What is the balanced equation when chromium reacts with water?
The balanced equation for the reaction of chromium with water is: 2 Cr + 6 H2O -> 2 Cr(OH)3 + 3 H2.
What does chromium react to?
Under still milder conditions, chromium metal reacts with the halogens fluorine, F2, chlorine, Cl2, bromine, Br2, and iodine, I2, to form the corresponding trihalideschromium(III) fluoride, CrF3, chromium(III) chloride, CrCl3, chromium(III) bromide, CrBr3, or chromium(III) iodide, CrI3.
What is the element chromium's reactivity to Oxygen?
Chromium reacts directly with fluorine, F2, at 400°C and 200-300 atmospheres to form chromium(VI) fluoride, CrF6. Cr(s) + 3F2(g) → CrF6(s) [yellow] Under milder conditions, chromium(V) fluoride, CrF5, is formed. 2Cr(s) + 5F2(g) → 2CrF5(s) [red] Under still milder conditions, chromium metal reacts with the halogens fluorine, F2, chlorine, Cl2, bromine, Br2, and iodine, I2, to form the corresponding trihalides chromium(III) fluoride, CrF3, chromium(III) chloride, CrCl3, chromium(III) bromide, CrBr3, or chromium(III) iodide, CrI3. 2Cr(s) + 3F2(g) → 2CrF3(s) [green] 2Cr(s) + 3Cl2(g) → 2CrCl3(s) [red-violet] 2Cr(s) + 3Br2(g) → 2CrBr3(s) [very dark green] 2Cr(s) + 3I2(g) → 2CrI3(s) [very dark green]
What is the formula when fluorine and chromium react?
Chromium fluorides are: Chromium difluoride: CrF2 Chromium trifluoride: CrF3 Chromium tetrafluoride: CrF4 Chromium pentafluoride: CrF5 Chromium hexafluoride: CrF6
Compound name for chromium bromide?
Another chemical name is chromium trichloride or chromic chloride. Chromium(III) chloride is a chemical name as well.
What happens when chromium reacts with potassium bromate?
Oxygen is transferred from bromate ion(s) to the Chromium ion. Leaving hypobromous ion, and/ or bromide ion.

What is the green precipitate in preparation of chromium oxalate complexes?
No green precipitate should found but green but green heavy solution that can be filterated through the filter paper but white crystaline precipitate in a shape of needle or cylindrical flakes .
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 is the isotopes of chromium 151?
The stable isotope of chromium is chromium-52. Other isotopes of chromium include chromium-50, chromium-53, chromium-54, and chromium-55, but not chromium-151.
What is an chromium?
Chromium is a 3d element. chromium is a metal.

What is chromium ore used for?
Chromium ore is a source of the metal Chromium.
Is silicon more reactive than chronium?
Silicon is less reactive than chromium. Silicon forms a protective oxide layer when exposed to air, preventing further reaction with oxygen. Chromium, on the other hand, readily reacts with oxygen to form a stable oxide layer, which provides corrosion resistance.
