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>

383 mL of 3.50 M muriatic acid solution
Explanation:
First we calculate the number of moles of HCl:
number of moles = mass / molecular weight
number of moles of HCl = 47.7 / 35.5 = 1.34 moles
Now to determine the volume of the 3.50 M muriatic acid (clorhidric acid) solution, we use the following formula:
molar concentration = number of moles / volume (L)
volume (L) = number of moles / molar concentration
volume of the muriatic acid solution = 1.34 / 3.5 = 0.383 L = 383 mL

Answer:
A covalent bond is formed by an equal sharing of electrons from both the participating atoms. The pair of electrons participating in this type of bonding is called shared pair or bonding pair. The covalent bonds are also termed molecular bonds.
