When balancing chemical equations, what is typically conserved?

In chemical reactions, the law of conservation of mass plays a crucial role, stating that mass cannot be created or destroyed in a closed system. This means that when a chemical equation is balanced, the total mass of the reactants must equal the total mass of the products. Every atom present in the reactants is accounted for in the products, ensuring that the same number of each type of atom appears on both sides of the equation. This fundamental principle is why mass is conserved when balancing chemical equations.

The conservation of energy, while also important in the context of chemistry, refers to the total energy of a closed system remaining constant, but it does not directly pertain to the balancing of chemical equations. Volume is not necessarily conserved in all reactions, especially in gas reactions where the number of moles can change, and color is a property of substances that can change during a reaction but is not a conserved quantity. Therefore, mass is the correct choice for what is typically conserved when balancing chemical equations.
