What is the formula unit for a compound made from fe2+ and oxygen? ofe feo fe2o o2fe

The formula unit for the compound obtained will be

Explanation:

A compound is formed by the reaction of two or more different elements.

When Iron reacts with oxygen, it leads to the formation of oxide of iron.

Iron exists in different oxidation states. The oxidation state of iron given here is +2 and oxygen has an oxidation state of -2.

Hence, by criss-cross method, the compound formed will be

FeO is the formula unit for a compound made from and oxygen.

Explanation:

Ionic compounds are defined as the compounds which have ionic bond between the atoms.Two ion of opposites charges are  combine with each other with help of ionic bonding that complete transfer of electrons from one atom to another.

Iron is the 26th element of the periodic table with electronic configuration of

In the naming of the compound, the oxidation state of this element is given +2.

Oxygen is the 8th element of the periodic table with electronic configuration

This element will easily gain 2 electrons and shows an oxidation state of -2.

By criss-cross method, the oxidation state of titanium and oxygen gets reversed and they form the coefficients of the compound.

The compound formed by the combination of Titanium(III) and oxygen is

the answer for sodium is 0.186

the answer for rubidium is 0.251
