Answer:
I did the same thing I hope this helps you and sorry if its incorrect :)
When observing the photo above, I see that in both scenes, the bottom glass has 8 as their molecule energy and the top has 16 as their molecule energy. Since the bottom glass has more molecules in scene 2, that means they have more total energy. However, in scene 1, the top glass has more total energy. In scene one, the top is warmer and the bottom is cooler. In scene 2, the bottom glass is warmer than the top. No pieces are at the same temperature. When they have been touching for a while, the pieces will be at the same temperature since they will eventually reach equilibrium. The temperature will compare because at the start, they were different temperatures. However, after they will have the same temperature.
b2+ + 2 NO3- + 2 Na+ + 2 I- >> PbI2 (s) + 2 Na+ + 2 NO3-
net ionic
Pb2+ + 2 I- >> PbI2
Ksp = [Pb2+] [I-]^2
Ksp = 7.1 x 10^-9
molar solubility
let x = mol/L of Pb2+ that dissolve . This will give x mol/L Pb2+ and 2x mol/L I-
7.1 x 10^-9 = (x) (2x)^2 = 4x^3
molar solubility = 0.0012 M

Yes, with an increase of energy the particles will start to move faster
Answer:
The chemical symbol will be "
".
Explanation:
The given values are:
Current,
I = 2.50 amps
Time,
t = 2 hr
or,
= 7200 sec
Metal deposited,
W = 5.93 gm
As we know,
⇒ 
or,
⇒ 
On putting the given values, we get
⇒ 
⇒ 
hence,
⇒ 
⇒ 
⇒ 
Thus the above is the right answer.
