However, this means that in most situations the law of conservation of mass can be assumed valid. This law was first formulated by Antoine Lavoisier in 1789, but Mikhail Lomonosov in 1748 had also expressed similar ideas earlier. It was the key to making chemistry into a real science instead...
The law of conservation of mass states that the total mass of a system remains constant during a chemical reaction or physical change. In other words, the mass of the products in a chemical reaction must equal the mass of the reactants. This law is a fundamental principle in c...
The conservation of mass equation may be rewritten in differential form. The term representing the surface integral may be transformed into a volume integral by means of Gauss's divergence theorem: (2.9)∫V[∂ρ∂t+div(ρv→)]dV=0 Since the limit of integration is arbitrary, and ρ and...
Origin of mass may be linked to recently discovered Higgs bosons. Matter conservation means conservation of baryonic number A and leptonic number L, A and L being algebraic numbers. Positive A and L are associated to matter particles, negative A and L are associated to antimatter particles. All...
