Answer:
The common name for 2-butanone, a readily available solvent, is B-butanone
Answer:
Masses of bromobenzene molecular ions will occur at 156 and 158 m/z.
Explanation:
The molecular ion peak is the signal in the mass spectrum of a compound that represents the molecular ion (denoted as M). Compounds that are composed of atoms having abundant isotope also shows M +1 and M+2 peaks (depending on the isotope).
In the given bromobenzene compound, an atom of bromine is present. The two isotopes with considerable relative abundance of Br are 79Br and 81Br with a difference of two units in their mass. This means that two molecular ion peaks with a difference of two units will appear in the mass spectrum. The mass of the whole compound is 156 amu. Hence, the molecular ion peaks will appear at 156 m/z and 158 m/z due to the two isotopes of bromine.

If the hydrogen ion concentration of an unknown solution is 4.56E-7, the pH of the solution will be 6.34 and it will form an acid.
<h3>How to calculate pH from H+?</h3>
The pH, which is the power of hydrogen, can be calculated from the hydrogen ion concentration using the following expression:
pH = - log [H+]
According to this question, the hydrogen ion concentration of an unknown solution is 4.56E-7. The pH is as follows:
pH = - log [4.56E-7]
pH = 6.34
Therefore, If the hydrogen ion concentration of an unknown solution is 4.56E-7, the pH of the solution will be 6.34 and it will form an acid.
