Explanation:
Ka is the acid dissociation constant. pKa is simply the -log of this constant.
Mathematically;
pKa = - log Ka
Ka = 10^-pKa
a. acid a has a pka of 6.0 what is its ka?
Ka = 10^-6 = 10⁻⁶
b. acid b has a pka of 8.60 whats its ka?
Ka = 10^-8.6 = 2.51e⁻⁹
c. acid c has a pka of -2.0 whats its ka?
Ka = 10^-(-2) = 10^2 = 100
Answer: D. 4,6,4
Explanation:
The valence electron is the electron found in the outermost shell of an atom, and participates in bond formation.
For the following element, the valence electron can be noticed when we write the electronic configuration of each element.
Silicon = 1s2 2s2 2P6 3s2 3p2
Sulphur = 1s2 2s2 2P6 3s2 3p4
Germanium = 1s2 2s2 2P6 3s2 3p6 3d10 4s2 4p2
