Answer:
Explanation:
1. Convert millilitres to litres
2. Calculate the concentration
In this item, it is assume that we are to express the dissociation of the formula unit given to be FeCl₂ into its ionic components.
As seen in the chemical formula, the unit is composed of iron (Fe) and chlorine (Cl). The dissociation is written as follows;
FeCl₂ --> Fe²⁺ + Cl⁻
This equation is balanced by multiplying the appropriate component with a number that would equate the number of atoms in both sides of the equation.
<em> FeCl₂ --> Fe²⁺ + 2Cl⁻</em>
Answer:
At a front, the two air masses have different densities, based on temperature, and do not easily mix. One air mass is lifted above the other, creating a low pressure zone.

Today I will explain what a valence electron is and how many valence electrons each of the atoms your asking about have. :)
→ A valence electron is an electron in the outer shell of an atom that is able to participate in bonding. While iodine has 53 electrons, all but seven are in the inner shells of the iodine atom.
→ Sulfur has sixteen electrons in total, two in the inner shell, eight in the middle, and six in the outer. This means that sulfur has six valence electrons.
