I'm not so sure but I would say it could be an iconic bond!

The best answer among the choices is option D. New substances are being formed will best explain that this process is a chemical change. Although, it cannot be seen directly we knew that an acid and base will undergo neutralization reaction forming a salt and water. The heat given off by the reaction can be a parameter however it does not only happens for reactions. It can also happen when dissolving substances.

In the following reaction, identify the oxidized species, reduced species, oxidizing agent, and reducing agent. Be sure to answe
gtnhenbr [62]

Answer :

Cl_2 is reduced species.

KI is oxidized species.

Cl_2 is oxidizing agent.

KI is reducing agent.

Explanation :

Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.

Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.

Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.

Reducing agent : It is defined as the agent which helps the other substance to reduce and itself gets oxidized. Thus, it will undergo oxidation reaction.

Oxidizing agent : It is defined as the agent which helps the other substance to oxidize and itself gets reduced. Thus, it will undergo reduction reaction.

The balanced redox reaction is :

Cl_2(aq)+2KI(aq)\rightarrow 2KCl(aq)+I_2(aq)

The half oxidation-reduction reactions are:

Oxidation reaction : 2I^-\rightarrow I_2+2e^-

Reduction reaction : Cl_2^++2e^-\rightarrow 2Cl^-

From this we conclude that the 'KI' is the reducing agent that loses an electron to another chemical species in a redox chemical reaction and itself gets oxidized and 'Cl_2' is the oxidizing agent that gain an electron to another chemical species in a redox chemical reaction and itself gets reduced.

Thus, Cl_2 is reduced species.

KI is oxidized species.

Cl_2 is oxidizing agent.

KI is reducing agent.

What is the usual composition of acid etch?
Ratling [72]

Answer:

Explanation:acid etching  

etching

the cutting of a hard surface such as metal or glass by a corrosive chemical, usually an acid, in order to create a design.

etching  - etching of dental enamel with an acid in order to roughen the surface, increase retention of resin sealant, and promote mechanical retention.

acid etching

microscopic roughening of dental enamel with an acid (usually phosphoric acid) to remove the smear layer and open enamel tubules, increase retention of resin sealant, and promote mechanical retention.

acid etching Dentistry

The application of a weak acid—e.g., 30% phosphoric acid—to the surface of enamel to roughen the surface of a tooth before bonding a resin or veneer; acid etching increases mechanical retention, cleans the enamel and improves the wetting of resins. See Cosmetic dentistry.

La lección difícil, cuadro de William-Adolphe Bouguereau.

El aprendizaje es el proceso a través del cual se modifican y adquieren habilidades, destrezas, conocimientos, conductas y valores.1​ Esto como resultado del estudio, la experiencia, la instrucción, el razonamiento y la observación. Este proceso puede ser analizado desde distintas perspectivas, por lo que existen distintas teorías del aprendizaje. Es una de las funciones mentales más importantes en humanos, animales y sistemas artificiales. En él intervienen diversos factores que van desde el medio en el cual se desenvuelve el ser humano, así como los valores y principios que se aprenden en la familia. En esta última se establecen los principios del aprendizaje de todo individuo y se afianza el conocimiento recibido, el cual forma la base para aprendizajes posteriores.

El aprendizaje humano está relacionado con la educación y el desarrollo personal. Debe estar orientado adecuadamente y es óptimo cuando el individuo está motivado. El estudio sobre cómo aprender interesa a las Ciencias de la Educación, la pedagogía, la neuropsicología, la psicología educacional y la antropología, aquella que recoge las peculiaridades propias de cada etapa del desarrollo humano. Concibe sus planteamientos teóricos, metodológicos y didácticos para cada una de ellas. Dentro de ella se enmarcan, por ejemplo la pedagogía y la andragogía, la educación de niños y adultos respectivamente.2​
