Answer:
1.01 V
Explanation:
From Nernst equation;
Ecell= E°cell- 0.0592/n log Q
Where;
Ecell= observed emf of the cell
E°cell= standard emf of the cell
n= number of moles of electrons transferred
Q= reaction quotient
Q= [Ag^+]^3/[MnO4^-] [H^+]^4
Q= [0.01]^3/[1.20] [1.50]^4
Q= 1.65×10^-7
Ecell= 0.88 - 0.0592/3 log 1.65×10^-7
Ecell= 0.88 - [0.0197×(-6.78)]
Ecell= 0.88 + 0.134
Ecell= 1.01 V
Answer:
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers.
Explanation:
Answer:
0.98 M
Explanation:
Given data:
Mass of sugar = 20 g
Mass of water = 59 g
Concentration of solution = ?
Solution:
1 g = 0.01 L
59 g× 0.01 L/1 g
0.059 L
Concentration formula:
C = m/v
m = moles of solute
v = volume of solution
Number of moles of sugar:
Number of moles = mass/molar mass
Number of moles = 20 g/ 342.3 g/mol
Number of moles = 0.058 mol
Now we will calculate the concentration:
C = 0.058 mol/0.059 L
C = 0.98 mol/L
C = 0.98 M
