See explanation and image attached
Explanation:
The mechanism for both the hydroboration of 2-methyl-1-pentene and acid-catalyzed hydration are shown i the image attached to this answer.
The both processes involve addition reaction. Hydroboration is similar to hydration but the orientation of addition is anti - Markovnikov in nature.
The acid-catalyzed hydration of 2-methyl-1-pentene yields a minor product and a major product. The major product is an accordance with Markovnikov rule as shown by the reaction mechanism. The minor product is anti - Markovnikov.
Answer:
ΔG = 98.67 kJ/mol
Explanation:
Let' s consider the following reaction.
Hg₂Cl₂(s) → Hg₂²⁺(aq) + 2Cl⁻(aq)
The standard Gibbs free energy (ΔG°) for the reaction is:
ΔG° = 1 mol × ΔG°f(Hg₂²⁺(aq)) + 2 mol × ΔG°f(Cl⁻(aq)) - 1 mol × ΔG°f(Hg₂Cl₂(s))
where,
ΔG°f: standard Gibbs free energy of formation
ΔG° = 1 mol × (154.72 kJ/mol) + 2 mol × (-134.08 kJ/mol) - 1 mol × (-215.06 kJ/mol)
ΔG° = 101.62 kJ
This is standard Gibbs free energy change per mole of reaction.
The Gibbs free energy of the reaction (ΔG) can be calculated using the following expression.
ΔG = ΔG° - R.T.lnQ
where,
R: ideal gas constant
T: absolute temperature
Q: reaction quotient
ΔG = ΔG° - R.T.ln([Hg₂²⁺].[Cl⁻]²)
ΔG = 101.62 kJ/mol + (8.314 × 10⁻³ kJ/mol.K) . (298.2 K) . ln [(0.926).(0.573)²]
ΔG = 98.67 kJ/mol

Answer:
27.9 g
Explanation:
CsF + XeF₆ → CsXeF₇
First we <u>convert 73.1 g of cesium xenon heptafluoride (CsXeF₇) into moles</u>, using its<em> molar mass</em>:
- Molar mass of CsXeF₇ = 397.193 g/mol
- 73.1 g CsXeF₇ ÷ 397.193 g/mol = 0.184 mol CsXeF₇
As <em>1 mol of cesium fluoride (CsF) produces 1 mol of CsXeF₇</em>, in order to produce 0.184 moles of CsXeF₇ we would need 0.184 moles of CsF.
Now we <u>convert 0.184 moles of CsF to moles</u>, using the <em>molar mass of CsF</em>:
- Molar mass of CsF = 151.9 g/mol
- 0.184 mol * 151.9 g/mol = 27.9 g
We know, change in temperature is given by :
Putting all given values, we get :
Hence, this is the required solution.
