Question

Predict the product in the combination reaction below (not necessarily balanced).

___Na (s) + ____Cl2 (g) → __________

Answer 1

The product in the combination reaction Na (s) + Cl2 (g) is NaCl (s).

Step-by-step explanation:

In the combination reaction Na (s) + Cl2 (g) the product is NaCl (s).

When sodium reacts with chlorine gas, 2 sodium atoms combine with 1 chlorine molecule to form 2 sodium chloride compounds. The balanced equation for this reaction is 2Na (s) + Cl2 (g) → 2NaCl (s).

It is important to note that chlorine exists as a diatomic molecule (Cl2) in nature, and that is why 2 chlorine atoms are required in the reactants and products.
