Answer:
AL*3+ + 3e- =AL.
(10A×1930)÷96500=0.2mole e-
0.2÷3×27=1.8g(AL)
The energy would increase
b) increase kinetic energy
Answer:
Concentration of unknown solution is 0.0416 M
Explanation:
As we know
Absorbance is equal to the product of molar absorptivity of KMnO4 m, path length and concentration
From the given set of graphical data, it is clear that the absorbance vs concentration is a straight line.
From the graph, we can obtain-
Y = 5.73 X – 0.0065
Absorbance = 0.232
0.232 = 5.73 X – 0.0065
X = 0.0416
Concentration of unknown solution is 0.0416 M
Decomposition, because the oil eventually breaks down bc of bacterias and evaporate into the ocean!
