What else can I help you with?
What is the element that is a white solid with a melting point of 730 degrees Celsius and when electricity is passed through the resultant liquid a brown gas and molten metal are produced?
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.
Is molten iron a heterogeneous mixture?
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.
What is the symbol for molten iron?
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 this element using a battery?
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.
What type of compounds can be electrolysed?
Ionic compounds that are either molten or dissolved in a solvent can be electrolyzed. This allows the ions in the compound to move freely and conduct electricity. Covalent compounds are generally not electrolyzed because they do not dissociate into ions in solution.
Which element could be formed at the anode when a molten salt is electrolysed?
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.
When molten sodium chloride is electrolysed the product at cathode is?
sodium metal is deposited at the cathode.
How do scientists separate the sodium out of sodium chloride?
When a mixture of 42% NaCl and 58% CaCl2 is electrolysed in Down'cell pure molten sodium metal is obtained.
Why alumina is electrolysed in molten state?
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.
What rock is formed by molten material?
a molten rock
What Rocks formed by molten material?
a molten rock
What is produced when sodium chloride is electrolysed?
Electrolysis of molten sodium chloride: the products are sodium and chlorine. Electrolysis of sodium chloride solution: the products are hydrogen and chlorine.
Is molten copper a compound element or mixture?
Copper is an element.
What is the rock called that is formed from molten rock?
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?
Rocks formed from hot molten rock that has coold and hardened are called what?
What is the difference between molten and igneous rock?
Molten rock is still a liquid. Igneous rock is what is formed when molten rock solidifies.
How are rocks and minerals formed?
Rocks are formed from the solidification of molten magma, from the erosion and consolidation of eroded rock, or from the sedimentation of organic matter. Rocks are composed of minerals. Minerals are combinations of elements and are formed in response to many factors which include temperature, pressure, and element availability.
