Answer:
See explanation
Explanation:
If we look at the electron configuration closely, we will discover that the element must have had a ground state electron configuration of 2,4.
This is because, the innermost shell usually holds two electrons while the outer shells hold eight electrons each. The four electrons must be accommodated in the second shell in the ground state configuration of the compound.
However, when the atom is excited, one electron from this shell may move to the third shell to give the excited state configuration 2-3-1 as shown in the question.
The answer you are looking for is water.
Answer:
That is a compound. If it was an element it would either just be Na or Cl.
Answer:
The rate of reaction of a zero-order reaction is 0.0020 mol/L.
Explanation:
The rate expression of the zero order kinetic are :
![R=k[A]^o](https://tex.z-dn.net/?f=R%3Dk%5BA%5D%5Eo)
[A]= initial concentration of reactant
k = rate constant
R = rate of reaction
We have :
Rate constant of the reaction , k = 0.0020 mol/L s

R = 0.0020 mol/L s
The rate of reaction of a zero-order reaction is 0.0020 mol/L.
