Do compounds containing iron and copper look like the elements iron and copper?
no.
What is the product obtained by combining fehlings a and fehlings b solution?
When the two Fehling Solutions A and B are mixed, a deep blue solution containing a complex cupric ion is formed. On interaction with reducing compounds such as aldehydes or sugars, the copper is reduced to the univalent stage, and a red, yellow, or yellowish green precipitate is formed.
Which two compounds are in copper oxide?
copper and oxygen
Why do copper compounds usually appear colourless although copper is a transition element?
Sorry, but most copper compounds are some shade of blueor green, not colorless at all!
How much copper can be obtained from 100 gram of copper sulphate?
Exactly 33,13035046 grams of copper.
Copper can be obtained from solutions containing copper compounds by what?
By the the intermediate of chemical reactions; an example is the reaction of copper sulfate with iron (Fe is more reactive).
Do compounds containing iron and copper look like the elements iron and copper?
no.
Is copper chloride a pure substance?
Copper chlorides (CuCl and CuCl2) can be obtained as very pure compounds.
What is the product obtained by combining fehlings a and fehlings b solution?

What is bio-leaching?
Some bacteria absorb copper compounds. They then produce solutions called leachates, which contain copper compounds. This method of extraction is called bioleaching.
What is the word obtained after unscrambling the word eurazti?
The anagram is azurite, a blue mineral containing copper.
What is hydrometallurgy?
The use of aqueous solutions for the recovery of metals. Example: Leaching of copper oxide ores using a sulphuric acid solutions (or solution containing sulphuric acid). The Copper can then be recovered from solution using solvent extraction and electrowinning.
How is copper normally found in the ground?
In ores. Copper ores are found in various parts of the world. Copper can be found as a metal in the ground. Normally, it is green on the outside. Most copper is not as a metal but in chemical compounds. Chalcopyrite is the most common copper ore. It is a mixture of pyrite and copper sulfide. Copper is found in small amounts in living things. Some mollusks and arthropods have blue blood because they have copper in their blood. Animals such as humans and other mammals have red blood because it contains iron. Copper is purified by electrolysis. Electricity is passed through solutions containing copper compounds, such as copper sulfate - sometimes spelt sulphate. Pure copper forms on the negative electrode.
How can you be sure that the oxides of copper are different from compounds?
Oxides of copper are compounds !
What is the net ionic equation for copper 2 nitrate and barium chloride?
Copper nitrate and barium chloride do not react. Barium chloride solution produces a white precipitate with solutions containing sulfate ions.
Can copper sulphate used on cuts?
Copper sulphate obtained from the pharmacy can be used on cuts. Other sources of copper sulfate, such as root removing compounds cannot be used on the skin because they contain other substances. Copper sulphate can help to kill pathogens that cause infection.
Which is more stable zinc II compounds or copper II compounds?
copper II compounds are more stable because it is hard
