In the chemical reaction below, sodium would be considered a 2Na + Cl2 --> 2 NaCl O catalyst O intermediate product restant

Reactant

Explanation:

The chemical expression is given as:

             2Na        +       Cl₂     →   2NaCl

The species on the left hand side which are Na and Cl₂ are referred to as the reactants.

The specie on the right hand side, NaCl is the product of the reaction.

There is no catalyst shown in this reaction.

Such a reaction as this is called a combination reaction or synthesis reaction in which two reactants gives rise to a product.
