The structure of an individual  molecule will determine which substance  will dissolve.

<u>Option: A</u>

<u>Explanation:</u>

Once a solvent disintegrates, the single atoms, molecules or ions communicate with the solvent, become solved, and are able to diffuse in the solution independently. However, this is not a unidirectional method. When the molecule or ion collides with the surface of an undissolved solute particle, it may bind to the particle in a method called crystallization.

The concentration units or structure are used to define the degree to which a solvent is soluble. A solution can be categorized as hydrophilic (water-loving), implying it has an electrostatic water-looking attraction, or hydrophobic (water-fearing), implying it repels water. A hydrophilic material is polar, and mostly includes groups of O–H or N–H that can shape water bonds.

While traveling along a highway a driver slows from 34 m/s to 17 m/s in 6 seconds. What is the automobiles acceleration?​
xxTIMURxx [149]

Answer:

-2.83 m/s²

Explanation:

  • Initial velocity (u) = 34 m/s
  • Final velocity (v) = 17 m/s
  • Time taken (t) = 6 seconds

❖ Acceleration is defined as the rate of change in velocity with time.

→ a = (v - u)/t

  • v denotes final velocity
  • a denotes acceleration
  • u denotes initial velocity
  • t denotes time

→ a = (17 - 34)/6 m/s²

→ a = -17/6 m/s²

<h3>→ Acceleration = -2.83 m/s²</h3>

(Minus sign implies that the velocity is decreasing.)

OlgaM077 [116]
The IRB at the university will decide whether her study meets ethical guidelines before it is initiated. The importance of these codes of conduct is to safeguard research participants, the status of psychology and the researchers or psychologists themselves. Moral issues hardly yield a simple, unequivocal, right or wrong answer. It is consequently often a matter of judgment whether the research is justified or not. For instance, it might be that a study roots psychological or physical uneasiness to participants, maybe they agonize pain or maybe even come to solemn harm.
