  • Law of Conservation of Mass
    Principle stating that during a chemical reaction, the total amount of matter remains unchanged, only altering its form.
  • Antoine Lavoisier
    French chemist recognized for formulating the foundational principle that matter is neither created nor destroyed in reactions.
  • Chemical Reaction
    Process where substances interact to form new substances, with total mass remaining constant throughout.
  • Reactant
    Substance present before a chemical change, participating in the transformation to form new materials.
  • Product
    Substance resulting from a chemical transformation, formed from the rearrangement of initial materials.
  • Stoichiometry
    Area of chemistry focused on calculating the quantities of substances involved in chemical changes.
  • Solution Chemistry
    Branch of chemistry dealing with substances dissolved in liquids and their quantitative relationships.
  • Hydrogen
    Lightest element, often involved as a reactant in reactions forming water, symbolized as H2.
  • Oxygen
    Element essential for combustion and respiration, commonly reacts with hydrogen to produce water, symbolized as O2.
  • Water
    Compound formed from hydrogen and oxygen, represented as H2O, often the product in chemical reactions.
  • Mass
    Measure of the amount of matter in a substance, remaining unchanged before and after chemical changes.
  • Compound
    Substance composed of two or more elements chemically bonded, participating in chemical transformations.
