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>

You are on the Titanic and want to find something that will float because you didn't
damaskus [11]

Find volume of pillow

L=78cm

B=55cm

H=25cm

\\ \bull\tt\longrightarrow V=LBH

\\ \bull\tt\longrightarrow V=25(78)(55)

\\ \bull\tt\longrightarrow V=107250cm^3

\\ \bull\tt\longrightarrow V=10.72m^3

Now

Mass=5.5kg

\\ \bull\tt\longrightarrow Density=\dfrac{Mass}{Volume}

\\ \bull\tt\longrightarrow Density=\dfrac{5.5}{10.72}

\\ \bull\tt\longrightarrow Density=0.5kg/m^3

Density of water=1000kg/m^3

As it is less than density of water it will float on water

Why atomic mass is an average vàlue​
lukranit [14]

Answer:

The atomic mass is the average number of protons and neutrons for all natural isotopes of an element. It is a decimal number.

Explanation:

Atomic Mass and Mass Number Example :

Hydrogen has three natural isotopes: 1H, 2H, and 3H. Each isotope has a different mass number.

1H has 1 proton. Its mass number is 1. 2H has 1 proton and 1 neutron. Its mass number is 2. 3H has 1 proton and 2 neutrons. Its mass number is 3. 99.98% of all hydrogen is 1H 0.018% of all hydrogen is 2H 0.002% of all hydrogen is 3H Together, they give a value of atomic mass of hydrogen equal to 1.0079 g/mol.
