Answer:
r = 1.45 Å
Explanation:
given,
λ = 1.436 Å
θ = 20.62°
d = a
n = 2
metal gold crystallizes in a face centered cubic unit cell
Radius of the gold atom = ?
using Bragg's Law
n λ = 2 d sin θ
2 x 1.436 Å = 2 a sin 20.62°
a = 4.077 Å
We know relation of radius for face centered cubic unit cell
r = 1.45 Å
the radius of a(n) gold atom. is equal to 1.45 Å
Answer:
ooh thanks but don't give me advise
Answer:
To use them in future projects and saving the community.
Explanation:
An explanation about using them in future projects is that you can, for example, use plastic for a biology project. It's also a proven fact that recycling can help the environment so there will be less pollution due to having certain recyclables in the wrong places such as the ocean.
An object with volume greater than it mass. to account less density and thus it will float
