Answer:

The temperature remains

Explanation:

The temperature of a boiling substance remains the same because the extra energy is used in phase transition, that is to break the bonds between the molecules that hold them close together in the liquid state. With increased energy the molecules gain enough kinetic energy to overcome inter-molecular   forces and change state from liquid to gas

What is the hypothetical van't Hoff factor of magnesium nitrate, Mg(NO3)2?
vovangra [49]

Answer:

The hypothetical van't Hoff factor of magnesium nitrate,Mg(NO_3)_2 is <u>3 .</u>

Explanation:

Lets calculate -

Mg(NO_3)_2\rightarrow Mg^2^+ +2NO_3^-

We know that ,

i=\alpha n+(1-\alpha )

Dissociation should be 100% for the hypothetical vant hoff factor , that is

\alpha =1 and n=3 for  Mg(NO_3)_2

Therefore , putting the given values ,

i=1\times3+(1-1 )

i=3+0

i=3

<u>Hence , the answer is 3.</u>
