GCSE Chemistry - What is a Limiting Reactant? Limiting/Excess Reactants Explained #27

The video tutorial explains the concept of limiting reactants in chemical reactions, using the example of hydrochloric acid reacting with calcium carbonate. It highlights the importance of identifying the limiting reactant to determine the amount of product formed. The tutorial also covers how to calculate the mass of a product, such as sodium oxide, by using stoichiometry and balanced chemical equations.
