The simplest level at which life may exist is a cell
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 molar concentration of potassium ions in a 0. 250 m K₂SO₄(aq) solution is 2.
<h3>What is molar concentration?</h3>
The molar concentration of a solution is the presence of solute in one unit of a solution.
Molar concentration = number of moles / volume
The volume is given 0.250 m
To calculate the number of moles:
There will be 2 moles of potassium and 1 mole of sulfate in one L of the solution.
So in 0.250 L
0.250 x 2 x 1 = 0.500
The total number of moles of potassium and sulfate ion are 0.500
Now, putting the value:
Molar concentration = number of moles / volume
0.500 / 0.250 = 2
Thus, the molar concentration is 2.

Answer:
New Gas volume (V2) = 5.86 L
Explanation:
Given:
Gas volume (V1) = 2.93 L
Temperature (T1) = 20°Celsius
After Increasing temperature:
New Temperature (T2) = 40°Celsius
Find:
New Gas volume (V2) = ?
Computation:
According to Charles' gas Law:
⇒ Gas volume (V1) / Temperature (T1) = New Gas volume (V2) / New Temperature (T2)
⇒ 2.93 L / 20°Celsius = New Gas volume (V2) / 40°Celsius
⇒ New Gas volume (V2) = 5.86 L
