Dilution means adding more solvent to a solution to lower down its concentration and in that process volume of solution expands. That means on diluting a solution the following parameters will change:
1. Amount of solvent
2. Total volume of the solution
3.Concentration of the solution
So the parameter that does not change is the amount of solute that will remain constant on diluting a solution, So here the the answer will be the amount of solute that will remain unchanged during dilution.
What's the relationship between total and partial pressure? The total pressure is the sum of the parcial pressures!
So for us, it would be:
378= 212+101+x
where x is the parcial pressure of nitrogen.
Now we count:
378= 212+101+x
378=313+x
378-313=x
65=x
So the parcial pressure exerted by nitrogen is 65!

Explanation:
The first step in this reaction is a unimolecular reaction. It involves the formation of the carbocation. This is so because tertiary alkyl halides only undergo substitution by SN1 mechanism due to sterric crowding.
The second step in the reaction is bi molecular. In this step, the carbocation now combines with the OH^- to yield the alcohol.
Net equation of the reaction is;
(CH3)3CBr + OH^- -------> (CH3)3COH + Br^-
The intermediate here is the carbocation, (CH3)3C^+
Answer:
Alkenes are those organic compound which have double carbon bond
Formula of but-2-ene = C4H8
1. an alpha particle
gamma rays are formally massless, positrons and electrons (beta particles) have negligible mass, but alpha particles have about 4 amu of mass
