    MATTER!!!

     

    Objectives for Unit 2 – Chemistry of Matter

     

    You will UNDERSTAND the following concepts…

    • Matter is made up of particles whose properties determine observable characterizes of matter and its reactivity.
    • Energy exists in many forms, and when these forms change, energy is conserved.

     

    You will KNOW the following ideas and concepts…

    • The motion of particles helps to explain the phases (states) of matter as well as changes from one phase to another.  
    • The phase in which matter exists depends on the attractive forces among its particles.
    • All matter is made up of atoms.  Atoms are the building blocks of living and nonliving matter.   Atoms are far too small to see with a light microscope.
    • Atoms and molecules are perpetually in motion.  The greater the temperature, the greater the motion.
    • Atoms may join together in well-defined molecules or may be arranged in regular geometric patterns.  
    • Interactions among atoms and or molecules result in chemical reactions.
    • The atoms of one element are different from the atoms of other elements.
    • There are more than 125 elements.  Elements combine in a multitude of ways to produce compounds that account for all living and nonliving substances.  Few elements are found in their pure form.
    • The Periodic Table is one useful model for classifying elements.  The periodic table can be used to predict properties of elements (metals, nonmetals, noble gases)
    • During a physical change, a substance keeps its chemical composition and properties.   Examples include freezing, melting, condensation, boiling, evaporation, tearing and crushing.
    • Mixtures are physical combinations of materials and can be separated by physical means.
    • During a chemical change, substances react in characteristic ways to form new substances with different physical and chemical properties.  Examples include burning of wood, cooking an egg, rusting of iron, and souring of milk.
    • The Law of Conservation of Mass states that during an ordinary chemical reaction, matter cannot be created or destroyed.  In chemical reactions, the total mass of the reactants equals the total mass of the products.
    • Solubility can be affected by the nature of the solute and solvent, temperature, and pressure.  The rate of solubility can be affected by the size of the particles, stirring, temperature and the amount of solute already dissolved.
