See that 3 subscript on O in NaClO3 ? Hint to double the moles there.
2NaClO3 -> 2NaCl +3O2
The chemical formula NaClO₃ corresponds to sodium chlorate.
First, calculate the moles of each reactant. Next, determine which reactant is the limiting reactant by comparing the moles of each reactant to the stoichiometry of the balanced chemical equation. The reactant that produces the least amount of product based on stoichiometry is the limiting reactant.
