How do you separate copper from copper oxide?
I think you mean how do you extract copper from copper oxide, if so here's your answer. Take your copper oxide and heat it with something that is more reactive than copper. Carbon is a good example. The more reactive carbon will oxidise, taking the oxygen from the copper oxide leaving copper. copper oxide + carbon --> copper + carbon dioxide 2Cu0 + C --> 2Cu + CO2
How can you separate iodine mixed with zinc oxide?
One way to separate iodine from zinc oxide is through sublimation. Since iodine sublimes at a lower temperature than zinc oxide, you can heat the mixture to a temperature where iodine sublimes, and then collect the iodine vapors while leaving behind the zinc oxide.
Why does zinc plus copper oxide equal copper plus zinc oxide?
This is a chemical reaction known as a displacement reaction. Zinc has a higher reactivity than copper, so when zinc is added to copper oxide, it displaces copper from the compound forming zinc oxide and copper metal. This reaction occurs because metals higher in the reactivity series can displace metals lower in the series from their compounds.
How could separate zinc chloride from silicon oxide?
Zinc chloride is very soluble in water and silicon dioxide is not soluble. - Put the mixture of ZnCl2 and SiO2 in water - Wait for the dissolving of the ZnCl2 - Separate the two components by filtering
Is brass an element compound or mixture?
Brass is a mixture of copper and zinc. It is not an element on its own.

How do you separate iodine and zinc oxide?
Iodine and zinc oxide can be separated using a process called sublimation. This involves heating the mixture, causing the iodine to change from a solid to a gas and leaving behind the zinc oxide as a solid residue. The iodine gas can then be collected and condensed back into a solid form.

Brass is a mixture of copper and zinc. It is not an element on its own.
Is zinc oxide a mixture?
No. It is a compound.
How many elements does a mixture of iron copper and zinc contain?
A mixture of iron, copper, and zinc contains three elements: iron, copper, and zinc.
Why copper rods not used to separate zinc from zinc sulphate?
Copper rods cannot separate zinc from zinc sulphate because copper is less reactive than zinc, and cannot separate the zinc which is more reactive than copper. If you get copper sulphate and add some zinc to it, you will see solid copper appearing on the bottom of the test tube... The copper cannot push out the zinc from the solution and take its place.
Is brass a mixture or pure substance?
Brass is considered a mixture because it is composed of two or more elements (copper and zinc) that are physically combined but can be separated through physical means.
What do you call a mixture of copper and zinc?
A mixture of copper and zinc is called brass. Brass is an alloy composed of varying ratios of copper and zinc, which results in a material that is resistant to corrosion and has a desirable gold-like appearance.
Why does zinc separate copper sulphate?
Because zinc is more reactive than copper.
