STEP 1
1. We need to identify which row best completes the two statements provided.
2. The first statement relates to the three-dimensional shape of molecules.
3. The second statement relates to the transition of molecules from liquid to gas.
STEP 2
1. Analyze the first statement and identify the correct explanation.
2. Analyze the second statement and identify the correct explanation.
3. Match both explanations to the correct row in the table.
STEP 3
Analyze the first statement: "The idea that best explains why molecules have shapes in 3 dimensions is..."
- The shape of molecules in three dimensions is often explained by the VSEPR (Valence Shell Electron Pair Repulsion) theory, which states that electron pairs around a central atom will arrange themselves to minimize repulsion. This leads to the conclusion that "repulsion from electrons causes the bonds to spread out."
STEP 4
Analyze the second statement: "Atoms and molecules are able to move from the liquid to the gas state when..."
- The transition from liquid to gas occurs when the kinetic energy of the molecules is sufficient to overcome the attractive forces between them. Therefore, the correct explanation is "the kinetic energy of the molecules overcomes the attractive forces."
STEP 5
Match both explanations to the correct row in the table:
- The first explanation corresponds to "repulsion from electrons causes the bonds to spread out."
- The second explanation corresponds to "the kinetic energy of the molecules overcomes the attractive forces."
- These explanations are found in the first row.
The statements are best completed by the information in row:
