Affecting the Copper Mining Industry As is demonstrated by the chart below‚ the demand for copper has exceeded the supply brought to market since 2009. In 2011‚ 16.5 million tonnes of copper were produced worldwide and this amount is expected to grow by approximately 3% annually. Data from the International Copper Study Group (ICSG) for 2012 suggests that international demand for refined copper is expected to exceed production by about 240‚000 metric tons. The slow growth forecasted in copper supply is

Reactions of Copper Data: Part I: Preparing a solution of copper (II) nitrate Initial mass of copper wire: .520g Mass of copper wire after vigorously scouring: .518g Observations of Copper (II) ribbon mixed with HNO3: Solution turned green. Thick brown gas formed. Copper (II) bubbled vigorously. Cu (II) dissolved‚ solution appeared green/blue. After the addition of H2O a blue crusty precipitate formed. Part II: Synthesis of solid copper (II) hydroxide Observations of Copper (II) nitrate

Percentage of Copper in a Brass Alloy Assignment: G620 Sample Assignment C Date Set: Due Date: Assessment Objective(s): AO3 Vocational Brief: Brass is an alloy of copper and zinc. This alloy has many uses ranging from coinage to non-ferrous fittings on ships. Many domestic taps use brass where contact with water occurs. You are provided with a sample of brass which is about 150 years old and you are asked to quantitatively analyse it‚ using colorimetry‚ to find the percentage of copper present

In order to find the formula of the copper chloride hydrate‚ we had to separate the compound to find the mass of water and copper. To begin this process‚ we evaporated the water and created an anhydrous compound‚ meaning we were left with only CuxCly. By calculating the weight of both the anhydrous and the hydrated compounds‚ we could conclude that the difference in the weights was the weight of the H2O. From this we were able to calculate the percent composition of CuxCly and H2O (see Calculations:

3.4 Part F – The Reaction of Iron Nails with a Copper Solution Introduction: The experiment in this activity involves the reaction between a copper (II) chloride solution with iron nails and the mole ratios involved in the reaction. Measurements are taken to determine the moles of each reactant involved in the reaction and thus the number of atoms or molecules involved. Apparatus and Materials: Refer to the reaction of iron nails with a copper solution assignment in Module 3‚ Section assignment

Copper vs. fiber Everyone building a network must face this question at some point: fiber or copper wiring? For a usual home network or even a big office either one will suffice but what is the best option for you or your company. You have to take cost‚ distance of cabling‚ and bandwidth and speed into consideration when making this choice. Copper: a traditional copper wiring for a network certainly seems much cheaper on the surface. Copper wiring itself is dirt cheap at least comparatively

and Processing Raw data Table of raw data Qualitative observation: At the start of the experiment‚ the crystals were blue. During the heating‚ the crystals turned white which means that they lost their water molecules. The source of hydrated copper sulphate consists of both small grains and large grains of the salt. Therefore during the heating process‚ the smaller grains of the hydrated salt turned from blue to white in just 1 minute. In other words‚ there is an uneven heat distribution‚ which

The Society depends on the annual fund raiser to maintain the shelters‚ provide food and medical care for the orphaned cats and dogs in our community. The Society relies on local businesses‚ individuals‚ and students to solicit donations and promote the annual campaign. This year’s fund raiser was a huge success.
