Does sugar affect the boiling point of water

Adding sugar to boiling water it will increase the boiling temperature very slightly

What is the molality of .630g of NaCl dissolved in 525g of water

0.630 g NaCl x (1 mol NaCl/58.44 g NaCl) = 0.0108 mol NaCl

525 g H2O x (1 kg/1000g) = 0.525 kg H2O

0.0108 mol NaCl/0.525 kg H2O = 0.0206 molality

How can parts of a solution be separated by chromatography

The solution is absorbed onto a piece of paper

How can a solvent be separated from a solute by distillation

The solvent is collected as it is boiled off.

What effect does adding a solute have on the boiling point of a solution

Adding a solute to a solution, or some liquid, causes the boiling point to increase.

Think about water, sometimes people throw salt in their water when they're boiling noodles. This causes the boiling point to increase so the water is actually at a higher temperature (although most of the time the amount of salt added isn't nearly enough to cause any measurable change).

Which intermolecular force would affect the boiling point the least

Van der Waals forces

A concentration unit expressed in units of moles of solute per kilogram of solvent

This is called molality.

Which molecular solid would have the highest melting point

A solid that has hydrogen bonding would melt the easiest.

What is a homogeneous mixture equivalent to

A homogeneous mixture has only one phase.

What will result from increasing the temperature of gas

Increasing the temperature of gas the volume increase.

What is the molality of a solution that has 4 mol of KCl in 0.800 kg of water A.

The molality is 5.

Which of the following is an electrolyte solution

The answer is "Ions in water" on Apex
