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.

Explanation:

4.                 limestone heat lime + carbon dioxide

The reactants in this expression above is limestone

The products of the reaction is carbon dioxide and lime

Reactant is the species that gives the product and it is usually found on the left hand side of the expression.

The product is the substance on the right hand side of the expression that forms through the experiment.

Heat is used to facilitate the reaction.

5. An exothermic reaction is a reaction in which heat is given off.

An endothermic reaction is a reaction in which heat is absorbed in the process.

An exothermic reaction is always warmer after the reaction whereas an endothermic reaction is colder at the end of the reaction.
