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>
The criteria for designation as a biodiversity hotspot include species richness, endemism, and risk of extinction.
<h3>What is a biodiversity hotspot?</h3>
A biodiversity hotspot is a region having high levels of biodiversity in its communities and ecosystems.
A biodiversity hotspot must have a high number of endemic vascular plants (at least 1500 species).
In conclusion, the criteria for designation as a biodiversity hotspot include species richness, endemism, and risk of extinction.
