What is the edge length of a face-centered cubic unit cell that is made of of atoms, each with a radius of 154 pm
gladu [14]

Answer:

The edge length of a face-centered cubic unit cell is 435.6 pm.

Explanation:

In a face-centered cubic unit cell, each of the eight corners is occupied by one atom and each of the six faces is occupied by a single atom.

Hence, the number of atoms in an FCC unit cell is:

8*\frac{1}{8} + 6*\frac{1}{2} = 4 atoms

In a face-centered cubic unit cell, to find the edge length we need to use Pythagorean Theorem:

a^{2} + a^{2} = (4R)^{2}     (1)

Where:

a: is the edge length

R: is the radius of each atom = 154 pm      

By solving equation (1) for "a" we have:

a = 2R\sqrt{2} = 2*154 pm*\sqrt{2} = 435.6 pm    

Therefore, the edge length of a face-centered cubic unit cell is 435.6 pm.   

I hope it helps you!

A balloon is filled to a volume of 2.20L at a temperature of 22*C. The balloon is then heated to a temperature of 71*C. Find the
goldfiish [28.3K]

2.565L

Explanation:

  • Charles law states that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature.V/T=K

         V1/T1=V2/T2        

          Unit of Kelvin = 273.15

  • To get the absolute temperature, we need to convert the degree celsius temperature to kelvin.

          T1= 22+273.15= 295.15 K

          T2 = 71+273.15= 344.15 K

          V1 = 2.20 L

          V2 =?

          2.20/295.15=V2/344.15

          0.00745 x 344.15 = 2.565 L

Hence,  2.565 L is the new volume of the balloon.

Explain how lines latitude and longitude help people find locations on earth.
Bad White [126]
Latitude and longitude are the x and y axis on a grid. When you're trying to find a location on earth, you need to graph it, so you can pinpoint the location. There is no grid if there is no longitude and/or latitude lines. Without one of the lines, it would be very hard to graph, which will be difficult in finding locations on earth. But hey, I'm not too sure. I recommend looking at other people's answers too and searching it up.
