Answer:
See explanation
Explanation:
Crystallization is a separation technique used to obtain pure crystals of a substance from an impure mixture of solid substances.
The impure solid is dissolved in an appropriate hot solvent. This hot solvent is able to effectively dissolve the solid. However, as the solution is allowed to cool, the pure solid separates out of the solution as crystals.
The solid is now filtered to obtain the pure solid. The solid is also washed and dried to remove any solvent contaminant.
Answer:
E
C eg In graphites and diamonds
A salt would be left over. For example, if you reacted NaOH with HCl, your products would be NaCl, a salt, and water.
FCH₂CH₂F will form Intermolecular Hydrogen bond
FCH₂CH₂F has H-F atoms linked together by Hydrogen bond whereas in HOCH₂CH₂OH here, carbon is linked with oxygen and oxygen is again linked with Hydrogen.
<h3>What is Intermolecular Hydrogen bond ?</h3>
Intermolecular hydrogen bonding refers to the formation of hydrogen bonds between molecules of the same or distinct substances. As an illustration, consider hydrogen bonds in water, alcohol, ammonia, etc.
- An illustration. (i) hydrogen connection between the hydrogen fluoride molecules. (ii) The hydrogen bond in molecules of alcohol or water
- Atoms within a molecule are held together by intramolecular forces. There are forces between molecules known as intermolecular forces.
