What alloy is nichrome made of?
nichrome alloy is made by mixing up of the metals nickel and chromium.
What is the chemical make up of hexavalent chromium?
It is a valence of chromium. The hexavalent chromium is present in anions as CrO42- and Cr2O72-.
Does chromium react with any elements?
Chromium reacts with oxygen from the atmosphere to form the oxide Cr2O3, which is a type of metal oxide that is non-destructive as opposed to iron oxide. This property is used to protect steel when chromium is added to the molten metal to form an alloy with up to 30% chromium and is commonly known as "Stainless Steel". The Chromium oxide protects the metal from further oxidizing. Chromium will react with a number of other elements if the conditions are suitable. The most common is forming a carbide by reacting with carbon during the smelting process of Ferrochrome. This is typically and unwanted reaction in the process.
What element starting with c isn't made up of small molecules?
Several examples include the metals cesium, Cs, calcium, Ca, cobalt, Co, chromium, Cr, copper, Cu, and cadmium, Cd, ... .
What is eloctroplating?
Electroplating is a Platingprocess in which metal ions in a solution are moved by an electric field to coat an electrode. The process uses electrical Direct_currentto RedoxCationof a desired material from a solution and coat a Electrical_conductivityobject with a thin layer of the material, such as a metal. Electroplating is primarily used for depositing a layer of material to bestow a desired property (e.g., Abrasion_(mechanical) and wear resistance, Corrosionprotection, Lubrication, aesthetic qualities, etc.) to a surface that otherwise lacks that property. Another application uses electroplating to build up thickness on undersized parts.(From wikipedia)
Anode current in an thyristor is made up of?
Holes and electrons
What alloy is nichrome made of?
nichrome alloy is made by mixing up of the metals nickel and chromium.
What is the chemical make up of hexavalent chromium?
It is a valence of chromium. The hexavalent chromium is present in anions as CrO42- and Cr2O72-.
Why anode is eaten up in electrorefining process?
In electrolytic refining,anode contains the impure aopper and when current passes through solution all the impure copper ions from anode dissolve in solution and thus when all ion discharge anode becomes empty and thus eaten up.
How is chromium made?
Chromium applications: Alloying component of steels and copper alloys, tanning agent, important chemical compounds used in analytical chemistry (potassium dichromate for titrations, cleaning agent with sulfuric acid), glasses pigment, food additive, plating of metals, magnetic tapes coatings, abrasive, refractory materials, etc. Another very common example: kitchen ware from stainless steel with high content of chromium.
Are there any other names for the ruby?
no there is no other names for ruby in English. ruby is a mineral made up of aluminum oxide with chromium.
What happens to voltage as you move the anode and cathode closer in a fruit battery?
the voltage will go down when the anode and cathode are closer together but will go up when they are further apart
Why chromium is in d block?
This is because the D-Block in the Periodic Table is where the d-Subshell is being filled up. Chromium's d-Subshell is being filled up and is therefore in the D-Block.
What elements make up a corundum?
aluminumoxide, iron, titanium, chromium
Is CrO2 an ionic or covalent bond?
Chromium oxide (Cr2O3) is an ionic compound, since it is made up of a metal and a nonmetal.
Explain the process of electroplating of copper?
metal ions form a solid layer on a metal cathode
Why is gas obtained at the cathode double at the anode?
Hydrogen is produced at the anode at twice the rate of oxygen produced at the cathode, because of the ratio of hydrogen to oxygen that makes up water: 2 : 1.
