What is the formula mass of FeCl2?

What is the formula mass of FeCl2?

126.751 g/mol
Iron(II) chloride/Molar mass

What is the charge of FeCl2?

Since the oxidation number for Cl- is always -1, and there are two Cl- in the formula FeCl2 (total negative charge = -2), then Fe must have an oxidation number of +2 to balance the 2 Cl-. Cl-(aq): -1. Since iron is in the oxidation state +2, the compound is called iron (ii) chloride.

What is the compound name of FeCl?

Iron trichloride
Iron(III) chloride
Iron(III) chloride/IUPAC ID

How do you find the empirical formula?

Calculate the empirical formula.

  1. In any empirical formula problem you must first find the mass % of the elements in the compound.
  2. Then change the % to grams.
  3. Next, divide all the masses by their respective molar masses.
  4. Pick the smallest answer of moles and divide all figures by that.

What is the mass of Fe?

55.845 u

What is the structure of FeCl2?

Iron(II) chloride

Crystal structure Monoclinic
Coordination geometry Octahedral at Fe

Is FeCl2 a strong acid?

Answer: HBr is strong electrolyte because of it dissociates completely and HBr is a strong acid. FeCl2 is strong electrolyte because of it dissociates completely. H2CO3 is a weak electrolyte because of it dissociates slightly.

What is the correct electron configuration for Fe3 +?

How does ferric chloride decompose to FECL 2?

In one of two classic syntheses of ferrocene, Wilkinson generated FeCl 2 in situ by comproportionation of FeCl 3 with iron powder in tetrahydrofuran (THF). Ferric chloride decomposes to ferrous chloride at high temperatures.

Where does the dihydrate FECL 2 H 2O 2 crystallize?

The dihydrate, FeCl 2(H 2O) 2, crystallizes from concentrated hydrochloric acid. The dihydrate is a coordination polymer. Each Fe center is coordinated to four doubly bridging chloride ligands. The octahedron is completed by a pair of mutually trans aquo ligands.
