Answer:

Mira la explicación.

Explanation:

Hola,

Las reacciones de oxidación se definen como aquellos procesos químicos en las cuales uno de los elementos involucrados sufre un aumento en su estado de oxidación, causado por el efecto de un agente oxidante, el cual es capaz de aceptar los electrones perdidos por dicho elemento oxidante. Dentro de los factores promotores de la oxidación se pueden encontrar:

1. Presencia de oxígeno gaseoso: al ser un agente oxidante fuerte, es capaz de recibir electrones de casi cualquier sustancia.

2. Presencia de humedad: a la larga, cuando una sustancia reacciona con agua tiende oxidarse ya que el agua posee oxígeno y como se vio anteriormente, es el principal promotor de oxidación.

3. La presencia de algunas sales iónicas como cloruro de sodio también promueven la oxidación, por ello es que no debemos introducir joyería al mar, debido a que esta salinidad induce reacciones electroquímicas que son capaces de oxidar metales.

4. Reacciones con ácidos oxidantes: ácidos como el nítrico, son oxidantes fuertes que tienen la capacidad de disolver metales (oxidarlos) y formar nitratos, por ejemplo el cobre en presencia de ácido nítrico, sufre una oxidación bastante violenta.

Saludos!

What is the specific latent heat of fusion of ice if it takes 863 kJ to convert 4.6 kg of ice into water at 0 C?
charle [14.2K]

Answer:

The correct answer is 187.7 J/Jg.

Explanation:

The formula for finding the specific heat of fusion is,  

Specific heat of fusion = Q/m

Here Q is the heat energy added, signified in kJ, and m is the mass of the object in kg.  

Based on the given information, the heat energy added or Q is 869 kJ and the mass of the ice is 4.6 Kg

Now putting the values in the formula we get,  

Specific heat of fusion = Q/m

Specific heat of fusion = 863 kJ / 4.6 Kg = 187.7 J/Kg

Explain why the coin is able to float on top of the water in this glass.
zubka84 [21]
Surface tension is the result of water molecules pulling inward with a strong attractive force. 
The attractive force brings the molecules on the surface of the water close together.
The attractive force causes the surface of the water to be drawn toward the water molecules beneath the surface. <span>
Since there are no water molecules above the surface, there are uneven forces. This causes surface tension, allowing the coin to float on the water’s surface.</span>
