I believe the answer is orbital hybridization theory
I really don’t know the answer, please help this kiddo with his question
Answer:
Electrones de valencia.
Explanation:
¡Hola!
En este caso, dado en química se conocen las estructuras de Lewis como representaciones gráficas de como los elementos están enlazados entre sí, debemos tener en cuenta que estos enlaces se forman entre los electrones de valenciam, los cuales son utilizados para su representación. Se sabe que los electrones de valencia son representados con puntos alrededor del elemento a través de puntos que se unen entre sí y son el número de electrons en la capa más externa de los elementos en cuestión; por ejemplo, cloro tiene 7 electrones de valencia, azufre tiene 6, hidrogeno 1, carbono 4 y así sucesivamente.
¡Saludos!
Answer:
Option (3) southern states threatened to secede from the Union over the issue of slavery
Explanation:
By the 18th century, the United States faced a number of issues. For example, the slave trade was one of the issues that resulted in the state being brought into turmoil. This was because the United States was already divided into two - the Northern region and the Southern region. The Northern region was the one region that still held to slave trade despite it being abolished. The South, offered slaves freedom. Thus, the movement of he slaves from the North to the South was a major issue. Thus, the war was over the trade as the north though it was suffering due to the decrease in slave labor.
Answer:
1. frequency = 7.39 * 10¹⁴ Hz
2. wavelength = 1.44 * 10⁸ nm
Explanation:
The speed, frequency and wavelength of waves are related by the formula;
speed = wavelength * frequency
1. wavelength of light = 406 nm = 4.06 * 10⁻⁷ m
speed of light is a constant = 3.0 * 10⁸ m/s
From the formula above, frequency = speed / wavelength
therefore, frequency = (3.0 * 10⁸ m/s) / 4.06 * 10⁻⁷ m
frequency = 7.39 * 10¹⁴ Hz
2. From the equation above, wavelength = speed/frequency
speed of radiation = 3.0 * 10⁸ m/s
frequency = 2.09 * 10⁹ Hz or 2.09 * 10⁹ s⁻¹
therefore, wavelength = (3.0 * 10⁸ m/s) / 2.09 * 10⁹ s⁻¹
wavelength = 1.44 * 10⁸ nm
