Use the following reaction:
2Na + Cl2 2NaCl
If you start with 8 atoms of sodium and 6 molecules of chlorine, which one is the limiting reactant?
(Write the name of the element, not the symbol.)
The limiting reagent in a chemical reaction is the substance that is totally consumed when the chemical reaction is complete. The amount of product formed is limited by this reagent, since the reaction cannot continue without it.
Here chlorine gas (Cl2) is the limiting reactant
