Match the following aqueous solutions with the appropriate letter from the column on the right.1. 0.19 m AgNO3 2. 0.17 m CrSO4 3. 0.13 m Mn(NO3)2 4. 0.31 m Sucrose(nonelectrolyte) A. Highest boiling pointB. Second highest boiling pointC. Third highest boiling point D. Lowest boiling point

0.13 m of → Highest boiling point

0.19 m of → Second  Highest boiling point

0.17 m of → Third highest boiling point

0.31 m Sucrose (nonelectrolyte)  → Lowest boiling point

Explanation:

Elevation in boiling is given by :

Where :

i = van't Hoff factor

= Molal Elevation constant of solvent

m = molaity of the solution

1) 0.19 m of

i = 2 (electrolyte)

Molality of the solution = 0.19

Elevation is boiling point of solution:

2) 0.17 m of

i = 2 (electrolyte)

Molality of the solution = 0.17

Elevation is boiling point solution :

3) 0.13 m of

i = 3 (electrolyte)

Molality of the solution = 0.13

Elevation is boiling point solution :

4) 0.31 m Sucrose (nonelectrolyte)

i = 1 ( non electrolyte)

Molality of the solution = 0.31 m

Elevation is boiling point solution :

Higher the value of elevation in temperature higher will be the boiling point of the solution .

The decreasing order of solution from highest boiling point to lowest boiling point is :

0.13 m of → Highest boiling point

0.19 m of → Second  Highest boiling point

0.17 m of → Third highest boiling point

0.31 m Sucrose (nonelectrolyte)  → Lowest boiling point

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.
