The formula unit for the compound obtained will be FeO

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

FeO is the formula unit for a compound made from $Fe^{2+}$ 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 1s^22s^22p^63s^23p^64s^23d^6

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

$[Fe]^{2+}=1s^22s^22p^63s^23p^63d^6$

Oxygen is the 8th element of the periodic table with electronic configuration 1s^22s^22p^4

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

$[O]^{2-}=1s^22s^22p^6$

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 FeO

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
