In our instance, we assumed that each sodium (Na) and chlorine (Cl2) had been in extra. Nevertheless, if sodium (Na) had been the limiting reagent, the response would produce much less sodium chloride (NaCl).
The limiting reagent will be recognized by calculating the variety of moles of every reactant. The substance with the smallest variety of moles is the limiting reagent.
For instance, if the variety of moles of sodium (Na) is 4.35 mol and the variety of moles of chlorine (Cl2) is 0.85 mol, sodium (Na) is the limiting reagent.
To find out the limiting reagent, we have to calculate the variety of moles of every reactant. The substance with the smallest variety of moles is the limiting reagent.
