Which of the following you do NOT need to pay attention while using a centrifuge?
Phoenix [80]

Answer:

The radius of the centrifuge.

Explanation:

Hello,

Since the radius of the centrifuge is just a design parameter, it wouldn't be a cause of failure because it is used to know how many tubes could be fitted in into the centrifuge. On the other hand, keeping you attention away from other factors could turn into a failure as long as the sample could be poured down or just turn out inadequate for the expected results.

Best regards.

Explain how the development of the atomic theory is an example of science's self-correcting process of discovery in depth.
Stolb23 [73]

Answer:

En química y física, la teoría atómica es una teoría científica sobre la naturaleza de la materia que sostiene que está compuesta de unidades discretas llamadas átomos. Empezó como concepto filosófico en la Antigua Grecia y logró ampliar aceptación científica a principios del siglo XIX cuando los descubrimientos en el campo de la química demostraron que la materia realmente se comportaba como si estuviese hecha de átomos.

La palabra átomo proviene del adjetivo en griego antiguo átomos, que significa «indivisible». Los químicos del siglo XIX empezaron a utilizar el término en relación con el número creciente de elementos químicos irreducibles.1​ Cerca del cambio al siguiente siglo, a través de varios experimentos con electromagnetismo y radiactividad, los físicos descubrieron que los "átomos indivisibles" eran de hecho un conglomerado de varias partículas subatómicas (principalmente, electrones, protones y neutrones), las que pueden existir separadas unas de otras. De hecho, en ciertos entornos extremos, como las estrellas de neutrones, la presión y la temperatura extremas impiden que los átomos puedan existir en absoluto.

Ya que se descubrió que los átomos podían dividirse, los físicos inventaron el término «partículas elementales» para describir las partes "indivisibles", aunque no indestructibles, de un átomo. El campo de ciencia que estudia las partículas subatómicas es la física de partículas y es en este campo donde los físicos esperan descubrir la auténtica naturaleza fundamental de la materia

The element of group 1 hour reactive but those of group 18 are inert, why?​
Bogdan [553]

Answer:

The noble gases (Group 18) are located in the far right of the periodic table and were previously referred to as the "inert gases" due to the fact that their filled valence shells (octets) make them extremely nonreactive.
