<span>The correct answer is b. Boiling point, why? because the liquid sample of napthalene is heated and remained at the temperature of 218 degrees celsius, the outcome was that the napthalene was completely vaporized, therefore we are given the scenario that at the temperature of 218 degrees celsius is considered to be the boiling pont of napthalene.</span>

Explanation:
If a material mixes readily with water it is describe as HYDROPHILIC. Hydrophilic substances are water loving molecules, there reaction with water is favorable in term of thermodynamics. This type of substance are usually charged and often have ability to get involve in hydrogen bonding.
Answer: 
Explanation:
Elevation in boiling point is given by:

= Elevation in boiling point
i= vant hoff factor = 3 (number of ions an electrolyte produce on complete dissociation)

= freezing point constant = 
m= molality

Weight of solvent (water)= 1.000 kg
Molar mass of solute
= 142 g/mol
Mass of solute
= 175.0 g


Thus the boiling point of water when 175.0 g of
, a strong electrolyte is dissolved in 1.000 Kg of water is 
Answer:An atom consists of three sub atomic particles which are protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge.
Explanation: because atoms are made up of particles
