The Ksp shows the extent of dissolution of a solute in solution. The Ksp of the solution is 2.5 * 10^-4.
<h3>What is Ksp?</h3>
The Ksp is an equilibrium constant that is usd to show the extent of solubility of a solute in solution.
The equation for the solution of X2S is;
X2S(s) ⇄2X^+(aq) + S^2-(aq)
Ksp = [2s]^2 [s]
Since s = 0.0395 M
Ksp = 4s^3
Ksp = 4[0.0395 ]^3
Ksp = 2.5 * 10^-4

Answer:
3.53 g
Explanation:
To convert from atoms to moles, you need to know Avogadro's number. Avogadro's number (6.022 × 10²³) is how many atoms there are in one mole of a substance. Use this to convert.
(1.97 × 10²² atoms) ÷ (6.022 × 10²³ atoms/mol) = 0.0327 mol
Now that you have moles, use the molar mass to convert to grams.
(0.0327 mol) × (107.87 g/mol) = 3.53 g
Explanation:
(a) A number which is dimensionless and provides us an estimate of the degree of conversion which can be achieved in CSTR, that is, continuous stirred tank reactor is known as Damkohler number.
This number is denoted as Da.
Mathematically, Da = 
Da = 
Now, for first order system, Da = 
=
= Tk
where, rA = rate of reaction
V = volume of reactor
= molar flow rate of component A
k = rate constant
= initial concentration of A
v = volumetric flow rate of A
T = residence time
(b) Since, from a given Damkohler number we can figure out the possible conversion of CSTR, that is, continuous stirred tank reactor.
So, if we have a low Damkohler number then the system will give us a less conversion formula. As the conversion is as follows.
X = 
Hence, we can conclude that
will give less than 10% conversion as calculated by using above formula.
Potential energy
Reason why: because the quarterbacks arm has the potential to throw a ball but since it is not throwing the ball, the energy is being held... this holding of energy is called potential energy
