Answer:
Hydrogen gas is evolved at the cathode and chlorine gas at the anode.
Explanation:
The solution will ionise. Hydrogen ions, H+, will migrate to the negative cathode ( where the current leaves the solution and chloride ions Cl- will migrate the the positive anode.
Answer:
819 K
Explanation:
Given data
- Initial pressure (P₁): 1 atm (standard pressure)
- Initial volume (V₁): 250 mL
- Initial temperature (T₁): 273.15 K (standard temperature)
- Final pressure (P₂): 0.500 atm
- Final volume (V₂): 1500 mL
- Final temperature (T₂): ?
We can find the final temperature using the combined gas law.
Answer: all other conditions equal, the rate evaporation of a contained liquid will be slower than the rate of evaporation of an uncontained liquid.
Justification:
1) The rate of evaporation increases as the surface area of the liquid (relative to the whole content) increases. This is, the greater the surface is the faster the evaporation.
2) That is so because the higher the surface of the liquid the more the number of particles in the liquid that are in contact with the surrounding air and so the more the particles will escape from the liquid to the air (which is what evaporation is).
3) A liquid contained will take the form of the container, so part of the liquid wil remain below the surface, while an uncontained liquid will spread all over the surface and so pratically all the liquid is in contact witht the air surrounding it.
Answer:
may have liability on the contracts he negotiates on behalf of the prospective corporation
Explanation:
Answer:
B
Explanation:
The tendency of a liquid to convert to vapour increases smoothly with increasing temperature. Vapour pressure shows the tendency of a liquid to convert to vapour. Increase In vapour pressure shows an increased tendency to convert to vapour. The higher the temperature, the higher the vapour pressure.
