Hey there :
Correct answer is :
(a) CH₃CH₂CO₂H
From the given choices, acetic acid CH₃CH₂CO₂H is the strongest acid
I hope this will help !
The molecular weight of methane (CH4) is 16.04 g / mol.
Therefore:
22.8 grams x (mol) / 16.04 g =
(Grams unit cancel out)
1.42 mol
Answer:
A solution with a pH of 2
Explanation:
The lower a pH is in a liquid, the more acidic it is. 7 is the neutral pH for a liquid. We usually drink around that pH for water. A pH higher than 7 expresses that the liquid is a base.
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.
