If you were to perform a recrystallization experiment and wanted to form very large crystals of pure substance, what would be the most UNfavorable conditions

The question is incomplete, the complete question is;

If you were to perform a recrystallization experiment and wanted to form very large crystals of pure substance, what would be the most UNfavorable conditions?

A. Fast cooling solution, use of an anti-solvent, rapidly evaporating solution

B. Slowly cooling solution, slowly evaporating solvent

Fast cooling solution, use of an anti-solvent, rapidly evaporating solution

Explanation:

Recrystallization is a process of obtaining pure crystals from solution. The procedure involves dissolving the crystals in a solution in which they are soluble at high temperature but insoluble at low temperature.

As the solution cools, the pure crystals are obtained from the solution.

The solvent to be used must be a slow cooling, slow evaporating solvent so that the crystals can be efficiently recovered from solution.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
