Interpretation:
Whether sulfur is a limiting reactant or not needs to be determined.
Concept introduction:
A chemical reaction involves the conversion of certain molecules (reactant) to new substance (product) by bond breaking and making. One of the reactants, which is present in limited amount and determines the amount of product is known as limiting reactant. Whereas another reactant is known as excess reactant.
