Answer:
Which statement is true about the particles of a solid when the solid changes into a liquid? (5 points)
a. They stop vibrating.
Selected: b. Their kinetic energy increases. This answer is correct.
c. They move closer to each other.
d. The attractive force between them increases.
Explanation: when a solid turns to a liquid it means it was melted and it needs to be heated to melt meaning the kinetic energy increases because the solid was heated up. Also this was on my test and i got it right so yeah.
Answer:
11.54 M
Explanation:
In this case, all we have to do is to apply the following expression:
M = n/V
M: molarity
n: moles
V: volume of solution in liters
In this case, we can assume that the volume of water will be the volume of solution. This is because the problem is not specifing if the moles of AgNO3 are liquid or solid, so we can make a safe assumption of the volume.
Using the expression above we have:
M = 5.54 / 0.48
M = 11.54 M
This is the molarity of solution
Answer:
Titanium
Explanation:
BCC i.e. body-centered cubic is a type of non-primitive unit cell.
In bcc type crystal structure the atoms are arranged in the corners of the unit cell and also on the center of the body of that unit cell.
Among the given options Titanium is the only metal which does not form bcc type crystal structure.
Titanium forms hcp (hexagonal close packing ) type of crystal structure.
The coordination number of hcp is 12 and it is ABAB type lattice.
Answer:
I think that is called oxalic acid
Explanation:
Answer:
A !!
Explanation:
because the equator is basically all the weather , so it cant be d , c , or b because in the artic is not hot and the desert cant be cold . so the answer is A
