Answer:
Explanation:
Hello!
In this case, since the applied current for the 50.0 mins provides the following charge to the system:
As 1 mole of electrons carries a charge of 1 faraday, or 96,485 coulombs, we can compute the moles of electrons involved during the reduction:
Then the reduction of Ga³⁺ to Ga involves the transference of three electrons, we are able to compute the moles and therefore the mass of deposited gallium:
Best regards!
Answer:
alot
Explanation:
because salt contains stuff
The correct answer is Aurora Borealis
A Van Allen Radiation Belt is a torus of energetic charged particles around the Earth, held in a place by Earth's magnetic field. The Van Allen belts are closely related to the popular aurora where particles strike the upper atmosphere and fluoresce.
Equations 2 and 4 are properly balanced
Answer:
ε = 201.5
Explanation:
Given data-
mass of benzene = 25.8 mg
= 25.8×10^-3 kg
Atomic mass of benzene= 78.11 amu
volume of hexane = 250.00 ml = 0.2500 L
Absorbance = 0.266
Length of the cell = 1.00 cm
Hence concentration =
solving we get
= 0.00132 M
Formula:
A= εcl
A= absorbance
c= concentration and l= length of cell
now substituting values in the above formula
0.266= ε×0.00132×1.000
⇒ε =
⇒ε = 201.5
