Answer:
Water has strong hydrogen bonds between molecules. These bonds require a lot of energy before they will break. This leads to water having a higher boiling point than if there were only weaker dipole-dipole forces. Water also has a high specific heat.
Explanation:
Hope this helped it is what I could find!
Molality is defined as the ratio of moles of solute to the mass of solvent in Kg. It is also known as molal concentration.
Formula used for determining the molality is:
(1)
where,
= change in temperature
= freezing point depression constant
m = molality
Here, = and =
Put the above values in formula (1)
=
Hence, molality of nonvolatile solute is
Answer:
Chromatography is a method by which a mixture is separated by distributing its components between two phases. The stationary phase remains fixed in place while the mobile phase carries the components of the mixture through the medium being used.
Have a great day! ^^
Most young children already have plenty of energy without the need for coffee to sustain them throughout the day, so at least until they are 12 years old, it's best to avoid giving your kids coffee if possible
