The outcome of a experiment is the result
<u>Answer:</u> The balanced half reaction is written below.
<u>Explanation:</u>
Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
![X^{n+}+ne^-\rightarrow X](https://tex.z-dn.net/?f=X%5E%7Bn%2B%7D%2Bne%5E-%5Crightarrow%20X)
When oxygen gas is reduced to oxide ions, the number of electron transferred are 2
The chemical equation for the reduction of oxygen gas to oxide ions follows:
![O_2+2e^-\rightarrow 2O^{2-}](https://tex.z-dn.net/?f=O_2%2B2e%5E-%5Crightarrow%202O%5E%7B2-%7D)
Hence, the balanced half reaction is written above.
The molecular mass of
is:
2·1 + 1·32 + 4·16 = 98 g/mol
The amount of solute, expressed by mol, is:
![73.5\ g\ H_2SO_4\cdot \frac{1\ mol}{98\ g} = 0.75\ mol\ H_2SO_4](https://tex.z-dn.net/?f=73.5%5C%20g%5C%20H_2SO_4%5Ccdot%20%5Cfrac%7B1%5C%20mol%7D%7B98%5C%20g%7D%20%3D%200.75%5C%20mol%5C%20H_2SO_4)
The molar concentration definition is: ![M = \frac{mol\ solute}{volume (L)\ solution}](https://tex.z-dn.net/?f=M%20%3D%20%5Cfrac%7Bmol%5C%20solute%7D%7Bvolume%20%28L%29%5C%20solution%7D)
Doing the calculations:
![M = \frac{0.75\ mol}{3\ L} = \bf 0.25\ M](https://tex.z-dn.net/?f=M%20%3D%20%5Cfrac%7B0.75%5C%20mol%7D%7B3%5C%20L%7D%20%3D%20%5Cbf%200.25%5C%20M)

A monomer is a single unit. While a polymer is monomers linked together. So your answer would be B.) A collection of monomers combines to form a polymer.
