Copper: The Most Electrically Conductive Metal Element

The main goal of this experiment was to observe series of reactions that convert a piece of copper metal, via several different copper-containing compounds, back into its original elemental form. The data collected was the striking color changes along with their relevant chemical equations. The data was collected while keeping a close eye on the experiment the whole time. The data recorded was used to see the different changes involved with a piece of copper metal. The copper was weighed and heated multiple times throughout the experiment

When mining gold there is about 1 ounce of gold per ton though when mining on the surface that statistic drops to about 0.5 ounce of gold per ton. Gold is highly valued at about $120,000 per truck this is because gold is malleable, and it never loses luster or rusts. Next, copper which is also a valued metal because of its specific properties, it conducts electricity and bacteria doesn’t like to come in contact with copper. Many people have found the value in copper and trade copper in the same way stocks and shares of companies are traded. And finally bronze which is made of 80% copper and 20% tin, bronze is used in the manufacturing of bells. Bronze is used in the making of bells because when copper, a pure substance, is hit it creates a ripple effect making the bell easy to dent, with tin the rows of copper atoms are more stabilized, but too much tin can result in a bell cracking as the Liberty bell did.

As for metal, it has many uses. In fact, modern civilization has thrived off of things where iron is used like: buildings, car frames, bridges, and much more.

The purpose of this lab was to determine the empirical formula of copper oxide compound. In the lab, hydrochloric acid and copper oxide compound was mixed until it formed a blue solution. An oxidation-reduction reaction, a reaction in which there is an exchange of electrons between elements, was performed by adding zinc to the solution to displace the copper in copper chloride. Zinc, in this case, was oxidized by losing two electrons (0 → 2+) while copper was reduced by gaining two electrons (2+ → 0). Also, when the copper was displaced, it became a precipitate, which is a substance that comes out of a solution as a solid due to insolubility.

The purpose of the experiment is to cycle solid copper through a series of five reactions. At different stages of the cycle, copper was present in different forms. First reaction involves reaction between the copper and nitric acid, and copper changed from elemental state to an aqueous. The second reaction converted the aqueous Cu2+ into the solid copper (2) hydroxide. In the third reaction Cu(OH)2 decomposed into copper 2 oxide and water when heated. When solid CuO reacted with sulfuric acid, the copper returned to solution as an ion (Cu2+). The cycle of reactions was completed with the reaction where elemental copper was regenerated by Zn and Cu

The purpose of performing the variety of tests that we did was to give more accurate results of what the unknown mineral was. By roasting the copper mineral, we obtained copper(II) oxide. This new sample came out of the crucible grayish-black. It was very brittle and full of cracks. This provided the percent composition that was necessary in finding the unknown mineral. When performing

For our science assessment we had the task to research about a metal of our choice. Since I am really into computers, I chose copper. A metal used in all kinds of wires, cpu’s and other stuff without a computer wouldn’t work. This fits really well into what we have to do for the second part, describe how this metal has helped human society.

Introduction: The purpose of this lab was to learn the proper techniques of roasting, smelting, and volumetric analysis to determine an unknown sample of copper mineral.

Did you know the Statue of Liberty is made of copper? The Statue of Liberty is not originally green, it was a dull brown colour but turned green from many years of oxidation.Copper (Cu), Copper’s atomic number is 29 and has the atomic weight of 63.546.Copper is a mineral and an element essential to our everyday lives. It is a major industrial metal because of its high ductility, malleability, thermal, electrical conductivity and resistance to corrosion. It is an essential nutrient in our daily diet. And, its antimicrobial property is becoming increasingly important to the prevention of infection. It ranks third after iron and aluminum in terms of quantities consumed in the USA.Copper has the melting point of 1,981° F (1,083° C) and a boiling

Copper is extracted from chalcopyrite ore, its chemical formula is CuFeS2. Chalcopyrite is a brass-yellow mineral with a chemical composition of CuFeS2. Most sulfide mineral deposits in Australia contain chalcopyrite ore and has been the most valued ore of copper for thousands of years.

During lab, we put the metal copper under different circumstances so that we could gain a better understanding as to what goes on in the copper cycle. Throughout each stage of the copper cycle, we deduced what type of chemical reaction took place based on observation, made observations about the state of the metal and what type of environment it was subjected to, and determined what the net ionic equation was for each stage. Following the experiment, we calculated what the percent yield was and compared the changes in mass from the initial stage to the final stage.

Copper has a very important biological and environmental significance, and is considered one of the most important elements all over the world. Within this experiment, copper’s ionic and elemental forms will be examined. This will be done by exposing copper to a series of chemicals and transforming copper into a nitrate, a hydroxide, an oxide, a sulfate, and then changing it back to its original element, copper. This process is known as the Copper Cycle, and can be used to study and observe the different types of chemical reactions that exist within our biological and environmental systems.

Copper, dating back almost 10,000 years, is the first metal to ever be used by man. It was thought that copper could replace stone on weapons and tools during prehistoric times, but was then discovered that the malleable metal, was too soft to be used for such purposes, so instead was used in pottery in North Africa. Leading to the Bronze Age, 5,000 years ago, people learned that, if mixed with other metal alloys such as bronze or brass, copper could be strengthened. For centuries onward, these alloys were used to make tools, weapons, and armour until 1200 B.C when the Bronze Age ended. During the invention of the telephone in the 1870’s, the need for copper grew as large quantities of copper wire for the electric power grid were being utilized.

Early uses of the element include jewelry, weapons, and tools. The element was first used around 9000 b.c.e. and was found in northern Iraq. Copper was first used by Native Americans around 2500 b.c.e. One of the first skills that the ancient coppersmith must have learned how to do was shape the metal, possibly by heating. This element was first used to its full potential when Coppersmiths began to use tin with copper to make an alloy called bronze. An alloy is a mixture of two or more metals with properties differs from those of the individual metal. The alloy was first discovered as early as 4000 b.c.e. Bronze was used similar to copper due to the many variety of tools, weapons, and jewelry that are created from the alloy. It differs from copper in the way that with tin added, the alloy is a better conductor and easier to shape than the metal alone. Copper was used as the primary metal of the world to around 3000 b.c.e when society discovered iron. Many copper compounds are used in today’s agricultural, medical, and pest-control jobs. Copper Acetate (Cu20 (C2H3O2) 2) is a
