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.
The answer is •c•
Hope this is correct I tried
Hello there,
The rock reacted with the acid and made a new gaseous substance
Hope this helps.

The answer to your question would be _B High Temp
Answer:
Explanation:
At the cathode
In case of molten AgI
Silver will be collected
In case of molten LiI
lithium will be collected
in case of aqueous LiI,
hydrogen gas will be collected as reduction potential of H⁺ is more than Li⁺
in case of aqueous AgI,
Silver will be obtained at cathode because reduction potential of silver is more than H⁺
At the Anode
In case of molten NaBr
Bromine will be collected
In case of molten NaF
Fluorine will be collected
in case of aqueous NaBr ,
Bromine will be collected as reduction potential of Br⁻ is less than O⁻²
in case of aqueous NaF ,
oxygen will be obtained because reduction potential of F⁻ is more than O⁻² .
