To balance the chemical equation [tex]\( C_5H_5 + Fe \rightarrow Fe(C_5H_5)_2 \)[/tex], first look at the number of each type of atom on both sides of the equation. You can see that there are 10 carbon (C) and 10 hydrogen (H) atoms on the product side but only 5 carbon and 5 hydrogen atoms on the reactant side. Therefore, you need 2 molecules of [tex]\( C_5H_5 \)[/tex] on the reactant side to balance the equation. Hence, the balanced equation is [tex]\( 2C_5H_5 + Fe \rightarrow Fe(C_5H_5)_2 \)[/tex]. This reaction is a type of synthesis reaction, as two or more reactants combine to form a single product.
