Answer:
I do K12 and c is correct!
Answer:- Van't hoff factor(i) for the unknown ionic compound is 2.77.
Solution:- Elevation in boiling point is a colligative property and the equation used for solving this type of problems is...
delta Tb = i x m x kb
where delt Tb is elevation in boiling point.
i is Von't hoff factor.
m is molality of the solution and kb is the molal elevation constant. It's value for water is 0.512.
Boiling point of solution is given as 103.4 degree C and we know that water boils at 100 degree C.
So, delta Tb = 103.4 - 100 = 3.4 degree C
molality is given as 2.4m.
Let's plug in the values...
3.4 = i x 2.4 x 0.512
i = 3.4/(2.4 x 0.512)
i = 2.77

- Amine functional group
It would be conduction since you car is made out of metal and almost everything in it is too so when you touch its very hot like it got conducted heat
