Aluminum hydroxide $\left(\mathrm{Al}(\mathrm{OH})_{3}\right)$ is often present in antacids to neutralize stomach acid (HCl). The reaction occurs as follows: $\mathrm{Al}(\mathrm{OH})_{3}(\mathrm{s})+3 \mathrm{HCl}(\mathrm{aq}) \rightarrow \mathrm{AlCl}_{3}(\mathrm{aq})+3 \mathrm{H}_{2} \mathrm{O}(1) .$ If 14.0 $\mathrm{g}$ of $\mathrm{Al}(\mathrm{OH})_{3}$ is present in an antacid tablet, determine the theoretical yield of AlCl_ produced when the tablet reacts with HCl.

Key Concepts

Balanced Chemical Equations

Balanced chemical equations depict the exact proportions in which reactants combine and products form, ensuring that mass and atoms are conserved. They are essential for determining the mole ratios between species, which is the first step in any stoichiometric calculation.

Stoichiometry

Stoichiometry is the calculation of the quantities of reactants and products in chemical reactions based on the balanced equation. It provides the relationships between the amounts, in moles, of different substances involved, allowing one to predict yields from given quantities.

Molar Mass and Mole Conversions

Molar mass is used to convert between the mass of a substance and the number of moles, which is critical in stoichiometric calculations. Understanding how to convert grams to moles and vice versa allows one to use the mole ratios from the balanced equation effectively.

Theoretical Yield

The theoretical yield is the calculated maximum amount of product that can be produced under ideal conditions from a given amount of reactant. It is determined using stoichiometric relationships and assumes complete conversion of the limiting reactant into products.
