No.
In tap water, you will most likely find iron. In distilled or deionized water, no.
Iron sulfide is a pure compound. It can be as in aqueous medium too as a solution.
No. Iodine is itself a chemical element; it contains no other element. If you mean instead tincture of iodine that has no iron in it either. It's a solution of iodine and an iodide in ethanol and water.
A displacement reaction occurs when a more reactive element displaces a less reactive element in a compound. In this case, iron is more reactive than copper and displaces it in the copper-sulphate solution to form iron sulphate and copper metal.
No, iron is not an electrolyte. Electrolytes are substances that produce ions when dissolved in water and can conduct electricity, while iron is a chemical element that does not easily form ions in solution.
Sand is NOT an element. Iron IS an element.
Iron is a element, it isn't a compound
iron (i.e., pure) is a metal / element in the periodic table, but types of iron are compounds like wrought iron, pig iron cast iron., etc.
No. It is not. Iron is an element. Oxygen is an element. Iron Oxide is a compound.
Iron is an element. It is a pure substance that consists of only one type of atom, specifically iron atoms.
Iron is not soluble in alcohol. Iron is a metallic element that does not dissolve in alcohol, which is a polar solvent. If you need to dissolve iron in a solution, you would typically use an acid or other specialized solvents.
Iron (III) combines with the thiocyanate ion (SCN-) to make Iron Thiocyanate, which is a blood red compound. The two solutions most commonly used to make Iron Thiocyanate are Iron (III) Chloride (clearish yellowish brownish solution) and Potassium Thiocyanate (clear solution).
