Answer:
Sodium chloride has a crystalline face-centered cubic structure whereas metallic sodium body-centered cubic structure.
Explanation:
Hello, atomic arrangements provide the molecules different features and behaviors, since the sodium metal has a body-centered cubic structure (https://en.wikipedia.org/wiki/Cubic_crystal_system#/media/File:Cubic-body-centered.svg) the lack of inner atoms, allows the material to be soft and bendable. On the other hand the compacted sodium chloride's face-centered cubic structure (https://en.wikipedia.org/wiki/Cubic_crystal_system#/media/File:Cubic-face-centered.svg), provides it a crystalline structure which is hard and brittle since the atoms are closer.
Best regards!
According to the decomposition of XY is second order, and we assume that the rate constant (K) = 6.92 X 10^-3 M^-1 :
So according to this formula:
Kt= 1/[XY]t - 1/[XY]o
when [XY]o is the initial concentration = 0.1 m & [XY]t is the concentration after passing a period of time= 0.1 x 0.125 = 0.0125 m
and when K= 6.92X10^-3 M^-1
By substitution:
t = (1/[XY]t - 1/[XY]o) / K
=(1/0.0125 - 1/0.1) / 6.92X10^-3
∴t = 1011 S = 17 min
