Answer:
in lewis structure, a solid line is usually used to represent a bond between the atoms
Explanation:
the dots that are shown around the atom represent the valence electrons on the outer shell
when there are multiple atoms, either a pair of dots circled (one dot from each atom) or a solid line is used to show the bonds between those atoms
Propene is the unsaturated compound.
Explanation:
In the presence of sulphuric acid (H₂SO₄), propanol will eliminate one water molecule (H₂O) to form propene, which is the unsaturated compound.

Answer:
the rising and falling of the surface of the ocean caused twice daily by the attraction of the sun and the moon
Explanation:
Answer:
Filled below
Explanation:
#v.e means number of valence electrons.
Also, the column total v.e is gotten by adding the v.e of the metal to the v.e of the non metal based on the chemical formula of both of the 2 elements combined.
K: Cl: 5; KCl; 1 + 5 = 6
Be: S: 6; BeS; 2 + 6 = 8
Na: F: 7; NaF; 1 + 7 = 8
Mg: Se: MgSe; 2 + 6 = 8
Al; N; AlN; 1 + 5 = 6
Be; F; BeF2; 2 + 2(7) = 16
Mg; N; Mg3N2; 3(2) + 2(7) = 20
Nitrogen gained 4 electrons.
Because Nitrogen's redox number went from +6 to +2, it must have gained 4 electrons (-4) in order to achieve this number. Thus, Nitrogen is reduced.
