Answer:
C. The concentration of the copper sulfate is too low
Explanation:
If you decrease the pressure of a fixed amount of gas, its volume will increase.
Answer:
B) 
Explanation:
The electric force between charges can be determined by;
F = 
Where: F is the force, k is the Coulomb's constant,
is the value of the first charge,
is the value of the second charge, r is the distance between the centers of the charges.
Let the original charge be represented by q, so that;
= 2q
= 
So that,
F = 
x 
= 2q x
x 
=
x 
=
x 
F =
x 
The electric force between the given charges would change by
.
The answer is inertia becuase it means nothing happening or is doing nothing
