IIT/JEE Chemistry Practice #4: Limiting Reagents

Dave explains a problem involving limiting reagents. The task is to determine the maximum moles of barium phosphate formed when 0.5 moles of barium chloride react with 0.2 moles of sodium phosphate. The video covers writing and balancing the chemical equation, identifying the limiting reagent, and performing stoichiometric calculations. Sodium phosphate is identified as the limiting reagent, and the maximum yield of barium phosphate is calculated to be 0.1 moles.
