The mass of reactants is equal to the mass of products.
The law that relates to the initial and final concentrations of reactants and products in a chemical reaction, as expressed in the equation c1v1 c2v2, is called the Law of Dilution.
The flow energy equation is a mathematical expression that describes the energy balance in a fluid flow system. It relates the energy input, output, and losses in the system. This equation helps us understand how energy is transferred and transformed within the system, highlighting the importance of energy conservation and efficiency in the flow process.
The Law of Conservation of Mass says that mass is neither created or destroyed. Think of mass as just being shifted from one place to the other. In a chemical equation, it has to get shifted evenly. Since a chemical equation is just that...an equation, it must be balanced/equal on each side. What ever elements are on the reactant side must, in some way, be equal to the elements on the product side. Even though you are sending the reactant elements through some type of chemical reaction (oxidation, combustion, etc) the product elements still have to come out evenly on their side of the equation. Otherwise, something would be created or destroyed and that's not possible according to LOCOM. Scientists use coefficients to balance out the elements based on total number of atoms of each element per side. H6 + O > 6H2O 7 atoms >18 atoms Unbalanced (would show that atoms were created and according to the LOCOM that's not possible.) 2H6 + 6O > 6H2O 18 atoms > 18 atoms Balanced (Adding coefficients on the Reactant side to balance the atoms allows this equation to meet the requirements of the LOCOM.)
Conservation of mass
The heat equation is derived from the principles of conservation of energy and Fourier's law of heat conduction. It describes how heat is transferred through a material over time. The equation is a partial differential equation that relates the rate of change of temperature to the second derivative of temperature with respect to space and time.
The energy loss equation states that the total energy input into a system is equal to the energy output plus any energy lost as heat or other forms. This equation relates to the conservation of energy principle, which states that energy cannot be created or destroyed, only transferred or transformed. By accounting for energy losses, we can ensure that the total energy in a system remains constant, in line with the conservation of energy principle.
The equation that shows conservation of both mass and charge is the continuity equation, ∂ρ/∂t + ∇⋅J = 0, where ρ is the charge density and J is the current density in an electromagnetic field. This equation states that the rate of change of charge density plus the divergence of the current density must equal zero, implying that charge is conserved locally. Additionally, in nuclear reactions, mass-energy equivalence (E=mc^2) relates the conservation of mass and energy.
Antoine Lavoisier's findings and studies on chemical reactions led to the formulation of the law of conservation of mass. He demonstrated that in a chemical reaction, the total mass of the reactants is equal to the total mass of the products, showing that matter is neither created nor destroyed in a chemical reaction. Lavoisier's work laid the foundation for modern chemistry and our understanding of the conservation of mass.

The first law of thermodynamics equation is: U Q - W. This equation states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system. This equation relates to the conservation of energy in a thermodynamic system because it shows that energy cannot be created or destroyed, only transferred between different forms (heat and work) within the system.
The equation that relates wavelength and frequency is: speed of light = wavelength x frequency. This equation shows that as the frequency of a wave increases, its wavelength decreases, and vice versa.
The equation that relates pressure, force, and area is: Pressure = Force / Area. This equation states that pressure is equal to the force applied per unit area.
