Chrome The most important commercial ore of chromium is chromite $\left(\mathrm{FeCr}_{2} \mathrm{O}_{4}\right) .$ One of the steps in the process used to extract chromium from the ore is the reaction of chromite with coke (carbon) to produce ferrochrome (FeCr_ ). \begin{equation} 2 \mathrm{C}(\mathrm{s})+\mathrm{FeCr}_{2} \mathrm{O}_{4}(\mathrm{s}) \rightarrow \mathrm{FeCr}_{2}(\mathrm{s})+2 \mathrm{CO}_{2}(\mathrm{g}) \end{equation} What mole ratio would you use to convert from moles of chromite to moles of ferrochrome?

Key Concepts

Stoichiometry

Stoichiometry is the part of chemistry that deals with the calculation of the quantities of reactants and products in chemical reactions. It involves using the balanced chemical equation to determine the proportions in which substances react and are produced, ensuring that the law of conservation of mass is followed throughout the reaction.

Balanced Chemical Equations

A balanced chemical equation displays the amounts of reactants and products such that the number of atoms for each element is the same on both sides of the equation. This balance reflects the conservation of mass and provides the necessary coefficients that serve as conversion factors in stoichiometric calculations.

Mole Ratios

Mole ratios are the ratios between the amounts of reactants and products as indicated by the coefficients in a balanced chemical equation. These ratios allow for the conversion between moles of different substances involved in the reaction, facilitating the determination of how many moles of one substance are required or produced relative to another.
