Nickel-Iron Battery In 1901 , Thomas Edison invented the nickel-iron battery. The following reaction takes place in the battery. \begin{equation} \mathrm{Fe}(\mathrm{s})+2 \mathrm{NiO}(\mathrm{OH})(\mathrm{s})+2 \mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \rightarrow \end{equation} \begin{equation} \quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\mathrm{Fe}(\mathrm{OH})_{2}(\mathrm{s})+2 \mathrm{Ni}(\mathrm{OH})_{2}(\mathrm{aq}) How many mol of $\mathrm{Fe}(\mathrm{OH})_{2}$ is produced when 5.00 $\mathrm{mol}$ of Fe and 8.00 $\mathrm{mol}$ of $\mathrm{NiO}(\mathrm{OH})$ react? \end{equation}

Key Concepts

Stoichiometry

Stoichiometry involves using the balanced chemical equation to determine the quantities of reactants and products. It provides the theoretical relationships between the amounts, measured in moles, of different substances that participate in a reaction.

Limiting Reactant

The limiting reactant is the substance that is completely consumed first in a chemical reaction, thereby determining the maximum amount of product that can be formed. Understanding which reactant limits the reaction is crucial for accurate yield calculations.

Molar Ratio

Molar ratios are derived from the coefficients in a balanced chemical equation and represent the proportional relationships between the moles of reactants and products. This ratio is essential for converting between amounts of different species in a chemical reaction.
