated to practice the common laboratory

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

ABSTRACT Acid Mine Drainage (AMD) problems are the most important environmental problems in sulphide mines especially mines which contain pyrite. Oxidation of sulphides in contact with air and water produces sulphuric acid which reduces the pH of water. The result of these reactions is increase in the solubility of heavy metals and consequently pollution of water resources. The Sarcheshmeh copper mine is one of the largest porphyry copper mines in the world which is located in south-eastern Iran

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

Rocks containing copper compounds (such as copper carbonate) are called ‘copper ore’. Copper is extracted from copper ore by a series of chemical‚ physical‚ and electrochemical processes. Ores can be classed as ‘high grade’ or ‘low grade’ depending on the percentage of copper compounds (e.g. copper carbonate) they contain. After mining‚ the ore is crushed‚ roasted‚ smelted and then electrolysed to extract the copper. Suggested Equipment Boiling tube Samples of different carbonate ores‚ containing

As a nursing student‚ I learned to shave patients in preparation for surgery; as a public health nurse‚ I taught mothers to clean their infants’ umbilical cords with alcohol and showed patients newly diagnosed with diabetes how to wipe the skin with alcohol before injecting insulin. Since then‚ high-quality research has shown that pre-operative shaving increases rather than decreases post-operative infections (Kjonniksen et al. 2002)‚ that cleaning umbilical cords with sterile water shortens the

Equilibrium is the state in which the competing influences of a system are balanced. In this experiment‚ four activities were conducted to study equilibrium namely Equilibrant Force‚ First Condition for Equilibrium‚ Locating the Center of Gravity and Second Condition of Equilibrium. The % Error obtained for the following activities were 14.13% and 2.35% for Activity 1‚ 4.90% for Activity 2 and 7.52% for Activity 4. Friction is the resistance to motion of one object moving relative to another

Case 1 Strengthening the Transportation System By: Charnell Cassette Homeland Security and Defense Professor Aaron Richman Immediate attention needs to be given to transportation for this case study. I have already given my opinion on why and how we have enough security‚ but need versatility. This case study will allow me the opportunity to elaborate on how to strengthen our homelands’ security by tightening up on our nations’ borders and transports
