When chemical x is reduced, which of these expressions would be an accurate representation of its reduced state? xo xh x hx

XH will be the accurately presentation of the reduced state.  

Explanation:

Generally, Reduction types of reaction in nature oxidation and reduction reaction. Oxidation reaction is defined as the reaction in which there is removal of electron or addition of oxygen. Reduction reaction is defined as the reaction in which there is addition of electron or addition of hydrogen.

Hence, we can see that when chemical x is reduced it means there is addition of hydrogen or addition of electron. Therefore, among the options XH will be inaccurate representation of the radius is state of chemical x.

the correct option is option d
