Name one metal that is purified on a large scale by electrolysis?
Aluminum is one metal that is purified on a large scale by electrolysis. It involves passing an electric current through a molten mixture of aluminum oxide and cryolite to extract pure aluminum metal.
Is aluminium oxide mixture element or compound?
Yes. Aluminum nitrate is a compound with the formula Al(NO3)3
Why cant carbon push aluminium out of aluminium oxide?
Carbon cannot push aluminum out of aluminum oxide (Al₂O₃) because the reduction of aluminum oxide to aluminum requires a more reactive element than aluminum, and carbon is not reactive enough for this purpose under normal conditions. The thermodynamic stability of aluminum oxide means that carbon would need to achieve a significantly higher temperature to reduce it. Additionally, in typical extraction processes like the Hall-Héroult process, aluminum is produced using electrolysis rather than direct reduction with carbon.
Is an aluminum can a compound element heterogeneous or homogeneous mixture?
Aluminum cans are made almost entirely of aluminum. The interiors are made of aluminum oxide, which is highly resistant to corrosion. This is a compound, not a mixture.
Why carbon is used to extract lead from lead oxide?
Carbon is used to extract lead from lead oxide because it acts as a reducing agent in the smelting process. When carbon is heated with lead oxide (PbO), it reacts to form carbon dioxide (CO2) and lead (Pb), effectively reducing the lead oxide to elemental lead. This process is thermodynamically favorable and economically viable, making carbon a practical choice for extracting lead in metallurgical operations.
A metal whose oxide is reduced only by carbon?
Aluminum is a metal whose oxide is reduced only by carbon. When aluminum oxide is reduced by carbon, it forms aluminum and carbon dioxide.
Is aluminum oxide a mixture?
No, aluminum oxide is a compound composed of aluminum and oxygen atoms bonded together in a fixed ratio. It is a chemical compound, not a mixture.
What do you get when you mix aluminum oxide and iron oxide?
It will form a mixture of the two compounds.
Name one metal that is purified on a large scale by electrolysis?
Aluminum is one metal that is purified on a large scale by electrolysis. It involves passing an electric current through a molten mixture of aluminum oxide and cryolite to extract pure aluminum metal.
Why is carbon not used for reducing aluminum from aluminum oxide?
Carbon cannot be used for reducing aluminum from aluminum oxide because aluminum is more reactive than carbon. This means that aluminum is not easily displaced by carbon in the reduction reaction. Instead, aluminum is typically extracted from its ore using electrolysis.
Is aluminium oxide mixture element or compound?
Yes. Aluminum nitrate is a compound with the formula Al(NO3)3

Is carbon Di oxide flammable mixture?
no
How do you extract aluminum from aluminum oxide?
You need to pass an electric current throguh the molten aluminum oxide which is the ore for alumium and then u get pure aluminum at the bottom because its denser than aluminum oxide. Carbon dioxide is produced as well because the metals used to pass the electric current are carbon and the ocsigen reacts with the carbon to create carbon dioxide.
Why does heating with carbon extract copper from copper oxide?
Heating copper oxide with carbon (in the form of coal or charcoal) causes a reduction reaction, where carbon removes oxygen from copper oxide to produce carbon dioxide and leave behind pure copper. This process is known as a reduction reaction, where carbon acts as a reducing agent to extract copper from its oxide form.
Why can't aluminium be extracted from aluminium ore using a blast furnace?
Because it is more reactive then carbon to be extracted in a blast furnace. Remember carbon is the reducing agent and for it to work the metal being extracted has to be lower in the reactivity series, e.g. iron
