Answer: C) 0.637 V
Explanation:
The balanced redox reaction is:
Here Zn undergoes oxidation by loss of electrons, thus act as anode. Lead undergoes reduction by gain of electrons and thus act as cathode.
Where both
are standard reduction potentials.
= -0.763
= -0.126
The standard emf of a cell is 0.637 V
Answer:

Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value
Given, Wavelength = 188 μm
Also, 1 μm =
nm
So,
Wavelength =
m
Thus, Frequency is:

I think by writing electronic configuration.
Answer is D breaking apart I to not more than two
Answer:
1.14 M
Explanation:
grams/molar mass = ans. / volume
317/110.98=2.86/2.50=1.14 M
