Yasmin's teacher tells her that the solubility of salt is 360 g/l at room temperature (25 °c). how can yasmin make an unsaturated salt solution?

By adding less amount or quantity of the salt (solute), than the medium (solvent) can dissolve at a particular temperature that is to make an unsaturated solution at room temperature, Yasmin should add less than 360 g of salt to one liter of the solvent

Explanation:

An unsaturated solution is one that consists of less than the maximum mass or quantity of the solute that it is capable of dissolving.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
