Explanation:
A process in which water vapor changes into liquid state is known as condensation. As we know that when energy is released in a reaction then it is known as exothermic reaction and when energy is absorbed in a reaction then it is known as endothermic reaction.
As vapors have high energy so, when they change into liquid state then heat energy is released by them. Therefore, condensation is an exothermic reaction.
As per Le Chatelier's principle, any disturbance caused in an equilibrium reaction will tend to shift the equilibrium in a direction away from the disturbance.
So, when there will occur a decrease in temperature then molecules of a gas will come closer to each other. Hence, there will also occur a decrease in vapor pressure of the gas.
The answer is that all of them are correct.
Answer/Explanation:
No compounds must be made up of two or more elements. otherwise it wouldn't be a compound. There must be some type of combination or it isn't a compound.
Earth quake and volcanoes.
I hope i have answerd your question.
Your welcome.
Answer:
The pH at the equivalence point is 7.0.
Explanation:
This is because the solution only contains water and a salt that is neutral.
Since neither H+ or OH-, molecules remain in the solution.
We can conclude that the equivalence point is 7.0.
