How malachite rocks are Form?
Malachite rocks are formed through the weathering and oxidation of copper ores. The process involves the release of copper ions, which react with carbonate ions to form malachite crystals. These crystals accumulate over time to create malachite rock formations.
What rock did malachite?
The predominant metal in malachite is copper.Related Information:Malachite is an opaque bright blue to bright green copper carbonate hydrate, a semiprecious mineral, that contains the metal copper in combination with carbonate and hydroxide groups. Malachite often contains other metals, but only in small amounts.The chemical formula for malachite is CuCO3.Cu(OH)2.
Which metal occurs in native as well as combined form?
Most of the metals can occur in the native and combined forms.
Why does vinegar clean a penny?
Clean MoneyI read somewhere that copper pennies can be cleaned by soaking them in olive oil, but some collectors recommend not to clean coins. Another great way to clean pennies is to use a solution of vinegar and salt. Fill a cup about 1/4 of vinegar and a teaspoon of salt (more salt, faster reaction). The tarnish that forms on a penny is copper oxide. The salt and vinegar create an acid solution that causes the copper oxide to dissolve off the coins. Once they are clean they should have their original shiny coat. Remember though, if there are pits in the pennies they will show now that the oxide has been removed. If you don't have vinegar any acid such as lemon juice or Coke/Pepsi will work as well.HOWEVER ....Cleaning an ordinary modern penny is fine because there are so many of them. But you should NEVER, EVER try to clean a collectible coin because anything you have at home will damage the coin's surface and reduce or even destroy its value to another collector.If you clean pennies with just salt, it wouldn't be clean. If you cleaned them with just vinegar, it wouldn't be clean.
Is oil and vinegar an element compound heterogeneous mixture solution or colloid?
Oil and vinegar form a heterogeneous mixture.
What removes tarnish on pennies?
Vinegar, lemon juice, or a paste made of salt and vinegar can effectively remove tarnish on pennies. Simply soak the pennies in the solution for a few minutes, then gently rub them with a cloth or toothbrush to reveal the shiny surface.
What is created when a penny sits in a paper towel wrapped in vinegar?
Pennies get dull over time because the copper in the pennies slowly reacts with air to form copper oxide. Pure copper metal is bright and shiny, but the oxide is dull and greenish. When you place the pennies in the vinegar solution, the acetic acid from the vinegar dissolves the copper oxide, leaving behind shiny clean pennies.
What does vinegar do to pennies if submerged for three days?
There is acid called ACETIC ACID it combines with the copper to form a copper acetate(the green coating on the pennies)!!!!!!!!!!!!!!!!!! coiol huh

Do pennies rust in water vinegar and bleach?
A mixture of water, vinegar, and bleach is corrosive to most metals. If pennies are placed in it, the copper will oxidize. Rusting is a term only applying to the oxidization of iron, not other metals. The pennies will look a lot cleaner and the liquid will turn blue. If you leave the pennies in the mixture too long, holes may start to form in them.
Why do salt and vinegar patina penies?
Salt and vinegar create a patina on pennies primarily due to the acetic acid in vinegar and the sodium chloride in salt, which facilitate a chemical reaction. When pennies, primarily made of copper, are exposed to this mixture, it accelerates the oxidation process, resulting in the formation of copper salts and other compounds that give the pennies a greenish or tarnished appearance. This reaction is a form of corrosion that can enhance the aesthetic appeal of the coins for collectors or artists.
What is the transparency of malachite?
The transparency of malachite is opaque in massive form and translucent in crystalline forms.
What happens when copper pennies are soaked in vinegar?
The surface of the copper on the pennies are most likely cleaned, because vinegar is too weak of an acid to do anything else. If you were to put a scratched penny into hydrochloric acid would be a different story. The inside zinc of a post 1982 penny would react with the chlorine in the hydrochloric acid and change to an aqueous state, leaving behind the copper plating. So if you want an answer based on vinegar : nothing besides the penny getting its surface cleaned.
What is the word equation for the reaction that happens when malachite is heated?
The chemical equation is:Cu2CO3(H2O)----------------2 CuO + CO2 + H2O
