The given question is incomplete. The complete question is :
What is the coefficient of
when the following equation is properly balanced with the smallest set of whole numbers? 
Answer: The coefficient of
is 3
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical reaction is:

The coefficient of
is 3
The 2 parts or components that make up a solution would be the solute and the solvent.
We write the following substances' chemical formula as follows:
Ferric hydrogen sulphate = Fe(HSO4)3.<span>
Tungsten (V) peroxide = </span>W2(O2)5<span>
Nitric acid = HNO3
Aluminum acetate = </span>C6H9AlO6
Hope this answers the question. Have a nice day.

Answer:
F. a dark solid formed on the zinc.
-Is because when the solid is formed it is called the "precipitate", which is commonly know as chemical reaction.
Each acetyl coenzyme A proceeded once through the citric acid cycle<span>. Therefore, in total, it created 6 NADH + H+ molecules, two FADH2 molecules, four carbon dioxide molecules, and two ATP molecules. </span>
