Chemical Properties of Matter

​

• Describes how the substances may change when it transforms through a chemical reaction​ (reacts with another substance)

• Changes the identity of the original substance​

​Chemical Properties

Chemical changes can't be "undone", since the substance has changed into something new!

• The ability to burn involves a substance reacting quickly with oxygen to produce light and heat. This process is called burning

​

1) Flammability

• how likely is it to react with other chemicals/substance

• Signs of a chemical reaction to look for:

  • Release of heat or light

  • Color change

  • Formation of a gas

  • ​Formation of a precipitate (solid falling out of a liquid)

​

2) Reactivity

Signs of a Chemical changes

The element Sodium has the ability to react with water. Watch the following video to see what happens when sodium and water react.

• when a substance reacts with oxygen to give off heat & energy

• Heat & energy are produced in this reaction

​

3) Combustion

• when a substance reacts with oxygen

• changes in color

​

4) Oxidation

The ability of a substance to rust is a chemical property that involves a substance reacting slowly with oxygen

• Endothermic- absorbs energy from its surrounding in the form of heat

• Exothermic- releases energy into its surroundings (gives off heat)

​

5) Endothermic or Exothermic

• measuring how acidic or basic a solution is

6) pH
