Answer:
The answer is a) ![C_{4} H_{16} O_{5}](https://tex.z-dn.net/?f=C_%7B4%7D%20H_%7B16%7D%20O_%7B5%7D)
Explanation:
The other chemical formulas' subscripts share a common factor, so they can be simplified to an empirical formula, however, the subscripts in
cannot be simplified any further, because they do not share any more whole-number factors with each other.
The question is in complete, complete question is :
Balance each of the following chemical equations. (Use the lowest possible coefficients for all reactions.

Answer:
Explanation:
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side or total number of all atoms of each elements on reactant sides are equal to the total number of all atoms of each element on product side
