A balanced chemical equation
The purpose to balance a chemical equation is for mass conservation. The total mass of reactants should be equal to the total mass of products. In another words, the number of atoms for each individual atoms should remain constant. To consider the following chemical equation: 4Fe(s) + 3O2(g) —> 2Fe2O3(s) The symbols in brackets represent…
