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

increasing‚ the demands for longer battery life are also increasing. These batteries need to be recharged or replaced periodically. It is a hassle to charge or change the battery after a while‚ especially when there is no power outlet around. Therefore‚ our team is inspired to design a wireless battery charger. This wireless battery charger is expected to eliminate all the hassles with today’s battery technology. Wireless power is the transmission of electrical energy from a power source to an electrical

is that‚ since its acquisition‚ Duracell has become a drain on the financial performance of Gillette. The board needs to decide what should be done to turn Duracell around and restore Gillette to a dependable financial performer. 2. How is the battery industry (you can use five forces analysis to answer this question)? Has it been changing? If yes‚ how? Overall‚ the industry is very attractive. New entrants realize the potential of snagging a piece of a highly profitable industry that produced

process of electrolysis is the interchange of atoms and ions by the removal or addition of electrons from the external circuit. The desired products of electrolysis are often in a different physical state from the electrolyte and can be removed by some physical processes. For example‚ in the electrolysis of brine to produce hydrogen and chlorine‚ the products are gaseous. These gaseous products bubble from the electrolyte and are collected 2 NaCl + 2 H2O → 2 NaOH + H2 + Cl2 A liquid containing mobile

The subject I chose for my topic report is “ Competing in the Adult Night Club Industry “ . The subject sparked my interest when I over heard a classmate saying she wanted to own a “strip club”. I also had thoughts of one day opening my own “gentlemen’s club”. Typically when you think of a “strip club” you think of a low class‚ raunchy‚ place filled with criminals‚ but contrary to some beliefs that isn’t always the case. There is an upscale adult entertainment venue called a “gentlemen’s

6: The Copper Cycle CHEM 101 Lab-M/630 As an investigation of the copper cycle lab group 6 conducted an experiment on 6 October 2014 at Arizona State University laboratory that would demonstrate the cycle of reactions that copper (Cu) can produce when introduced to with other substances/reactant. The purpose of the investigation was to notice the transformation of a specific quantity of copper wire (g) as it undergoes its coordination reactions until a reduction method would yield copper (Cu) again

A Sequence of Chemical Reactions: Transforming Copper Briefly describe. a) Why must you carry out the oxidation of Cu with HNO3 in a fume hood? Concentrated nitric acid is a toxic oxidant. Avoiding skin contact or inhalation is highly important. The reaction between Cu and HNO3 produces NO2‚ a toxic brown gas; therefore working under the fume is necessary in order to prevent inhaling the toxic gas. b) Why you should be particularly careful when you work with 3 M H2SO4 solution?

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

Synthesis and Decomposition of Zinc Iodide Partners: Sonya Pasia and Kristen Kobayashi CH 085-01 20 September 2011 Zinc Iodide (ZnI2) was an interesting binary compound to experiment with. In this experiment‚ weakly acidified water (25mL distilled water with 18 drops 5M acetic acid solution) was used as an aid to bring molecules of the zinc and iodide atoms together‚ by dissolving iodine molecules‚ so that bonding would transpire to produce a reaction. Deprived of water‚ the Zn and I2
