Answer:

A. When an endothermic reaction has a positive change in entropy and the temperature is greatly increased

Explanation:

An spontaneous reaction is one that occurs without having been provoked by an external influence. The non-epontaneous reaction, on the other hand, is one that occurs only when they are induced in the opposite direction.

Most of the non-spontaneous reactions are endothermic, that is, they occur with the absorption of energy. An example of a non-spontaneous reaction occurs when a metal needs to be heated to increase its temperature. The heating of a metal is very difficult to occur naturally, without an external factor that provokes the reaction.

However, a non-spontaneous reaction can become spontaneous depending on the entropy of the system. Entropy in an isolated system tends to increase when an spontaneous reaction occurs. Therefore, in order for a non-spontaneous reaction to become spontaneous it is necessary that an endothermic reaction has a positive change in entropy and the temperature increases a lot.

Small amount of acid is added to Water during electrolysis of water . Why?

Answer:

Water doesn't have ions that are needed to pass the electricity so in order to increase the no of ions we poor acid into the water. Just increasing the no ions will increase the electricity flow faster

Explain how the change in free energy determines the direction of a chemical reaction and how chemical reactions eventually reac

ohaa [14]

<span>Free energy refers to exactly that "energy that is free to perform and/or have a reaction." Also known as Gibbs (G) It is energy that is associated with a chemical reaction and is used for work. You also need 3 other variables: heat, temperature, and entropy. The formula for the above would be: G = H - T (E)</span>

Which of the following molecules is amphipathic?

raketka [301]

Answer:

B) CH3(CH2)10CO2H

Explanation:

Hello,

In this case, we define amphipathic as a compound having both a hydrophilic and a hydrophobic part, for that reason, the hydrophilic part will be water-soluble (polar) whereas the hydrophobic does not (nonpolar). In such a way, some functional groups such as hydroxyl and carboxyl tend to be polar by cause of the presence of O-H bonds whereas long-carboned chains tend to be nonpolar by cause of the presence of C-H and C-C bonds.

Therefore, since A) CH3CH2OH (ethanol) and D) CH3CO2H (acetic acid) are short-carboned chains with polar groups they are largely hydrophilic whereas C) CH3(CH2)10CH3 (dodecane) is highly nonpolar, we sum up that only B) CH3(CH2)10CO2H (dodecanoic acid or lauric acid) is amphoteric as it has a long-charboned part (nonpolar) and a water-soluble part (polar).

Best regards.

Why don't the particles in a solid move past one another?

zlopas [31]

Answer:

the attractive forces keep the particles together tightly enough so that the particles do not move past each other.

Explanation:

In the solid the particles vibrate in place.
