Answer:
6.2g of sugar solution contains 72.5g
C. 5670 mL
1 liter is 1000 ml so 5.67 * 1000 is 5670
Answer:
Equilibrium Constant = (3.60 × 10⁶²)
Explanation:
The change in Gibb's free energy for a galvanic cell is given as
Δ = -nFE°
where n = number of electrons transferred = 5 for this reaction
F = Faraday's constant = 96500 C
E° = cell potential = +0.74 V
But the change in Gibb's free energy for galvanic cell reaction is also given as
ΔG = -RT In K
R = molar gas constant = 8.314 J/mol.K
T = absolute temperature in Kelvin = 25 + 273.15 = 298.15 K
K = Equilibrium constant.
Equating these two expressions
-nFE° = - RT In K
RT In K = nFE°
In K = (nFE°) ÷ (RT)
In K = (5 × 96500 × 0.74) ÷ (8.314 × 298.15)
In K = 144.04
K = e^(144.04)
K = (3.60 × 10⁶²)
Hope this Helps!!!
Answer:
Percent Yield = 91.97%
Explanation:
Aluminum hydroxide Formula: Al(OH)3 Molar mass: 78 g/mol
Stomach acid Formula: HCl Molar mass: 36.46 g/mol
Aluminum Chloride Formula: AlCl₃ Molar mass: 133.34 g/mol
14g Al(OH)3
2Al(OH)3 + Cl2 → 2Al(OH)3Cl
Balanced equation
14/156 = 0.0897 Moles of Al(OH)3
Ratio is 2:1:2 so same ratio for Al(OH)3 to AlCl₃
0.0897 x 266.68 = 23.92grams of AlCl₃
Theoretical yield of aluminum chloride
Actual yield aluminum chloride 22.0 g
Percent yield?
Percent Yield = (actual Yield/Theoretical yield) x 100
Percent Yield = (22/23.92) x 100
Percent Yield = 91.97%
Answer: The nitronium ion is a strong electrophile
Explanation:
The detailed mechanism of the reaction is shown in the images attached. The flow of electrons has been shown with arrows. HNO3 is first protonated by H2SO4 this protonated specie H2NO3+ now forms H2O and NO2+.
