Answers:
A catalyst is a substance that changes the rate of the reaction, and is not consumed in the reaction!
A solution is a uniform mixture of molecules or ions of one substance in another!
A solute is the substance dissolved in a solution!
A solution is the substance that does the dissolving in a solution!
Have a BEAUTIFUL day~
Force /Area = Pressure
Force = Pressure * Area
Force = 1065 * 17 = 18105 N
weight = 18105 N
I hope this helps!
Answer : The percentage aniline protonated is, 0.0209 %
Explanation :
First we have to calculate the pOH.

Now we have to calculate the hydroxide ion concentration.
![pOH=-\log [OH^-]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%20%5BOH%5E-%5D)
![5.68=-\log [OH^-]](https://tex.z-dn.net/?f=5.68%3D-%5Clog%20%5BOH%5E-%5D)
![[OH^-]=2.09\times 10^{-6}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D2.09%5Ctimes%2010%5E%7B-6%7DM)
The equilibrium chemical reaction will be:

From the reaction we conclude that,
Concentration of
ion = Concentration of
ion = 
Now we have to calculate the percentage aniline protonated.


Thus, the percentage aniline protonated is, 0.0209 %
Answer:
C) a low heat of vaporization.
Explanation:
It is C) a low heat of vaporization.
Low heat of vaporization means less amount of energy is required to vaporize a liquid. This further means the liquid has weaker intermolecular force of attraction that is why on provide lesser heat only it vaporizes.
Low vapor pressure, high boiling point and high critical temp. all contribute to strong intermolecular forces in a liquid
The fragrant organic compounds found in many flowers that contain a carbonyl group bonded to a carbon atom and a hydrogen atom are called aldehydes.
