The specific gravity or relative density of a substance is the ratio of its density to the density of a reference material. The relative density of the concentrated salt solution is 1.044.
Mathematically;
Density of the concentrated salt = mass of salt/volume of salt = 5.222 g/5.000 mL = 1.044 g/mL
In the case of specific gravity, the reference material is always water and water has a density of 1 g/mL.
Hence, specific gravity of the concentrated salt solution =
Density of concentrated salt solution/density of equal volume of water
= 1.044 g/mL/1 g/mL
= 1.044
Note that specific gravity is dimensionless.

Answer:
Iodine is most reactive because it is very close to having a "full shell" which is 8 electrons so they are "eager" to gain the last electron to became balanced, so that makes it the most reactive. Hope that helps:)
Explanation:
The balanced form of the chemical equation shown is N₂(g) + 3H₂(g) → 2NH3(g) (option A).
<h3>What is a balanced equation?</h3>
A chemical equation is said to be balanced when the number of atoms of each element on both sides of the equation is the same.
According to this question, the chemical equation between nitrogen and hydrogen is given as follows: N₂(g) + H₂(g) → NH3(g)
The balanced form of the chemical equation shown is N₂(g) + 3H₂(g) → 2NH3(g).
