Answer:
Explanation:
Hello,
In this case, since the reaction between potassium hydroxide and nitric acid is:
We can see a 1:1 mole ratio between the acid and base, therefore, for the titration analysis, we find the following equality at the equivalence point:
That in terms of molarities and volumes is:
Thus, solving the molarity of the base (KOH), we obtain:
Regards.
Kinetic energy is energy possessed by a body by virtue of its movement.
Potential energy is the energy possessed by a body by virtue of its position or state.
There are 6 electrons in the atom of a carbon.
The first atomic level will be occupied by 2 electrons while the second will be occupied by 4 electrons.
Based on this, the outer valence shell of carbon (which is L shell) will be occupied by 4 electrons.
Answer:
1s2 2s2 2p6 3s2 3p6 4s1
Explanation:
Aufbau's principal of the arrangement of electronic configuration states that, electrons fill orbitals of lower energy first before the higher energy. 1s2 2s2 2p6 3s2 3p6 4s2 3d10...
This arrangement explains the Aufbau's principal, hence, or therefore, the 1s2 2s2 2p6 3s2 3p6 4s1 is the right answer for the representation of the electron configuration for potassium (K).
