Balancing Chemical Equations | Representing Chemical …

Iron is a metal. When we represent it in a balanced chemical equation, we write only \(\text{Fe}\). Sulfur occurs as \(\text{S}_{8}\) but we write only the empirical formula: \(\text{S}\). We do this for all network structures. Writing formulae like this represents one unit of the compound or network structure.
