<u>Answer:</u> The order of increasing boiling points follows:

<u>Explanation:</u>
The expression of elevation in boiling point is given as:

where,
= Elevation in boiling point
i = Van't Hoff factor
= change in boiling point
= boiling point constant
m = molality
For the given options:
- <u>Option 1:</u> 0.12 m

Value of i = 1 (for non-electrolytes)
So, molal concentration will be = 
- <u>Option 2:</u> 0.02 m LiBr
Value of i = 2
So, molal concentration will be = 
- <u>Option 3:</u> 0.05 m

Value of i = 3
So, molal concentration will be = 
As, the molal concentration of
is the highest, so its boiling point will be the highest.
Hence, the order of increasing boiling points follows:

Answer:
Dalton's theory are based on the two laws that are: Law of conservation of mass and law of constant composition. This theory basically described their properties of atoms.
This theory state that all the atoms are made up of matter which are invisible and in the elements all the atoms are identical in mass and properties.
Answer:
Explanation:
Energy is absorbed to break bonds. Bond-breaking is an endothermic process. Energy is released when new bonds form. Bond-making is an exothermic process.
