<h3>What do we know about the process of dissolution?</h3>

A solute can dissolve in a solvent in a solid, liquid, or gaseous phase to create a solution through the process of dissolution. Solubility. The greatest amount of a solute that may dissolve in a solvent at a particular temperature is known as its solubility. The solution is said to as saturated when the maximum amount of solute is present.

Several variables influence solubility, including:

  • The solute's concentration
  • The system's temperature
  • Pressure (for gases in solution)
  • The solvent's and solute's polarity

MaRussiya [10]

Answer:

2 NaI ---> 2 Na + I₂

Explanation:

The only way the reactant NaI can decompose is by separating into 2 atoms, Na and I. However, you must take into account that iodine (I) exists as a diatomic molecule.

An equation is balanced when there is an equal amount of each element on both sides of the reaction. These amounts can be modified by adding coefficients in from of the molecules/atoms.

The unbalanced equation:

NaI -----> Na + I₂

<u>Reactants</u>: 1 sodium, 1 iodine

<u>Products</u>: 1 sodium, 2 iodine

The balanced equation:

2 NaI ---> 2 Na + I₂

<u>Reactants</u>: 2 sodium, 2 iodine

<u>Products</u>: 2 sodium, 2 iodine
