How much is a misprinted 2002 mississippi state silver proof quarter with the p mint mark on it worth?
The coin is unlikely to be silver because the only silver State quarters were minted* in San Francisco and sold in special Prestige proof sets. If the coin doesn't display a copper edge it should be examined in person by a numismatic expert, but my guess is that it will turn out to be a plated copper-nickel coin rather than an actual silver quarter. (*) To set things straight, coins are said to be "minted" or "struck". Printing refers to paper and ink.
What are four metals found in free state?
gold, silver, copper, platinum and some other platinum metals
What substance is formed on the surface of copper metal when it is placed in a solution of silver nitrate?
When copper metal is placed in a solution of silver nitrate, a reddish-brown solid called copper(I) oxide is formed on the surface of the copper. This occurs due to a single displacement reaction where copper displaces silver from the silver nitrate solution.
Which US state is nicknamed The Copper State?
The great US state of Arizona accounts for two-thirds of the nation's copper output. Gold, silver, and molybdenum are produced as byproducts of copper mining in Arizona.
What is the product grown in the state of Arizona?
Copper, Zinc, Gold, and silver are grown in the state of Arizona
When copper reacts with silver nitrate what element is set free?
If the silver nitrate is in aqueous solution and the copper is solid in contact with the solution of silver nitrate, copper atoms will dissolve as ions from the surface of the copper and be replaced by silver atoms formed from the silver ions in solution. This reaction will continue until the entire surface of the copper in contact with the solution is covered with silver. The chemical driving force for this reaction is displacement of one element from its compounds by another element that is higher in the electromotive series than the element displaced.
What state is silver in when naturally found?
Silver is typically found in nature in its ore form, primarily as silver sulfide (argentite) or as part of other minerals like galena (lead sulfide) and copper ores. It can also be found in native form as small nuggets or grains. In its natural state, silver is usually mixed with other metals and minerals rather than existing as pure silver.
Electroplating of copper can be made on iron but not in silver why?
Electroplating of copper on iron is feasible because iron is more reactive and can readily accept copper ions in a suitable electrolyte, allowing for a strong bond between the metals. In contrast, silver is less reactive than copper, creating challenges for the deposition process, as copper may not easily displace silver ions from their metallic state. This results in poor adhesion and a lack of effective electroplating when attempting to deposit copper on silver.
Examples of native minerals?
Some examples of native minerals include gold, silver, copper, diamond, and graphite. These minerals are naturally occurring and are composed of a single element, making them distinct from other types of minerals. They are typically found in their pure form, without being chemically combined with other elements.
Which metals occurs in a free state?
Only a few metals are found in the free state, generally metals react to form for example oxides, sulfides which then may further react. Some found free are gold silver copper and platinum. All of these are relatively unreactive
What the examples of solid solution?
Examples of solid solutions include sterling silver (silver and copper), brass (copper and zinc), and steel (iron and carbon). These solid solutions form when components are dissolved into each other at the atomic level in a solid state.
How do you define atomic state?
Some elements that are not chemically combined with any other substance exist as single atoms. Pure copper, pure lead, pure silver. Oxygen does not, the pure state of oxygen is a diatomic molecule, O2.
