First figure out how many atoms you have with Avogadro's number. Since there are 63.5 grams/mol and you have 50.6 grams, you have (50.6/63.5)6.022E23=4.7986E23 atoms. Since there are 29 protons per atom, there are also 29 electrons per atom, so you should have a total of
29*4.7986E23=1.3916E25 electrons.
Since there is a positive charge you know some of these electrons are missing. How many are missing can be found by dividing the charge you have by the charge on the electron: 1.6E-6/1.6022E-19 = 9.98627E12 electrons are missing.
Now take the ratio of what is missing to what there should be:
9.98627E12/1.3916E25 = 7.1760873E-13

Explanation:La ecuación de Van der Waals es una ecuación de estado de un fluido compuesto de partículas con un tamaño no despreciable y con fuerzas intermoleculares, como las fuerzas de Van der Waals. La ecuación, cuyo origen se remonta a 1873, debe su nombre a Johannes van der Waals, quien recibió el premio Nobel en 1910 por su trabajo en la ecuación de estado para gases y líquidos, la cual está basada en una modificación de la ley de los gases ideales para que se aproxime de manera más precisa al comportamiento de los gases reales al tener en cuenta su tamaño no nulo y la atracción entre sus partículas.
Answer:
Green part of the visible spectrum.
X ray part of the electromagnetic spectrum.
Infrared part of the electromagnetic spectrum.
Explanation:
Wien's displacement law
Where, b = Wien's displacement constant = 2.898×10⁻³ mK
T = Temperature in kelvin
So, the wavelength would be of around the green part of the visible spectrum.
So, the wavelength would be of around the X ray part of the electromagnetic spectrum.
Human body temperature = 37°C = 37+273.15 = 310.15 K
So, the wavelength would be of around the Infrared part of the electromagnetic spectrum.
