How many unpaired electrons would you expect on iron in iron ii sulfide. enter an integer?

Answer : The number of unpaired electrons present on iron in iron(II) sulfide are, 4

Explanation :

The given compound is, FeS

In this compound, iron is in (+2) oxidation state and sulfur is in (-2) oxidation state.

As we know that, iron is a d-block element and the atomic number of iron is 26. That means, there are 26 number of electrons.

The electronic configuration of iron is:

The electronic configuration of Fe²⁺ will be:

Thus, there are 4 unpaired electrons present on iron in iron(II) sulfide.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
