The correct answer is <em>B. a Salt </em><em>because The reaction of an acid and a base is called a neutralization reaction because the properties of both the acid and base are diminished or neutralized when they react. A neutralization reaction is a reaction of an acid with a base in aqueous solution to produce water and a salt, as shown by the following equation:</em>
<em>acid + base → salt + water</em>

<span>The shininess of an element is also referred to as "metallic luster." The element that is most likely to have a metallic luster is B. rhodium.
Arsenic has a dull luster, chlorine and hydrogen are gases so they don't have luster.

Explanation:
(a) As per the mole concept, one mole of any atom contains 
atoms or molecules, that is, Avogadro's number of atoms.
Therefore, 1 mole of 
= 
molecules
= 
molecules
1 mole of 
= molecules
= molecules
1 mole of 
= molecules
= molecules
Hence, there are equal number of molecules present in the given atoms.
(b) Mass of each given atom will be calculated as follows.
Mass = no. of moles × molar mass
As one molecule of contains 2 atoms of hydrogen.
So, mass of 1 mole of = 
= 2.016 g
mass of 1 mole of = 
= 31.996 g
mass of 1 mole of = 
= 37.996 g
Thus, we can conclude that has the greatest mass.
The reaction that best describes the change of aniline into phenyl isocyanide is
<span>C6H5NH2 + CHCl3 + KOH → C6H5NC + 3KCl + 3H2O
</span>
This is basically a characteristic reaction of the primary amines. <span> from the above reaction, we can see that aniline on carbyl amine reaction gives phenyl iso-cyanide.</span>
