The Copper Cycle Alexes Montalvo Chem 1500-10 September 26‚ 2012 The Copper Cycle Introduction: The Copper Cycle is a popular experiment used to determine if an element‚ in this instance‚ copper‚ reverts to its elemental form after a chain of reactions. This experiment is very dangerous because of the reactions between the strong acids and bases. In this experiment I performed a series of reactions starting with

Chemical Reaction of copper compounds Introduction: In this experiment‚ the objective was to conduct a series of chemical reactions that contain copper or copper compounds. That is to say that the products of each chemical reaction were used in the next reaction. The process starts with a solid copper wire dissolved in nitric acid and the end product is copper powder. The product which was used from the previous reaction is the limiting. In the initial step‚ the solid copper is the limiting reactant

Copper Cycle Summary During the copper cycle lab‚ my partners and I performed a series of reactions on copper powder and observed the changes it underwent. For the first step‚ we mixed nitric acid and copper powder‚ and noticed that a yellowish brown gas emerged‚ along with effervescence. The red solid disappeared and became a blue liquid. We know that we produced copper nitrate‚ nitrate gas‚ and water because the only two blue solutions in “A New Language” are copper sulfate and copper nitrate

Copper Pipe | Plumbing Katy Copper pipe has been a top pipe choice for homeowner’s and business owners alike for over 7 decades. Due to its long term performance‚ and known history‚ it remains a highly popular pipe material. So popular‚ in fact‚ that over 80% of homes are plumbed with copper pipe. However‚ it does face growing competition from lower cost plastic options‚ such as PVC‚ CPVC and PEX. That said‚ copper may be the best option for your home’s plumbing in Katy. In the following‚ we will

from a pure copper mug is considered very beneficial for our well-being. By storing water in one of the copper mugs‚ minute traces of copper will start to leach into the water. Plus‚ the water that is left in these mugs will stay fresh for a long-time and won’t start to taste stale. Here are five reasons to drink from a copper mug: Digestive system Copper contains beneficial properties that can promote the more efficient digestive system. A well-balanced diet that includes the copper-infused water

Introduction This lab proposed the question of what happens when copper chloride and iron are combined and what is the balanced equation.By completing this lab‚ the goal was to determine the equation and product for the reaction of iron (Fe) and copper chloride (CuCl2). It was predicted either solid iron or solid copper would form. Methods To begin‚ 6.00026 grams of copper chloride was dissolved in 50ml of distilled water in order to have a solution with charged iron and chlorine atoms. Then‚ 6

may affected the mass of the copper was recovered and also the percentage of yield. According to the law of conservation of matter‚ the mass of the copper will not change even though there are many chemical reactions happened which also mean that the mass of copper contained in solutions or precipitates remain the same as the copper in the beginning. And it is necessary to synthesize the various copper compounds in order to recover metal because the amount of copper might be left due to some errors

molecular formula of Copper Oxide through synthesis of copper oxide. In the first procedure‚ an empty crucible‚ Bunsen Burner‚ and electronic scale were placed onto the workbench. The electronic scale was zeroed before the crucible was placed on it. The total mass of the empty crucible was 88.000g. Afterwards‚ 10 grams of copper powder was placed into the crucible and weighed to be 98.000 g. The crucible with the copper was placed onto the Bunsen Burner. The initial color of the copper was red.
