Stoichiometric Calculations MCQ - Practice Questions with Answers

Stoichiometry:

Stoichiometry deals with the calculation of masses (sometimes volumes also) of the reactants and the products involved in a chemical reaction. Before understanding how to calculate the amounts of reactants required or the products produced in a chemical reaction, let us study what information is available from the balanced chemical equation of a given reaction.

Stoichiometric Calculations:

Step 1 Write down the correct formulas of reactants and products.

Step 2 Balance the number of atoms both side reactant and product.

Step 3 Make the equation balanced.

The coefficients of atoms or molecules are stoichiometric coefficients.

Limiting Reagent:

The reactant which consumed first into the reaction When we are dealing with the balanced chemical equation then if the number of moles of reactants are not in the ratio of the stoichiometric coefficient of the balanced chemical equation, then there should be one reactant which should be limiting reactant.
