Is water a good solvent choice for recrystallization of NaCl?

Chemistry
1 answer:
nika2105 [10]3 years ago
7 0

Answer:

Water is not a good solvent choice.

Explanation:

While water is good solvent because of its polotiry. Water is not good for the recrystallization process becuase being a good recystallization solvent means that a compound must dissolves easily when the solvent is warm, but that is less soluble at room temperature or when cooled in an ice bath. Water has the dissolves when warm part down. But for the cooled part which is the most important it can not do.

How many pairs are shared between the nitrogen atoms for hydrazine
morpeh [17]
<span>A full outer shell has 8 valence electrons, and since each nitrogen has only five, they both need three more to get to a full outer shell. However, since they're the same atom, and they need the same amount of electrons, they're going to form a covalent bond, where they both SHARE three (if one gave three to the other, it would be down to two and even MORE unbalanced)</span>

Which statement is correct about the rate of most chemical reactions? It increases when the concentration of reactants decreases
stiv31 [10]

Answer:

It increases when the temperature increases.

Explanation:

  • According to Arrhenius relation: k = Ae(-Ea/RT).
  • The rate constant of the reaction and also the rate of the reaction increases exponentially with increasing the temperature of the reaction.
  • As the temperature increases, the no. of molecules that can posses the critical energy (activation energy) to initiate the chemical reaction and pass the energy barrier increases.

Allushta [10]
Low pH = high acidity.
HF has a very low pH, so when added to a solution, it will lower the pH of the solution and therefore make it more acidic. So the answer should be B.
