CHEMICAL PROPERTIES
Characteristics that are observed ONLY when a substance ___________________ into a
________________________ substance


Types of Chemical Properties:
      1. Combustible/flammable: able to _________________
             -all chemicals come with a label that identifies their level of flammability
             -______________________ & __________________ are very flammable gases
             -carbon dioxide is ___________ a very flammable gas


      2. Reactivity: how easily a substance ______________ with another substance
             -many chemicals react with ____________ or _____________
             -all chemicals come with a label that identifies their level of reactivity
             -_________________: slow reaction & wearing away of metals (rusting,
             tarnishing)


PHYSICAL PROPERTIES
Characteristics that can be observed _____________________ changing the substance
into something else


Types of Physical Properties:
      color, _______, odor, taste, hardness, ___________, boiling, melting, & freezing points


      1. Luster: ___________________ or ___________________
             - most _______________ are shiny
             -diamonds have a lot of luster
             -many minerals are _______________


      2. Brittleness: how easily a substance _________________ into pieces
             - very brittle substances may _____________ or __________ with very little force
             - many rocks & minerals are brittle
             -_______________ is brittle because it crumbles easily
    3. Malleable: can be pounded into _______________
           - ______________________ is very malleable
           -clay is also malleable
           -substances that are malleable are usually _________ very brittle


    4. Ductile: can be pulled out into a ______________________
           - substances may be both ______________ & ______________
           -copper is very malleable & ductile
           -substances that are ductile are usually __________ very brittle


    5. Conductive: can transmit ___________ and/or ____________________
           - a substance may conduct heat, electricity, ______________, or __________
           -most metals are good conductors
           - pots & pans are made out of metals that are good _____________ conductors


    6. Soluble: can be _________________ in a __________________
           - substances that are ______________________ will dissolve in water
           -salt & sugar are soluble in water
           -substances that don’t dissolve are __________________
