<span>Nitrogen trifluoride - NF3.
1 mol NF3 contains 1 mol atoms of Nitrogen
2.49 mol NF3 contains 2.49 mol atoms of Nitrogen
1 mol ---- 6.02 *10²³ atoms
2.49 mol ----- 2.49*6.02*10²³ = 15.0*10²³ atoms of N</span>

Rocks carried by the river smash together and break into smaller pieces. This process is called attrition.
Explanation:
- Rocks carried by the river smash together and break into smaller pieces. This process is called attrition.
- attrition is a form of coastal or river erosion, Attrition is an erosional process where rocks and pebbles are carried in the flow of a river.
- Abrasion occurs when the breaking waves which contain sand and larger pieces erode the shoreline or headland of the shore.
- When the rocks continue to collide with each other,they erode more and more, getting smaller and smaller until they are only sediment, this is when rocks that the sea is carrying
- The amount of attrition depends upon the number of factors: particle properties such as its size, shape, surface, hardness, and cracks.
- It also have environmental properties such as time, velocity, pressure, shear, and temperature.
D) All three bulbs would go out because the circuit would no longer have a ground thereby deeming it "open".
Answer:
Verdadero.
Explanation:
¡Hola!
En este caso, dado que las propiedades periódicas nos hablan de un comportamiento específico sobre los elementos en la tabla periódica, resulta primeramente necesario recordar que la electornegatividad nos dice que tan fuerte es un elemento para atraer electrones de valencia de otros elementos.
De este modo, inferimos que es verdadero, ya que de hecho la electronegatividad nos define el tipo de enlace, basado en la diferencia de electronegatividades de los elementos enlazados, de acuerdo con la imagen adjunta.
Saludos!
