Answer:
Crystal structure; brittleness
Step-by-step explanation:
The image illustrates the crystal structure of an ionic solid.
This structure affects the brittleness of the solid.
If you strike a sharp blow to the crystal with a hammer, the crystal layers will slide past each other.
The ions with the same charge will repel each other, and the crystal will fly apart.
Answer:
-32821.2 J (negative sign implies that work is done by the system)
Explanation:
The expression for the calculation of work done is shown below as:
Where, P is the pressure
is the change in volume
From the question,
= 18.0 - 1.00 L = 18.0 L
P = 18.0 atm
Also, 1 atmL = 101.3 J
So,
(negative sign implies that work is done by the system)
