the students in ms. green's science class dissolved four salts in water. students varied water temperature to see if more or less salt would dissolve in a constant volume of water. changing the water temperature made little difference in the amount of dissolved in 100 grams of water.
a) kbr
b) kno
d) naclo3

C) NaCl

Explanation:

Its solubility is barely changing with temperature

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.
