2 Na + Cl₂ → 2 NaCl
Here's why:
* Balancing the equation: The equation is balanced to ensure the same number of atoms of each element on both sides of the equation.
* States of matter: In this reaction, sodium is a solid (s), chlorine is a gas (g), and sodium chloride is a solid (s). We could include these in the equation, but it's not strictly necessary for a basic understanding.
Explanation:
* Two atoms of sodium react with one molecule of chlorine gas (which contains two chlorine atoms).
* This reaction forms two molecules of sodium chloride, each containing one sodium atom and one chlorine atom.
Important Note: This is a highly exothermic reaction, meaning it releases a significant amount of heat and light. It's a dangerous reaction to perform without proper safety precautions.
