Answer:
A jump occurs when a core electron is removed.
Explanation:
A jump in ionization energy occurs when a core electron is removed. A large jump in the ionization energy easily be seen from the electronic configuration of an element.
For Beryllium, the electronic configuration of is 1s2 2s2.
There are two valence electrons in the outermost shell hence the ionization energy data for beryllium will show a sudden jump or increase in going from the second to the third ionization energy owing to the removal of a core electron
The electronic configuration for Nitrogen is 1s2 2s2 2p3. Five valence electrons are found in the outermost shell so the ionization energy data for nitrogen will show a sudden jump or increase in going from the fifth to sixth ionization energy because of the removal of a core electron
The electronic configuration of oxygen is 1s2 2s2 2p4. There are six valence electrons hence ionization energy for oxygen atom will show a sudden jump or increase in going from the sixth to the seventh ionization energy because of the removal of a core electron
The electronic configuration of Lithium is 1s2 2s1
There is one valence electron in its outermost shell so its ionization energy data will show a sudden jump or increase in going from the first to the second ionization energy because of the removal of a core electron.
C(C₆H₈O₇) = 0,47 M = 0,47 mol/L.
If we have one liter of solution:
V(solution) = 1 L.
n(solution) = 0,47 mol.
According to molecular formula of compound this can be citric acid.
Citric acid dissociation in water: C₆H₈O₇ → C₆H₅O₇³⁻ + 3H⁺.
There is four ions from one citric acid. Molarity is than c = 4 · 0,47 M = 1,88 M.
One mole of CuSO4 contains one mole of Cu2+.
One mole of any substance contains Avogadro's number of ions.
Therefore, number of ions of Cu2+ can be calculated as follows:
number of ions = number of moles * Avogadro's number
number of ions = 1 * 6.02 * 10^23 = 6.02 * 10^23 ions
Answer:
Cyclothymic Disorder
Explanation:
Cyclothymic disorder is a rare type of mood disorder whose symptoms resemble that of bipolar disorder. Although, the symptoms are manifested in a milder manner when compared with those of bipolar disorder.
The mood shifts in cyclothymic disorder are not as extreme as with Bipolar disorder.
The normal moods in cyclothymic disorder can last for a longer time than in bipolar disorder.
Although, the mood swings in cyclothymic disorder are more frequent than in bipolar disorder.
The true causes of cyclothymic disorder are not specifically known but bipolar disorder & cyclothymic can both occur in the same family suggesting that they may share similar causes.
Answer:
E. Cool a solvent below room temperature
Explanation:
When a solution that has had more solute dissolved at a higher temperature is now cooled, it becomes supersaturated at the lower temperature. Because that supersaturated solution holds more solute than is stable at the lower temperature, crystals start to form.
