Answer:

\huge\boxed{\sf KCl_{(aq)}+Na_{(aq)} \longrightarrow K_{(l)}+NaCl_{(aq)}}

Explanation:

<u>Chemical formulas for every compound:</u>

Potassium vapor => K_{(l)

Molten soldium chloride => NaCl_{(aq)}

Molten Potassium chloride => KCl_{(aq)}

Molten Sodium Metal => Na_{(aq)}

<u>The reaction will be as follows:</u>

KCl_{(aq)}+Na_{(aq)} \longrightarrow K_{(l)}+NaCl_{(aq)}

This reaction is usually called displacement reaction in which an element displaces another element of a compund.

Kilauea volcano in Hawaii emits 200-300 tons of sulfur dioxide into the atmosphere each day. This is an example of

  • the impact of natural processes on the earth's environment.
  • air pollution from a natural source.
  • the magnitude of the chemistry associated with the environment.

Kilauea volcano in Hawaii emits noxious compounds of sulfur dioxide and other harmful pollutants as a result of a reaction with atmospheric water vapors and oxygen.

This reaction results in acid rain and volcanic smog which pollutes the air.

Over the years, the volcano has become a potential threat to health as harmful oxides are accelerating respiratory problems and acid rain destroys crops, and also harms water supplies.
