Answer:
1. the effects of punishment.
Explanation:
Stanley Milgram (1933 - 1984) was a graduate American psychologist at Yale University who conducted the Little Worlds Experience (the source of the concept of the six degrees of separation) and the Milgram Experience on obedience to authority.
Milgram was interested in researching how far people would go in obeying an instruction if it involved harming another person.
The study aimed to observe how easily ordinary people could be influenced into committing atrocities.
0.04 m urea > 0.03 m CuSO4 > 0.01 m AgNO3.
<h3>What is colligative property?</h3>
- Colligative properties in chemistry are those of a solution that depend on the amount of solute particles to solvent particles in a solution rather than the makeup of the individual particles.
- The number ratio can be connected to the several units used to measure a solution's concentration, including molarity, molality, normalcy (chemistry), etc.
- For ideal solutions, which are ones that have thermodynamic properties similar to those of an ideal gas, and for diluted actual solutions, the assumption that solution properties are independent of the type of solute particles is exact.
<h3>What factors affect colligative properties?</h3>
- A property of a solution is said to be collative if it depends simply on the proportion of solute to solvent particles in the solution and not on the nature of the solute.

Answer:
S = 0.2 E-7 M
Explanation:
- molar solubility (S) [=] mol/L
S S 2S + 0.4
∴ [F-] = 0.4 m = 0.4 mol/Kg
∴ solvent: H2O ⇒ δH2O = (997 Kg/m³)*(m³/1000L) = 0.997 Kg/L
⇒ [F-] = (0.4 mol/Kg)*(0.997 Kg/L) = 0.3988 M ≅ 0.4 M
∴ Ksp = 6.4 E-9 = [S]*[2S + 0.4]²
⇒ 6.4 E-9 = (S)*(4S² + 1.6S + 0.16)
⇒ 6.4 E-9 = 4S³ + 1.6S² + 0.16S
⇒ 4S³ + 1.6S² + 0.16S - 6.4 E-9 = 0
⇒ S = 0.2 E-7 M
