balanced chemical equation:
2 Na + Cl₂ → 2 NaCl
Explanation:
We have the following chemical reaction:
Na (s) + Cl₂ (g) → NaCl (s)
where:
(s) - solid
(g) - gas
To balance the equation the number and type of atoms entering the reaction have to be equal to the number and type of atoms leaving the reaction.
2 Na (s) + Cl₂ (g) → 2 NaCl (s)
2 Na atoms are entering the reaction 2 Na atoms are leaving the reaction
2 Cl atoms are entering the reaction 2 Cl atoms are leaving the reaction
