Initial chemical formula is: CuSO4.5H2O.

Dehydration:

- CuSO4.3H2O at 63 0C

- CuSO4.H2O at 109 0C

- CuSO4 at 200 0C

Thermal decomposition after 650 0C:

CuSO4 = CuO + SO3

Where does copper come from'?

Copper is primarily obtained from sulfide minerals such as chalcopyrite or bornite, which are typically found in copper ores. These ores are mined and processed to extract the copper metal through a series of steps including crushing, grinding, and smelting. Copper can also be recovered from recycled materials such as scrap metal or electronic waste.


How is copper refined and what are the key steps involved in the refining process?

Copper is refined through a process called electrolysis, which involves passing an electric current through a solution of copper sulfate. The key steps in the refining process include crushing and grinding the ore, smelting to remove impurities, converting the copper matte into blister copper, and finally electrolysis to produce pure copper cathodes.


How do you make copper oxide from copper carbonate?

Carbonate Decomposition Aim: To investigate the decomposition of a carbonate. Equipment: · Copper Carbonate (CuCO3) · Limewater · Bunsen Burner · Matches · Test tubes · Clamp and stand · Hydrochloric Acid · Electronic Scales Method: 1. Weighed Copper Carbonate by taring empty test tube. 2. Placed some Copper Carbonate in a test tube fitted with gas delivery tube and stopper. 3. Clamped the test tube to the stand at a slight angle. 4. Half filled another test tube with limewater and placed the other end of gas delivery tube into it. 5. Using a small blue flame gently heated the carbonate. Observed what happened. 6. Removed gas tube from limewater before turning off the Bunsen burner. 7. Allowed to cool 8. Weighed the remaining Copper Carbonate. 9. Added approximately 5ml of Hydrochloric Acid to the solid residue (Copper Oxide) from the decomposition reaction. 10. Transferred a small amount of original Copper Carbonate to new test tube and added same amount of Hydrochloric Acid to that. Recorded observations. Results: Observations from Decomposition: The limewater turned milky. Observations from HCl & Copper Oxide: Small bubbles. Hardly a reaction. Observations from HCl & Copper Carbonate: Bubbles & fizzing. Small amount of heat generated. Turned milky green in colour. Reacted immeadiately. Conclusion: The limewater proved that Carbon Dioxide was produced as a result of thedecomposition reaction. The Copper Oxide test showed that theoretically there should be no reaction with HCl. Copper Carbonate, however, theoretically, should react. Evaluation: Overall, the experiment was a success except for the fact that the HCl shouldn'thave reacted with the Copper Oxide but did. This is probably due to the fact there was some Copper Carbonate still stuck to the side of the test tube and the HCl reacted with that.


How many copper atoms are in a pure copper statue with a mass of 148kg?

To find the number of copper atoms in the statue, you need to first determine the number of moles of copper using its molar mass. Then, you can multiply the number of moles by Avogadro's number to find the number of atoms. Given that the molar mass of copper is approximately 63.55 g/mol, you can follow these steps to calculate the number of copper atoms in the statue.


What is the chemical name of the product when copper reacts with gas in the air?

Copper reacts with the oxygen in the air in a process called oxidation. This occurs in several steps as seen in Kuba Jasinski’s answer. The reactions occur as the copper atoms give up some electrons (oxidation) to the oxygens (reduction) to create ionic compounds. This is a classic example of what is called a redox (reduction-oxidation) reaction.

How do you get copper metal from copper ore?

It depends upon nature of ore the most common ore of copper is Copper pyrite CuFeS2. the extraction of copper from this ore involves the following steps, 1-crushing, 2-grinding, 3-concentration of ore, 4-roastiong, 5-smelting, 6- preparation of blister copper and 7- electrorefining of blister copper.


What are the steps for properly installing a compression fitting on a copper pipe?

To properly install a compression fitting on a copper pipe, follow these steps: Cut the copper pipe to the desired length using a pipe cutter. Slide the compression nut and compression ring onto the pipe. Insert the pipe into the fitting until it reaches the bottom. Tighten the compression nut onto the fitting with a wrench until it is secure. Check for any leaks by turning on the water supply. Following these steps will ensure a proper installation of a compression fitting on a copper pipe.

How is copper processed in the mining industry?

Copper is processed in the mining industry through a series of steps. First, the ore containing copper is extracted from the ground. Then, the ore is crushed and ground into fine particles. Next, the copper is separated from the ore using a process called flotation. Finally, the copper is purified and refined to remove impurities and produce high-quality copper products.
