Answer:
The answer to your question is: d
Explanation:
Electron configuration of Carbon.
Atomic number of carbon = 6
a) 1s²2s²2p¹ Number of electrons = 5, This is the electron configuration of Boron.
b) 1s²2s²2p⁴ Number of electrons = 8. This is the electron configuration of oxygen.
c) 1s²2s²p² Number of electrons = 6. This is the electron configuration of carbon. But I think is lacking a number two before p.
d) 1s²2s²2p² Number of electrons 6, This is the correct electron configuration of carbon.
First, we need to determine the half reaction of magnesium. It would be expressed as:
Mg2+ + 2e- = Mg
Given the mass of magnesium metal that is produced, we calculate the total charge of the electrolysis by the relations we can get from the half reaction. We do as follows:
4.50 kg Mg ( 1000 g / 1 kg ) ( 1 mol / 24.305 g ) ( 2 mol e- / 1 mol Mg ) ( 96500 C / 1 mol e- ) = 35733388.2 C
We are given the applied EMF in units of V. This value is equal to J/C. So, 5 V is equal to 5 J/C.
35733388.2 C (5 J/C) = 178666941 J
178666941 J ( 1 kW-h / 3.6x10^6 J ) = 49.63 kW-h
Answer: Pauli exclusion principle: only two electrons can occupy the same orbital and they must have opposite spin directions
