of ethylamine value calculated by the student.
Explanation:
1.
The value of Aspirin solution = 2.62
Moles of s asprin =
Volume of the solution = 0.600 L
The initial concentration of Aspirin = c =
initially
c 0 0
At equilibrium
(c-x) x x
The expression of dissociation constant :
:
was the
value calculated by the student.
2.
The value of ethylamine = 11.87
The initial concentration of ethylamine = c = 0.100 M
initially
c 0 0
At equilibrium

of ethylamine value calculated by the student.
Answer:
Explanation:
Group 4A contains a total of 4 electrons for each atom in their valence shell. Filling the orbital diagram, let's say, for carbon, notice that when we start with period 2, we have two elements in the s-block, that is, lithium and beryllium. They correspond to the two s electrons that belong to the valence shell of carbon.
Moving on, we have boron and carbon, the remaining 2 electrons. Now, starting with boron, we're in the p-block.
That said, looking at the second period, the electron configuration for the valence shell of a group 4A element would be:
