<h2>Observation of purified crystals.</h2>

Explanation:

  • Recrystallization is the process in which a compound is dissolved in a hot solvent and then allowed to cool which forms the crystals.
  • It is a technique used for purification of solids.
  • Recrystallization mainly depends on the solubility of the solvent that means the solid should be soluble in the solvent when it is hot and should be insoluble in the same solvent when it is cool.
  • The observations while doing recrystallization is to observe the purified crystals obtained and to filter it out.

Explain how plate tectonics are responsible for where we find some of our natural resources.
Mekhanik [1.2K]
At divergent boundaries, plates separate, forming a narrow rift valley. Here, geysers spurt super-heated water, and magma, or molten rock, rises from the mantle and solidifies into basalt, forming new crust. Thus, at divergent boundaries, oceanic crust is created.

What is the molarity of solution prepared by dissolving 11.75 g of KNO3 in enough water to produce 2.00 L of solution?
zysi [14]
The molar mass of the compound potassium nitrate, KNO3 is equal to 101.1032 g/mol. Then, we determine the number of moles present in the given amount,
                       n = 11.75g / (101.1032 g/mol) = 0.116 mol
Then, molarity is calculated by dividing the number of moles by the volume of the solution. The answer is therefore 0.058 M.
