A Lot of Copper Is Used in Building Construction

Copper is one of the oldest known metals, with evidence of its use dating back over 10,000 years. It was first discovered in the Middle East, along with other metals such as gold and silver. In fact, copper was likely the earliest metal that humans learned to work with. Over time, copper became an important material for many civilizations. The Ancient Egyptians used it for everything from tools to decorative objects, while the Greeks and Romans used it for coins, jewelry, and military equipment. In more recent history, copper has been used extensively in electrical wiring and plumbing. One of the reasons copper is so useful is because it is easily alloyed with other metals to create materials with desirable properties. Brass, for example, is an alloy of copper and zinc that is corrosion-resistant and has a golden color. Bronze, an alloy of copper and tin, is both strong and malleable, making it ideal for sculpture and other artistic applications. Copper alloys have played important roles in many pivotal moments in human history. The Bronze Age, for example, saw the widespread use of bronze tools and weapons throughout the world. Copper alloys were also crucial to the Industrial Revolution, as they were used in everything from steam engines to telegraph wires. Today, copper and its alloys continue to be used in a wide range of applications, including electronics, roofing, and medical equipment. Despite its long history, copper remains an important material that is constantly being improved and refined. New alloys are being developed all the time for specific applications, and copper itself is being used in innovative ways that were once impossible. As such, copper and copper alloys will likely continue to be important materials for centuries to come copper refinery copper scrap dealer

Copper sulfate is a common inorganic compound that is widely used in various applications such as agriculture, electroplating, and as a fungicide. While copper and acid can indeed react, the reaction between copper and acid does not result in the formation of copper sulfate. In order to form copper sulfate, copper needs to react with sulfuric acid. However, the reaction between copper and sulfuric acid is not straightforward. Instead of forming copper sulfate directly, copper first reacts with sulfuric acid to produce hydrogen gas and copper sulfate pentahydrate. The chemical equation for this reaction is: Cu + H2SO4 в†’ CuSO4.5H2O + H2. The copper sulfate pentahydrate produced in this reaction is a blue-green solid compound that contains water molecules. It can be further heated to remove the water molecules and obtain anhydrous copper sulfate, which is a white crystalline solid. Therefore, while copper and acid can react, it is not a suitable method for producing copper sulfate. Instead, copper and sulfuric acid need to be used in specific proportions and under controlled conditions to form copper sulfate pentahydrate, which can be further processed to obtain the desired form of the compound

Of course most of us can remember how, in 1943, our pennies were made of stainless steel (actually zinc-plated stainless steel) because demand for copper soared whenever a major war is on.

Nickel is also a critical war material - leading to nickels having been made of 56% copper, 35% silver, and 9% manganese from 1942 through 1945 instead of the customary 75% and 25% nickel.

By now one must be a coin collector to have knowledge of steel pennies. People hated them, and by 1944 the US mints were beginning to process spent shell casings into new copper cents. America needed lots of pennies for the civilian commerce of the time -- almost all of it was by cash or currency, and even with rationing there was much of it. Personal checks were for rich people by the standards of the time.

Despite inflation, America is printing no currency bigger than the $100 note. Cash transactions are becoming rarer at retailers because of ATM/debit cards well favored because they typically have direct deposit attached. Personal checks are almost entirely for mail transactions (you charged the bill or signed for the mortgage, or it is for a utility or taxes) or unusually-large transactions (as in real estate). The paycheck that one cashes on Friday for spending on Saturday is becoming an anachronism. SNAP comes on cards like this:



No currency ever needs change hands.

Tolling authorities are establishing non-cash tolling by what I call "electronic pick-pocket" in which people are obliged to put money onto a non-interest-bearing prepayment account for use when one drives through an array of transponders. Supposedly the collisions get reduced at toll booths, but it is a clever way for tolling authorities (especially entities deputized to collect the tolls) to get interest-free use of money and be able to raise tolls whenever desired.  

Of course, much of the US currency in circulation is in a way toxic: it's drug money. My position on drugs is obvious enough about the blood money that buys the drugs for addicts and weapons for drug lords for civil wars against anyone not under their thumb. It would be best if that toxic money vanished.
