<u>Answer and Explanation:</u>
Mercury combines with sulfur as follows -
Hg + S = HgS
Hg = 200,59
S = 32,066 Therefore 1.58 g of Hg will react with -
1.58 multiply with 32,066 divide by 200,96 of sulfur.
= 0.25211 g S
This will form 1.58 + 0.25211 g HgS = 1.83211 g HgS
The amount of S remaining = 1.10 - 0.25211 = 0.84789 g
Crystallization is the process of atoms forming a material with a crystal structure
The answer is 60 minutes to complete 50% of reaction.
Required moles of CH₃COONa.3H₂O = Molarity x Volume of solution in L
= 0.100 M x (100.0 mL)
= 0.100 M x 0.100 L
= 0.01 mol
Required mass of CH₃COONa.3H₂O = Required moles x Molar mass
= 0.01 mol x (136.08 g / mol) = 1.3608 g
The change in the internal energy of the system is -4511.8 J.
<h3>What is the change in the internal energy?</h3>
We know that according to the first law of thermodynamics, energy can neither be created nor destroyed but can be transformed from one form to the other.
Now we know that;
ΔE = q + w
ΔE = Change in internal energy
q = heat absorbed or evolved
w = work done
Now we have;
q = - 134.8 J (The system losses heat)
w = PdV
w = 5.73 (1.00 - 8.540)
w = -43.2 Latm or -4377 J
Then we have;
ΔE = - 134.8 J + (-4377 J)
ΔE = -4511.8 J
