How is berryllium made?
Beryllium is primarily produced through the process of chemical reduction of beryllium fluoride with magnesium metal. This reaction produces beryllium metal and magnesium fluoride as byproduct. Another method of production is through the reduction of beryllium oxide with carbon in a high temperature furnace.
What type of chemical reaction is always involved in the extraction of metal from its ore?
The extraction of metal from its ore typically involves a reduction reaction, where the metal oxide in the ore is reduced to the elemental metal using a reducing agent such as carbon or hydrogen. This reduction reaction is necessary to separate the metal from the impurities in the ore.
What is removed when a ore is reduced by carbon?
When an ore is reduced by carbon, oxygen is typically removed from the ore. This process, known as reduction, involves the carbon reacting with the oxygen in the metal oxide, resulting in the formation of carbon dioxide or carbon monoxide, and leaving behind the pure metal. For example, in the reduction of iron oxide (Fe2O3) using carbon, iron is produced while carbon dioxide is released.
What kind of reaction is used in electroplating?
The principal reaction is the reduction of a metal cation; this metal is deposed on the "electrode".
What gas is produced when acid corrodes metal?
Hydrogen gas is typically produced when an acid corrodes metal. This reaction occurs when the acid reacts with the metal to form a metal salt and hydrogen gas as a byproduct.
What happens at the cathode in an electrolytic cell?
Reduction occurs at the cathode in an electrolytic cell.
What metal oxides can be converted to the metal by carbon reduction but not by hydrogen reduction?
any metals below carbon in the reactivity series. :)

Give mechanism for the reduction of NO2 to NH2.?
The reduction of NO2 to NH2 involves adding hydrogen gas in the presence of a metal catalyst such as platinum or palladium. The hydrogen gas reacts with the nitro group to form an intermediate compound, which then undergoes further reduction steps to yield the amino group. This process is commonly known as catalytic hydrogenation.
What type of chemical reaction is always involved in the extraction of metal from its ore?
The extraction of metal from its ore typically involves a reduction reaction, where the metal oxide in the ore is reduced to the elemental metal using a reducing agent such as carbon or hydrogen. This reduction reaction is necessary to separate the metal from the impurities in the ore.
Reduction is the gain of oxygen by a metal?
no, that is oxidation. Reduction is when the metal is reduced from its metal oxide to its elemental form. As turning rust into iron.
Where does reduction occur in an electrolytic?
Cathode
What is the mechanism involved in the reduction of nitrobenzene to aniline?
The reduction of nitrobenzene to aniline involves the addition of hydrogen gas in the presence of a catalyst, typically a metal like palladium or nickel. This process, known as catalytic hydrogenation, leads to the conversion of the nitro group (-NO2) in nitrobenzene to an amino group (-NH2) in aniline.
If you remove oxygen from a metal oxide what is the reaction type?
The removal of oxygen from a metal oxide is typically a reduction reaction, as the metal is gaining electrons (or losing oxygen) in the process. This reaction is referred to as a reduction because the metal is being reduced from a higher oxidation state to a lower one.
Is promethium a metalloid metal or nonmetal?
Yes, Promethium, element 61 is a metal just like the other members of the lanthanide group. Kilogram quantities of the material have been prepared and the metal purified in a method similar to the preparation of several other lanthanides, calcium reduction (calciothermic reduction) with a second vacuum distillation step to remove calcium (reducing agent) and magnesium (crucible material) impurities.
State the relation between reduction electrode potential of metal electrode and its tendency towards corrosion?
When the reduction electrode potential of the metal electrode increases there will be a tendency towards corrosion.
What Metal can be obtained from its oxide by reduction of carbon?
Iron (Fe)
