. Which chemical equation best illustrates the Law of Conservation of Mass?. . 2H2O = H2 + O2. . CH4 + 3O2 = CO2 + 2H2O. . Al4C3 + 3H2O = CH4 + 4Al(OH)3. . Zn + 2HCl = ZnCl2 + H2 . . Could you help explain?

The best equation which illustrate the law of conservation of mass is

Zn +2 HCl --> ZnCl2 + H2

This is because the mass of the product is equal to the mass of reactant. for example the mass of Zn is 1 in the reactant and product side. According to the law of mass conversation the mass in a isolated system is neither created nor destroyed by chemical reaction or physical transformation
