Answer: Crystallization is a technique which chemists use to purify solid compounds. Crystals often form in nature when liquids cool and start to harden. Certain molecules in the liquid gather together as they attempt to become stable. They do this in a uniform and repeating pattern that forms the crystal. The process is based on the principles of solubility: compounds (solutes) tend to be more soluble in hot liquids (solvents) than they are in cold liquids. If a saturated hot solution is allowed to <u>cool</u>, the solute is no longer soluble in the solvent and forms crystals of pure compound. Impurities are excluded from the growing crystals and the pure solid crystals can be separated from the dissolved impurities by filtration.
For an example the salt we get from seawater can have many impurities in it. Hence, the process of crystallization is in use to remove these impurities.

Answer:
D - Balance the equation
Explanation:
A balanced chemical equation shows the number of moles, volume, or mass of a compound/molecule that combines with another in order to give some certain products.
To quantitatively follow how reactants combine to form some desired products, one must express the equation in a balanced form so as to be able to carefully measure the amount of matter and the moles involved in a specific reaction. In chemistry, such calculation falls under stoichiometry (stoicheon means atom and metron is measurement).
