During the recrystallization of a solid, the sample is dissolved in hot solvent then filtered while hot. The filtrate is allowed

to cool and the mixture is filtered a second time. What effect will result if the filtrate solution is cooled too rapidly? Small impure crystals will form. Small pure crystals will form. The maximum amount of the compound as a purified solid will be obtained. Large impure crystals will form.

Answer:

<em>If the filtrate solution is cooled too rapidly, Small pure crystals will form.</em>

Explanation:

The crystals form by two processes, nucleation and particle growth. Thus the size of the crystals is determined by the predominance between one or the other. In order to obtain the lower number of nucleus  and the larger crystals it is necessary to cool the solution slowly. If the solution  is cooled too rapidly there is no time to the particles growth and the result will be small crystals. But also, a fast cooling avoid the impurities in the crystals.

All molecules are made of similar type of atom true or false​
vichka [17]

Answer:

False

Explanation:

Not all molecules are compounds, since some molecules, such as oxygen gas (above image of molecule of-O2) or ozone (O3), consist only of one element or type of atom. Water is also a molecule because it is made from atoms that have been chemically combined.

2.3 x 10²¹ particles H = __________ mol H (round to the nearest thousandth)
Natalka [10]

Taking into account the definition of avogadro's number, 3.82×10⁻³ moles of H are 2.3×10²¹ particles of H.

<h3>Avogadro's Number</h3>

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

<h3>This case</h3>

Then you can apply the following rule of three: if 6.023×10²³ particles are contained in 1 mole of H, then 2.3×10²¹ particles are contained in how many moles of H?

amount of moles of H= (2.3×10²¹ particles × 1 mole)÷ 6.023×10²³ particles

<u><em>amount of moles of H= 3.82×10⁻³ moles</em></u>

Finally, 3.82×10⁻³ moles of H are 2.3×10²¹ particles of H.
