When molten aluminum oxide is electrolyzed, it forms aluminum metal at the cathode and oxygen gas at the anode. This process is used in the extraction of aluminum from bauxite ore.
The element described is sodium. Sodium is a white solid at room temperature with a melting point of 730 degrees Celsius. When electricity is passed through molten sodium, it produces a brown gas (chlorine) and molten metal.
No, molten iron is a pure substance because it is composed of only one type of element, which is iron. Unlike mixtures which contain two or more different substances mixed together, molten iron has a uniform composition.
Molten iron is the same element as solid iron, so the chemical symbol is Fe. Iron is not soluble in water, so you won;t find Fe(aq)
Davy discovered the element potassium by isolating it through the electrolysis of molten potassium hydroxide using a voltaic pile, a type of battery, in 1807.
Partially molten iron is considered a mixture because it consists of a combination of liquid iron and solid iron phases. This mixture contains variable compositions of iron and other elements, depending on the conditions of the material.
When a molten salt is electrolyzed, the element that could be formed at the anode is typically a halogen, such as chlorine or fluorine, depending on the composition of the salt. During the electrolysis process, anions migrate to the anode, where they are oxidized, releasing their electrons and forming gases. For example, in the electrolysis of sodium chloride (NaCl), chlorine gas (Cl₂) is produced at the anode.
sodium metal is deposited at the cathode.
When a mixture of 42% NaCl and 58% CaCl2 is electrolysed in Down'cell pure molten sodium metal is obtained.
In solid state, Aluminium and oxide ions are immobile. When aluminum oxide is melt down,aluminum and oxide ions become free and they can easily migrate to respecve electrodes. Therefore, aluminum oxide is electrolysed in molten state.

Copper is an element.
Electrolysis of molten sodium chloride: the products are sodium and chlorine. Electrolysis of sodium chloride solution: the products are hydrogen and chlorine.
The rock formed from molten rock is called igneous rock. It is formed when magma cools and solidifies either underground as intrusive rock or on the Earth's surface as extrusive rock.
Rocks formed from hot molten rock that has coold and hardened are called what?
Molten rock is still a liquid. Igneous rock is what is formed when molten rock solidifies.
When magma - molten rock - solidifies, it does form an igneous rock.
