READ ALOUD!

At the end of the lesson, I will be able to:


• define matter and what is the chemistry behind matter.
• differentiate the chemical and physical properties of matter
• identify the different properties of matter

Chemistry : The Study of Change
▪ Chemistry is the Study of matter and the
changes it undergoes.

▪ Chemistry is often called the central


science, because a basic knowledge of
chemistry is essential for students of
biology, physics, geology, ecology, and
many other subjects

This refers to the characteristic or trait of matter that can be observed
or perceived with our senses easily without changing its chemical
composition.

composition remains unchanged.

are converted to new kinds of matter with different compositions. The
key to identifying chemical change, then, comes in observing a change
in composition.
Chemical Property
• Combustibility/Flammability

• Oxidation

• Reactivity
Chemical Property
Zinc reacts with hydrochloric acid
solution to produce hydrogen gas and a
solution of zinc chloride in water. This
reaction is one of zinc s distinctive
chemical properties, just as the inability
of gold to react with hydrochloric acid is
one of gold’s chemical properties.
Sodium reacts not only with hydrochloric
acid but also with water.
Chemical Property

Paper is a complex material,


but its principal constituents are carbon,
hydrogen, and oxygen. The chief
products of the combustion are two
gases, one consisting of carbon and
oxygen (carbon dioxide) and the other
consisting of hydrogen and oxygen
(water, as steam).

Mixture
• A mixture is a material composed
of two or more simpler substances
in chemistry. Such materials can
be compounds or chemical
elements. A mixture of liquids,
solids, or gases can be produced.

• Ex: Coffee, Air, Vinegar, Soda with


ice, Sandwich and salad.

Homogeneous Mixture - The composition of homogeneous mixture is
same through out.

Heterogeneous Mixture - The composition of heterogeneous mixture is
not uniform.
