The given question is incomplete. The complete question is as follows.
A certain liquid has a normal boiling point of 
and a boiling point elevation constant 
. A solution is prepared by dissolving some sodium chloride (NaCl) in 6.50 g of X. This solution boils at 
. Calculate the mass of NaCl that was dissolved. Round your answer to significant digits.
Explanation:
As per the colligative property, the elevation in boiling point will be as follows.
T = boiling point of the solution =
= boiling point of the pure solvent =
= elevation of boiling constant = 
We will calculate the molality as follows.
molality = 
i = vant hoff's factor
As NaCl is soluble in water and dissociates into sodium and chlorine ions so i = 2.
Putting the given values into the above formula as follows.
m = 100 g
Therefore, we can conclude that 100 g of NaCl was dissolved.
The tendency of an element to loose an electron and gain positive charge is called metallic character. So an element which easily looses its electron/electrons are called metals. Hope it helps
<span>all the ones that phase down are exothermic - freezing, deposition, condensation.
all the ones that phase up are endothermic - melting, sublimation, vaporization
endothermic is to gain heat, exothermic is to release heat</span>
The addition or removal of heat can cause phase transition like freezing water to ice or melting ice to water or the operation water to vapor condensation vapor to water simulation ice to vapor and the depsition vapor to ice
