chemical reaction

    Cards (14)

    • Chemical reaction
      A process that leads to the chemical transformation of one set of chemical substance to another which occur in the surroundings and most likely almost in everything that exists
    • Reactants
      The substances that are converted to one or more different substances, the products
    • Products
      The different substances created from the rearrangement of the constituent atoms of the reactants
    • How chemical reactions occur
      1. Effective collision between reacting particles
      2. Orientation of particles favors creation/breaking of chemical bonds
      3. Reacting molecules possess minimum activation energy
    • The Law of Conservation of Mass states that mass is neither created nor destroyed in chemical reactions
    • Combination/Synthesis reaction
      A reaction in which two or more substances combine to form a single new substance
    • Reactants
      The materials in a chemical reaction that are found at the tail of the arrowhead
    • Products
      The materials in a chemical reaction that are found at the head of the arrowhead
    • Yield
      Symbolized by an arrow in a chemical reaction
    • A balanced equation conforms to the Law of Conservation of Mass
    • The number of atoms of each kind on the left side of the reaction must equal the number of atoms of each kind on the right side
    • Our bodies carry out chemical reactions to store the energy from food and spend that energy
    • Key chemical elements in the human body
      • Oxygen
      • Carbon
      • Hydrogen
      • Nitrogen
      • Calcium
      • Phosphorus
    • These key elements form the molecules (carbohydrates, lipids, nucleic acids, proteins) that make up our cells and carry out chemical processes needed for life
