Which of the following is not a key feature in writing balanced chemical equations?Group of answer choicesBalanced electronic charge on reactant and product sidesPhysical state of the reactants and productsBalanced number of atoms of the reactants and productsMasses of reactants and products
Solution
The option that is not a key feature in writing balanced chemical equations is "Masses of reactants and products". While the mass is conserved in a chemical reaction, it is not typically represented in a balanced chemical equation. Instead, balanced chemical equations ensure that the number of atoms for each element is conserved (balanced number of atoms of the reactants and products), the overall charge is conserved (balanced electronic charge on reactant and product sides), and often include the physical state of the reactants and products.
