Capitolo 4, Problema 45
Iron(III) oxide reacts with carbon monoxide according to the equation: Fe2O3(s) + 3 CO(g) → 2 Fe(s) + 3 CO2(g) A reaction mixture initially contains 22.55 g Fe2O3 and 14.78 g CO. Once the reaction has occurred as completely as possible, what mass (in g) of the excess reactant remains?
Guida verificata passo dopo passo1
Calculate the molar mass of Fe_2O_3 and CO using the periodic table.
Convert the given masses of Fe_2O_3 and CO to moles by dividing by their respective molar masses.
Determine the limiting reactant by comparing the mole ratio of Fe_2O_3 to CO from the balanced equation with the mole ratio from the initial amounts.
Use the stoichiometry of the reaction to calculate how much of the excess reactant is consumed by the limiting reactant.
Subtract the moles of the excess reactant consumed from the initial moles to find the remaining moles, then convert this back to grams using the molar mass.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Stoichiometry
Stoichiometry is the calculation of reactants and products in chemical reactions based on the balanced chemical equation. It allows us to determine the proportions of substances involved in a reaction, which is essential for identifying limiting and excess reactants. In this case, stoichiometry will help us calculate how much of each reactant is consumed and how much remains after the reaction.

Stoichiometry Concept
Limiting Reactant
The limiting reactant is the substance that is completely consumed first in a chemical reaction, thus determining the maximum amount of product that can be formed. Identifying the limiting reactant is crucial for calculating the amounts of products and any excess reactants left over. In this reaction, we will need to find out which reactant, Fe2O3 or CO, limits the formation of iron and carbon dioxide.

Excess Reactant
The excess reactant is the substance that remains after the reaction has gone to completion, as it is not completely consumed. Understanding the concept of excess reactants is important for calculating how much of a reactant is left over after the reaction. In this scenario, once we identify the limiting reactant, we can determine the mass of the excess reactant that remains unreacted.
