Knowing Your Audience ans Communication Release The news of a devastating accident is not easy to prepare or communicate to any one involved. Being the bearer of bad news is never easy. The way in which the news is delivered‚ and what must be done before and after the news is relayed is also important. The needs of the employees is different than the needs of the family members of those men who were trapped in the mine. It is vital to make sure to address each of these groups in a

Introduction When iron is mixed to Copper (Ⅱ) Chloride; the product will be copper and iron chloride. However‚ in this experiment‚ we do not have the information of the oxidation number for iron nails. There are 2 different oxidation numbers for iron; that are 2 or 3. We will need to check each of the equations to find out the moles of each element in the equation. Then we can compare the ratio between the mole and the mass of iron and copper; that will be measured during the experiment. Finally

Here the production growth reflects the worldwide demand for copper‚ then very quickly increases tend to stabilize the. In the 1970s‚ the mining companies were iron production nationalized peaked at more than 750‚000 tonnes per year achieved. Such a level should be achieved never again in the 1970s a decade that

Determining the Percent Copper and Zinc in Pennies from Density Lab Report Procedure: For pre-1982 pennies- Mass 10 pennies‚ record data. Fill a 100mL graduated cylinder to 40mL or enough to fully submerge the pennies with water‚ record the volume in data table. Carefully place the pennies into the graduated cylinder‚ record the final volume of the water in data table. To find the volume of the pennies‚ subtract the final volume from the initial‚ record the data. Repeat this procedure twice more

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
