Answer:

resonance

Explanation:

Resonance is the phenomenon that explains the bonding in the certain molecules or the ions by combination of different contributing structures into the resonance hybrid.

Resonance structures are the set of two or more than two Lewis Structures which collectively describe bonding of the molecule by using fractional bonds and fractional charges.

Consider the case of benzene, in which there are three double bonds and three single bonds but the actual bond length of the C-C bond in benzene is in between single and double bond. This is because of resonance.

What are the differences between boiling and evaporation
Gnesinka [82]

Answer/Explanation:

Let's define both terms

Boiling: is defined as a process whereby the liquid state is turned into gaseous state at a specific boiling point. And it is a fast process.

Evaporation: is defined as a process whereby a natural process in which the increase in temperature or pressure causes liquid to change into gas.

Difference between boiling and evaporation

In boiling, temperature of the liquid remains constant. While in evaporation, temperature of the liquid reduces

In boiling, temperature is required only at boiling point while in evaporation, temperature occurs at any given temperature.

In boiling, bubbles are formed while in evaporation, bubbles are not formed.

In boiling, a source of energy is required while in evaporation, the surrounding supplies the energy required.

Boiling produces heat and does not lead to liquid cooling, evaporation leads to liquid cooling.

The molecules of the liquid move faster in boiling than in evaporation

Si en un planeta la presión atmosférica es mayor que 5,1 atm terrestres, los habitantes podrían nadar en ríos de dióxido de carb
Sphinxa [80]

Answer:

Los habitantes del planeta con una atmósfera superior a 5,1 atm de la Tierra, no estarían nadando en ríos de dióxido de carbono líquido

Explanation:

De las tablas de datos termodinámicos, la presión a la que el vapor de dióxido de carbono está en equilibrio con su estado líquido a una temperatura ambiente de 25 ° C es 6,401 kPa, lo que equivale a 63,17296 atm.

Por lo tanto, a una presión de 5.1 de la atmósfera terrestre, el dióxido de carbono es completamente gaseoso y los habitantes del planeta con una presión atmosférica de 5.1 atm de la Tierra todavía observarían solo hidrógeno gaseoso y no estarían nadando en ríos de dióxido de carbono líquido.

Which is the best explanation for why a dart is in motion when u throw it at a dart board​
Greeley [361]

Answer:

Its kinetic energy

Explanation:The dart is in motion because of the potential energy being stored and turned into kinetic energy, plus since the dart is aerodynamic, it would have more speed for it to hit the dart board.

What is Saponification!?
Tom [10]

Answer:

<h3>Saponification is a process that involves conversion of fat, oil or lipid into soap and alcohol by the action of heat in the presence of aqueous alkali. Soaps are salts of fatty acids and fatty acids are monocarboxylic acids that have long carbon chains e.g. sodium palmitate.</h3>
