Answer:
Option D. A law describing the behavior of condensed gases
Explanation:
Ideal gas law describes the behavior of gas molecules when the pressure is applied on it.
Ideal gas law states that the product of the volume and the pressure of molecule of an ideal gas is equal to the product of the temperature of the gas and the universal gas constant.
The equation of ideal gas law is given below.
PV = nRT
Answer:
MgSo4 : 7H2O
Mr 120 : Mr 126
mass 80: x
then cross multiply
Explanation:
making x the subject of the formula then you will get 84 as the mass of water
In growth you can see a change. In developing it takes time.
The chemist envision reaction take place when molecules/atoms collide with respect to the correct amount of energy and in the correct position so that the bond can be formed.These means that the reaction take place when two or more molecules collides and a reaction occurs.
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 %
