- Law of Conservation of Mass (Matter)
- Experiment to Verify the Law of Conservation of Mass
Antoine Lavoisier , a prominent French chemist, observed, in 1774, that the mass of reacting substances was the same as the mass of the product.
The law of conservation of mass (matter) states that in an ordinary chemical reaction, matter can neither be created nor destroyed. This means that in a chemical reaction, the total mass of all the reacting substances (i.e. the reactants) is equal to the total mass of the products.
Example 8.2.1:
Sodium chloride reacts with silver trioxonitrate(V) to produce silver chloride and sodium trioxonitrate(V). Na = 23, Cl = 35.5, Ag = 108, N = 14,
