Final answer:
The given chemical equation 2Na + Cl2 -> 2NaCl represents a possible chemical reaction.
Step-by-step explanation:
The given chemical equation 2Na + Cl2 → 2NaCl represents a possible chemical reaction. It shows the combination of two sodium atoms (Na) with one molecule of chlorine gas (Cl2) to form two molecules of sodium chloride (NaCl). The equation is balanced, indicating that the same number of atoms of each element is present on both sides of the reaction arrow.
