Table salt has a solubility of 36 g of salt in 100 g of water at 40 celsius. if 15 g of salt is added to 50 g of water at the same temperature, is the resulting solution saturated or unsaturated? explain your answer.

the resulting solution will be unsaturated

Explanation:

A saturated solution is a solution that contains just as much solute as it can normally hold at a particular temperature. An unsaturated solution contains less solutes than the amount required to saturate the solution. A solubility of 36g per 100g of water means that 36g of the salt dissolves completely in 100g of water. It also means that 18g of the salt will normally dissolve in 50g of water. Hence 15g of the salt in 50g of water is an unsaturated solution.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
