Un átomo neutro tiene número atómico 1 y número másico 3. Indica cuántos protones, neutrones y electrones tiene.
ahrayia [7]

Answer:

El átomo podes 1 protón, 1 electrón y 2 neutrones.

Explanation:

Cada elemento químico se caracteriza por el número de protones de su núcleo, que se denomina número atómico Z. Es decir, el número atómico​ de un elemento químico es el número total de protones que tiene cada átomo de ese elemento.

Los protones poseen carga positiva y se encuentran en el núcleo, en torno al cual se mueven otras partículas con carga eléctrica negativa que son los electrones. Así, el átomo es eléctricamente neutro, ya que la carga positiva de los protones está compensada por la carga negativa de los electrones.  Entonces, en todo átomo neutro el número de protones del núcleo es igual al de electrones de sus orbitales.

En este caso, un átomo neutro tiene número atómico 1. Entonces la cantidad de protones y electrones presentes en el átomo es 1.

En el núcleo de cada elemento, además de protones, también es posible encontrar neutrones, cuyo número puede variar. La masa atómica (A) se obtiene sumando el número de protones y de neutrones de un núcleo determinado:

Número másico (A) = número de protones + número de neutrones

En este caso, el átomo neutro posee 1 protón y su número másico es 3. Entonces:

3= 1 + número de neutrones

Resolviendo:

3 - 1= número de neutrones

2= número de neutrones

Entonces,<u><em> el átomo podes 1 protón, 1 electrón y 2 neutrones.</em></u>

Looking at the car in the picture above, explain how the electrons act to form this compound that is on the surface of the car,
dmitriy555 [2]

Answer:

The correct answer is "Iron and oxygen act as Fe3+ and O2− ions respectively, forming rust (Fe₂O₃) in the presence of water by the formation of an ionic bond".

Explanation:

Rust is formed when iron reacts with oxygen in the presence of water (either if the iron is submerged or exposed to moisture in the air), forming the chemical compound Fe₂O₃. The presence of water is needed for rust formation because iron and oxygen act as ions when they are exposed to water, particularly Fe3+ and O2− ions respectively. The bond formed between these two elements are ionic bonds, because it is comprised of the reaction between a metal (iron) and a non-metal (oxygen).

Which of the following reactions shows that the rate of the appearance of D is twice the disappearance of A and one third the di
Delvig [45]
First, we are discussing reversible reactions here, since the reaction is proceeded in both directions forming both reactants and products.

The reaction is symbolized as:
A + B <.........> C + D

The first given is:
The rate of appearance of D is twice the disappearance of A
This means that the coefficient of D in the reaction is twice the coefficient of A

The second given is:
The rate of appearance of D is one third the disappearance of B.
This means that the coefficient of D in the reaction is 1/3 that of B. This also means that the coefficient of B is 3 times that of D.

Combining these two pieces of information, we will find that the best equation that resembles this scenario is:
<span>A + 6 B <.........> C + 2 D </span>
