The melting point of phenol is 40.5∘C and that of toluene is −95∘C. What is the best explanation for this difference? Select the
romanna [79]

Answer:

None of the above

Explanation:

The (−OH) group on phenol can form hydrogen bonds, and the −CH3 group on toluene cannot.

Phenol has only one hydrogen on the −OH group available to form hydrogen bonds, so the hydrogen bond is stronger. In toluene, the hydrogen bond is spread over all three hydrogens on the methyl group, so the interaction is weaker overall.

Phenol has a higher molecular mass than toluene.

If one body is positively charged and another body is negatively charged, free electrons tend to
Naily [24]
I think the correct answer is A. If one body is positively charged and another body is negatively charged, free electrons tend to <span>move from the negatively charged body to the positively charged body. This happens because they have different charges and therefore electrons are more attracted to the positive or its opposite charge.</span>

Frases con masa atómica
zzz [600]

Answer:

Si ha mirado una tabla periódica, es posible que haya notado que la masa atómica de un elemento rara vez es un número par. Dupdo

Un Dalton, también conocido como unidad de masa atómica, es aproximadamente la masa de un solo protón o neutrón. Dupdo

Es decir, el deuterio tiene el doble de masa atómica que el protio y el tritio tiene tres veces la masa atómica del protio. Dupdo

El número bariónico, que es equivalente al número de masa atómica, debe permanecer constante para que se produzca una reacción.

(CH3)3N + H2O ---> (CH3)3NH+  +  OH-

The equation of Kb:

Kb = [(CH3)3NH+][OH-]/[(CH3)3N]

<h3>What do we know about the process of dissolution?</h3>

A solute can dissolve in a solvent in a solid, liquid, or gaseous phase to create a solution through the process of dissolution. Solubility. The greatest amount of a solute that may dissolve in a solvent at a particular temperature is known as its solubility. The solution is said to as saturated when the maximum amount of solute is present.

Several variables influence solubility, including:

  • The solute's concentration
  • The system's temperature
  • Pressure (for gases in solution)
  • The solvent's and solute's polarity
