Answer:
Explanation:
A single electron has a charge of 1.60217733 × 10-19 Coulombs. A collection of 6.2415 × 1018 electrons has a charge of one Coulomb (1/1.60217733x10-19). 1.6 into 10 raise to power -19 no of electrons are present in one coulomb of charge.

has 6 electrons.
Answer: %C = 63.5%, %H = 6.00%, %N = 9.3%, %O = 21.2%
Hello!
Atoms are made of 3 types of particles: Electrons, protons, and neutrons. The protons and neutron (referred to collectively as nucleons) make up the nucleus (center) of the atom, while the electrons surround the nucleus.
Answer:
Protons, neutrons, and electrons.
Oxid # : 0 0 +2 -1
![equation:Cl_{2} + Ni -----\ \textgreater \ Ni^{2+} + 2Cl ^{-}](https://tex.z-dn.net/?f=equation%3ACl_%7B2%7D%20%20%2B%20%20Ni%20-----%5C%20%5Ctextgreater%20%5C%20%20%20Ni%5E%7B2%2B%7D%20%20%2B%20%202Cl%20%5E%7B-%7D)
∴ the nickel was oxidized while chlorine was reduced
nickel reduction potential = - 0.25 V
but since it is being oxidised the you have to switch the integer sign so the
the potential of nickel in this case becomes + 0.25 V
chlorine was reduced thus its reduction potential remains same = + 1.36 V
Overall Cell potential = ∑ of half cell potential
The overall cell potential = (+ 1.36) + (+ 0.25)
= + 1.61 V
∴
the answer would be D
