Answer:
Pb(CH3COO)2(s) -------> Pb^2+(aq) + 2CH3COO^- (aq)
Explanation:
Recall that a strong electrolyte is an electrolyte that dissociates completely in solution. Hence, if we say that lead(II) acetate is a strong electrolyte we are actually saying that lead(II) acetate ,dissociates completely in solution to yield lead II ions and acetate ions.
This implies that the reaction equation shown in the answer section tends to go to completion since lead(II) acetate is a strong electrolyte.
I would but your picture is too dark!!!
Answer:
1. The temperature increases in the center of a nebula, and nuclei begin to fuse.
2. As the nuclear fusion sets off a chain reaction, the nebula gets hotter and brighter and turns into a star.
3. The star stays in the main sequence stage for a long time.
4. The star runs out of hydrogen and turns into a planetary nebula or a supernova, depending on its mass.
5. Heavy elements are created when the supernova explodes.
6. All that remains of the star now is the core. In some cases, the star turns into a black hole.
Explanation:
Answer:
T = 3.75 K
Explanation:
As we know
PV = nRT
R =8.3144598 J. mol-1. K-1
P = 0.562 atm
V = 83.3 mL
moles in 0.392 g of I2 = 0.392/mass of I2 = 0.392 grams/253.8089 g/mol = 0.0015 moles
Substituting the given values, we get
0.562 atm * 83.3 *10^-3 L = 0.0015 moles * 8.3144598 J. mol-1. K-1 * T
T = 3.75 K
