No, copper money is not magnetic. Copper is not a magnetic material, so coins made of copper or copper alloys like bronze are not attracted to magnets. This is why coins made of copper are often used in vending machines and coin-operated devices, as they will not interfere with the magnetic mechanisms used to detect and process the coins. **

Copper is lighter than copper oxide. This is because copper oxide is a compound formed by the combination of copper and oxygen, which increases its overall mass compared to pure copper. Therefore, in terms of weight, copper is lighter than copper oxide. **

Yes, one can make good money with copper as it is a valuable metal that is in high demand for various industries. Copper can be collected from a variety of sources such as old electronics, wiring, plumbing fixtures, and even scrap metal yards. Additionally, recycling centers often accept copper and pay for it based on its weight and current market value. By collecting and selling copper from these sources, one can potentially earn a decent amount of money. **

The chemical formula for copper oxide is CuO, for copper it is Cu, and for carbon dioxide it is CO2. Copper oxide is a compound formed by the combination of copper and oxygen, while copper is an element on its own. Carbon dioxide is a compound formed by the combination of carbon and oxygen. **

To produce copper from copper oxide, you can use a process called reduction. This involves heating the copper oxide with a reducing agent such as carbon (in the form of charcoal or coke) in a furnace. The carbon will react with the oxygen in the copper oxide, leaving behind the pure copper metal. This process is known as smelting and has been used for centuries to extract copper from its ores. Once the copper metal is obtained, it can be further purified and shaped into the desired form. **

Ötzi, the ancient iceman, likely extracted copper from copper ore using a technique called smelting. This process involves heating the copper ore in a furnace at high temperatures to separate the copper from the surrounding rock and other impurities. Ötzi may have used a combination of charcoal and blowpipes to create the necessary heat for smelting. Once the copper was extracted, it could be shaped and used for making tools and weapons. This demonstrates Ötzi's advanced knowledge of metallurgy and his ability to work with metal during the Copper Age. **

One way to get more money for copper is to research and compare prices from different scrap metal buyers or recycling centers in your area. Look for those that offer the best rates for copper. Another option is to clean and sort your copper before selling it, as clean and pure copper typically fetches a higher price. Additionally, consider holding onto your copper until the market price increases, allowing you to sell it for a better return. **

No, copper sulfide is not a mixture of copper and sulfur. It is a chemical compound composed of copper and sulfur atoms chemically bonded together in a specific ratio. In copper sulfide, the copper and sulfur atoms are bonded together in a fixed proportion, forming a distinct chemical compound with its own unique properties. Therefore, it is not a mixture but a compound. **
