​

• 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

Multiple Choice

______________ is a chemical property.

• Reactivity with oxygen

• Magnetism

• Solubility

• Mass

• Melting Point

Signs of a Chemical changes

Multiple Choice

How are chemical properties observed?

• during chemical reactions

• when a chemical is poured in a beaker

• when a chemical is at room temperature

A Chemical Property of Sodium

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

Rust

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

Multiple Choice
