Discover the fundamentals of chemical reactions and the relationship between reactants and products. Learn how compounds and elements transform during reactions following the Law of Conservation of Mass. Explore real-life examples and delve into the balance of mass in a reaction.
E N D
Reactants vs. Products • compounds/elements on the right; they are “produced” compounds/elements on the left; they are “reacting”
Law of Conservation of Mass • Stated by Lavoisier in the 18th century • Total mass of substances in a chemical reaction does not change • Ex: C6H12O6 + 6O2 6CO2 + 6H2O 180g glucose + 192g oxygen 264g carbon dioxide + 108g water 372g material before 372g material after amount input = amount output
