Answer: it’s carbon dioxide
Explanation:
This is it because decomposition takes place when carbonic acid breaks down So that’s why I put carbon dioxide
That’s so rude it equals the numbers
C, because Boiling doesnt change the substance, making it a Physical property
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.
