9. **Write a Claim/Evidence/Reasoning response** to answer the question: What state of matter would you expect to find this substance (oxygen) in "the Goldilocks Zone"? Start with a claim that directly answers the question. Then, use the melting and boiling point data from the previous lesson as evidence and your models above to help with your reasoning. Your paragraph should have at least three sentences.
There are mainly three states of matter, such as solid, liquid, and gases. Element oxygen belongs to the p-block of the periodic table; Oxygen exists in the gas state. Oxygen boiling point is -183°C hence it easily exists in as gas states.
10. **Carbon Dioxide (CO₂):** Necessary for photosynthesis; helps regulate temperature of atmosphere
- **Lewis Diagram for C**
- **Lewis Diagram for O**
- **Lewis Model of CO₂**
Explain how the location of oxygen and carbon on the Periodic table explains why each atom of carbon bonds with two atoms of oxygen.

**Explanation of Diagrams:**
Although the diagrams themselves are not visible, typically:
- **Lewis Diagram for C (Carbon):** Displays four valence electrons around the carbon atom.
- **Lewis Diagram for O (Oxygen):** Displays six valence electrons around the oxygen atom.
- **Lewis Model of CO₂ (Carbon Dioxide):** Shows the central carbon atom double-bonded to two oxygen atoms, highlighting the sharing of electrons between the atoms.
These diagrams exemplify how atoms share electrons to form stable molecules, explaining the bonding nature and molecular geometry of carbon dioxide.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe1eb3209-ef50-4b39-ac07-da0ba9817959%2F5a5f6634-ab08-4aff-adca-ea8204bbeed1%2F8r2aef_processed.jpeg&w=3840&q=75)

The Lewis dot structures can be written according to the following steps:
The total number of electrons required for writing the structures is obtained by adding the valence electrons of the combining atoms.
For anions, add one electron for each negative charge and for cations, subtract one electron for each positive charge from the total number of valence electrons.
Distribute the total number of electrons as bonding shared pairs between the atoms in proportion to the total bonds.
Place the most electropositive atom at the central position in the molecule/ion.
After accounting for the shared pairs of electrons for single bonds, the remaining electron pairs are either utilized for multiple bonding or remain as the lone pairs.
All the atoms should satisfy octet rule in the Lewis structure
