A solution containing 100 Ibm KN03/100 Ibm H20 at 80°C is fed to a cooling crystallizer operated at 25°C. Slurry from the crystallizer ( KN03 crystals suspended in saturated solution ) is fed to a filter, where the crystals are separated from the solution. Use the solubility data in Figure 6.5-1 to determine the production rate of crystals (Ibm/Ibm feed) and the solid-to-liquid mass ratio (Ibm crystals/Ibm liquid) in the slurry leaving the crystallizer.

Explanation:

i have same question

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.

if it's not useful, feel free to report for mistake in answer.

bcde is the incorrect answer it is a
