Interpretation: for the given reaction, the diagram representing the amounts of reactants and products left after the reaction is to be identified from the given diagrams options.
- Balanced chemical equation of a reaction is written according to law of conservation of mass.
- Limiting reactant: limiting reactant is a reactant, which consumes completely in the chemical reaction. The quantity of the product depends on this limiting reactant, it can be determined with the help of balanced chemical equation for the reaction.
- Excess reactant: is the reactant, which remains unreacted after the completion of a reaction.
