<h3>
Answer:</h3>
TRUE- The surface tension of CH3Br is greater than the surface tension of CH3Cl.
FALSE-Water forms spherical drops on wax because the surface tension of water is greater than the adhesive forces between wax and water.
<h3>
Explanation:</h3>
- The statement that, the surface tension of CH3Br is greater than the surface tension of CH3Cl is true.
- This is because of the fact that CH₃Br has more molar mass compared to CH₃Cl. Additionally, CH₃Br has greater dispersion forces and is more polarizable thus having greater surface tension compared to CH₃Cl.
- The statement that "Water forms spherical drops on wax because the surface tension of water is greater than the adhesive forces between wax and water" is FALSE.
- We would correct it by saying, Water forms spherical drops on wax because the cohesive force of water is greater than the adhesive forces between wax and water.
- Cohesive forces are forces of attraction between molecules or particles of the same type while adhesive forces is a force of attraction between molecules of different type.
Answer: Lower frequency
Explanation:
Frequency is the space in between two parts of a wave
Draw CO2, C in the middle and O on each side. O has 6 e- and C has 4, so 6+6+4= 14 e-.
