Copper sulphate

In 1991 two German hikers found a body stuck in the ice of Italian mountains. When the body was first found they thought that he was just another victim of a hiking accident. After further investigation, they concluded that he wasn’t just another body, but in fact a 5,300 year old mummy. The mummy was named Ötzi after the Ötztal Alps where he was found. Although scientists know how he was killed, they are still speculating why he was murdered. Scientists do know that he was killed by a 24 inch arrow

For our copper and sulfur experiment we used a crucible to hold the chemicals while they were heated. We also used a ring stand ring and a triangle to hold our crucible above the fire. A clay triangle was employed to hold the crucible above the bunsen burner’s flame. To take the hot crucible off of the clay triangle crucible tongs were utilized. Procedure A.) A Reaction Between the Elements Copper and Sulfur A 2 inch copper wire was obtained. The first observation of just the copper wire was

Iron has been here since the ancient Greece time no one knows who discovered this element. In fact, we still use this element to make structures steel, weapons, vehicles, anything that made of steel or iron. In Mesopotamia, there are evidence people that were smelting iron around 5000 BC. Artifacts made of smelted iron have been found dating from about 3000 BC in Egypt and Mesopotamia. In those times, iron was a ceremonial metal; it was too expensive to be used in everyday life. Iron has isotopes

During this experiment, one penny stayed almost the same, while the other one turned green and completely changed. The experiments started with two cups. One was labeled water, while the other one was labeled vinegar. In each cup, paper towels were placed at the bottom. In the cup labeled vinegar, vinegar was added and in the cup labeled water, water was added. Then, one penny was placed in each cup and observed on a span of four days. On the first day, penny A (cup with water) looked the same. Penny

INTRO: This is the examination and comparison of Otzi the Iceman and Narrabeen Man; ill be talking about where they were discovered, When they died, How they died, what was there life like, How they were preserved, The archaeological evidence that was discovered, interpretations from experts and the return of the remains to indigenous communities. QUESTIONS: Otzi the iceman was found in the Otzal alps on the Austrian–Italian border (that how he got his name Otzi) While Narrabeen man as found near

Issy 20/8/15 Where was Otzi the Iceman discovered? Otzi the iceman was discovered in Italy, his 5,300 year-old corpses were found between the border of Austria and Italy. The Narrabeen man was found in 2005 in the Sydney basin next to a bus stop. When did otzi the iceman die? Otzi the iceman died in 1991 in the border of Austria and Italy. The Narrabeen man died 5,300 years ago north of Sydney next to a bus stop. How did otzi the iceman die? Otzi the iceman died by Exsanguination, a

: During each reaction, something happened. During reaction 1, after adding the nitric acid a red-brown gas was created. The copper first turned green after a few minutes turned into a blue solution. Reaction 2, When acid was added a blue precipitate formed. Reaction 3, when heated the solution turned into a black precipitate. I noticed that the darker particles were denser than water. Dark particles began to settle to the bottom. Reaction 4, Sulfuric acid dissolved the black precipitate back to

Percent Copper and Zinc in Pennies From Density Purpose: Practicing determine the density of the solution. Developing the method for determine the percent of density for the solution. Examining the linear relationship by learning to use the best-fit straight line. Using the linear relationship to determine the percent of density by the solution. Be familiar with recording data and observations. Methods & Material: Methods: Weight the mass for the different percent of zinc and copper mixtures

up when it comes to mining the copper and nickel in the boundary waters. Sulfide mining has been stereotyped as a major pollutant to nearby waterways. As this may have been proven true with other mining corporations, PolyMet Mining has found a new way of reusing the sulfide as renewable energy instead of flushing it back into the waterways. Minnesota is home to one of the largest deposits of copper, nickel, and other precious metals. Currently there is only one copper and nickel mine currently being

4. Describe the procedure for extracting copper from one of its ores. Include relevant chemical reactions, equations and energy considerations involved. Extraction of copper from chalcopyrite (CuFe2) occurs using processes such as: mining & crushing, froth flotation, roasting & smelting and electrolytic refining. Mining the ore Copper ore contains approximately 0.5% copper and 99.5% unwanted rock. To help separate the mineral copper from the gangue (sand, rock and other impurities), the ore
