Baking soda (NaHCO $_{3}$ ) can be made in large quantities by the following reaction: $\mathrm{NaCl}(a q)+\mathrm{NH}_{3}(a q)+\mathrm{CO}_{2}(a q)+\mathrm{H}_{2} \mathrm{O}(\ell) \rightarrow$.$$\mathrm{NaHCO}_{3}(s)+\mathrm{NH}_{4} \mathrm{Cl}(a q)$$ If $10.0 \mathrm{g}$ of $\mathrm{NaCl}$ reacts with excesses of the other reactants and $4.2 \mathrm{g}$ of $\mathrm{NaHCO}_{3}$ is isolated, what is the percent yield of the reaction?

$\mathrm{NaCl}(a q)+\mathrm{NH}_{3}(a q)+\mathrm{CO}_{2}(a q)+\mathrm{H}_{2} \mathrm{O}(\ell) \rightarrow$.$$\mathrm{NaHCO}_{3}(s)+\mathrm{NH}_{4} \mathrm{Cl}(a q)$$
If $10.0 \mathrm{g}$ of $\mathrm{NaCl}$ reacts with excesses of the other reactants and $4.2 \mathrm{g}$ of $\mathrm{NaHCO}_{3}$ is isolated, what is the percent yield of the reaction?

Key Concepts

Stoichiometry

Stoichiometry involves using the balanced chemical equation to relate the amounts of reactants and products in a reaction. It provides the basis to calculate how many moles of product can form from a given number of moles of a reactant.

Mole-to-Mass Conversion

Mole-to-mass conversion is used to translate between the mass of a substance and the number of moles based on its molar mass. This is an essential step in quantifying reactants and products for stoichiometric calculations.

Theoretical Yield

The theoretical yield is the maximum amount of product that can be produced from a given amount of reactant, as predicted by stoichiometry. It assumes that the reaction goes to completion and there are no losses or side reactions.

Limiting Reactant

The limiting reactant is the substance that is completely consumed first in a chemical reaction, thus limiting the amount of product that can be formed. Identifying the limiting reactant is crucial to accurately calculate the theoretical yield.

Percent Yield

Percent yield is calculated by dividing the actual yield obtained experimentally by the theoretical yield, then multiplying by 100. It measures the efficiency of a reaction, indicating how much of the expected product was actually formed.
