Enter the appropriate symbol for an isotope of potassium-39 corresponding to the isotope notation AZX.
muminat
The notation is actually written in this way (shown in the attached picture). The X is the symbol of the element. So, for potassium, the symbol is K. The A represents the mass number of the isotope. In this case, that would be equal to 39. The Z represents the atomic number of potassium, which is 19. Therefore, the symbol for the isotope is:  ³⁹₁₉K

A block of material has a volume of 50 cubic centimeters, and a mass of 1,000 grams; what is that object's density?
zhannawk [14.2K]

Answer:

Density = 20\ g/cm^3

Explanation:

Given that,

Mass of the object, m = 1000 g

Volume of the block, V = 50 cm³

We need to find the density of the object. Density is equal to mass per unit volume.

d = m/V

d=\dfrac{1000\ g}{50\ cm^3}\\\\=20\ g/cm^3

So, the density of the object is 20\ g/cm^3.

Someone please answer the question attached.
nikdorinn [45]

Answer:

Option ( 1 )

Explanation:

This atom has a cub close pack structure, and therefore - the number of edge center present in X atoms =  4,

Number of unit cells present in X atoms = 6

____________________________________________________

Now the 6th coordination number of X atom = 6 * 4 = 24,

So respectively, the 3rd coordination number of X = 8 -

And thus the ratio between the 6th coordination number and the 3rd coordination number = 24 / 8 = 3,

Option ( 1 )

<u><em>Hope that helps!</em></u>
