Answer:
A. Atoms gain, lose, or share electrons to achieve a full valence shell
Explanation:
The octet rule is best explained as the process in which atoms lose or gain or share electrons to achieve a full valence shell.
- In this process bonds are formed when there is an attraction between the two substances.
- For electrovalent compounds, an atom will lose electrons or gain electron to form an ion, the electrostatic attraction causes the bond formation.
- Covalent compounds, form by sharing of electrons.
Therefore, the octet rule is attained when atoms gain full valence configuration.
Answer:
Propenyl-benzene
Explanation:
Hello,
Elimination reaction of solid (1-chloropropyl)-benzene due to the heat in presence of ethanol turns out based on the attached picture in which both the chlorine a the hydrogen in the second carbon go out and subsequently get together to form propenyl-benzene and hydrochloric acid.
Best regards.
Answer:
8.6 mol
Explanation:
number of moles = molar concentration x volume in litre
number of moles = 2.33 M x 3.70 L = 8.6 mol
MgF2 + H2
Fluorine now has a subscript of 2 due to the fact that Magnesium has a charge of two; swap and drop rules applied means that it switches over to Fluorine.
Hydrogen has a charge of two as it's one of the diatomic elements, meaning it has a charge of two when alone. The other diatomic elements are Fluorine, Oxygen, Nitrogen, and the Halogens.
Hope this helps!
