What is Law of Conservation of Matter?
The principle stating that matter is neither created nor destroyed in ordinary chemical reactions. The total mass of reactants equals the total mass of products. This law requires balanced chemical equations and is the basis of stoichiometry. Also called the law of conservation of mass.

The principle stating that matter is neither created nor destroyed in ordinary chemical reactions. The total mass of reactants equals the total mass of products. This law requires balanced chemical equations and is the basis of stoichiometry. Also called the law of conservation of mass.
The law of conservation of matter is the basis of all stoichiometric calculations, material balances in chemical engineering, gravimetric analysis, and the requirement for balanced chemical equations. Process material balances (mass-in = mass-out + accumulation) are fundamental to chemical plant des…
Mass balances are essential for chemical process safety: all toxic reactants and products must be accounted for in mass balance calculations. Unaccounted mass suggests undiscovered reaction pathways or leaks. Environmental permits require material balance accounting for all waste streams.
