Physical and Chemical Changes (Write down the stuff in Magenta)

Physical Properties Describe things that can be detected with the senses Describe the phase of matter that something is in

Chemical Properties Describe the way substances react with each other

Physical Changes Changes in size or shape Changes in phase

Chemical Changes Something new is created

Breaking into smaller pieces Melting Changing shape Evaporating

Fire = chemical change A gas is given off (bubbles) A color change happens (by itself) Different smell Release of heat

Sodium is a shiny silver solid that explodes violently

Chlorine is a greenish gas that is poisonous

Sodium Chloride (table salt) is a white crystal that is essential for human life.

Reactants  Products Sodium + Chlorine  Sodium Chloride Na + Cl  NaCl

Reactants  Products Iron + Oxygen  Iron Oxide (Rust) Fe + O  Fe 2 O 3

Reactants  Products Water + Carbon Dioxide  Oxygen + Glucose H 2 O + CO 2  O 2 + C 6 H 12 O 6
