Classifying Matter and it’s properties Ch. 3 Notes Classifying Matter and it’s properties

Objectives Introduce Chemistry SWBAT explain the differences between the TWO major classifications of matter SWBAT explain some of the similarities and differences of the properties of these groups

Chemistry The study of the composition, structure, properties, and reactions of MATTER.

Matter A physical substance. It occupies space (has a volume) It has a mass.

HOW CAN MATTER BE CLASSIFIED? Matter can be classified by…. …its state. solid liquid gas

HOW CAN MATTER BE CLASSIFIED? Matter can be classified by…. …its state. …its color.

HOW CAN MATTER BE CLASSIFIED? Matter can be classified by…. …its state. …its color. …its uses.

Matter has mass and volume Pure Substance Made up of one type of particle Ex. Sugar, gold, lead, water, etc.

The rest are all the same particles. pure substance A pure substance is made up of all the _________ of particles. same type This is one particle. The rest are all the same particles.

Matter Element has mass and volume Pure Substance Made up of one type of particle Ex. Sugar, gold, lead, water, etc. Element Made up of a single type of atom. Anything on the periodic table

element Au Au Au Au Ni Ni Ni Ni Elements are made up of all the same particles called _____ . atoms Elements are made up of all the same ______________. individual atoms Au Au Au Au Au gold Ni Ni Ni Ni Ni nickel

element Elements are listed on the ___________ . periodic table platinum iodine mercury sodium manganese chlorine

Matter Compound has mass and volume Pure Substance Made up of one type of particle Ex. Sugar, gold, lead, water, etc. Element Made up of a single type of atom. Anything on the periodic table Compound Particle made from two or more different kinds of atoms. Water (H2O), Carbon dioxide (CO2), etc.

compound O H C O O H C O C O O H C O C O O H C O Made up of all the same particles called ________ . Each molecule is made up of ________________________ molecules . two or more different atoms O H C O O H C O C O water H2O carbon dioxide CO2 O H C O C O O H C O H2O2 hydrogen peroxide carbon monoxide CO

compound N H Examples of common compounds. NH3 ammonia CH4 methane C6H12O6 glucose C6H6 benzene C3H8 propane

Mixture Matter has mass and volume Pure Substance Made up of one type of particle Ex. Sugar, gold, lead, water, etc. Mixture Made up of TWO or MORE different kinds of particles Chocolate milk, salt water, sand Element Made up of a single type of atom. Anything on the periodic table Compound Particle made from two or more different kinds of atoms. Water (H2O), Carbon dioxide (CO2), etc.

mixture A mixture is made up of __________ different types of particles/substances. two or more

Matter has mass and volume Homogeneous Mixture Pure Substance Mixture Made up of one type of particle Ex. Sugar, gold, lead, water, etc. Mixture Made up of TWO or MORE different kinds of particles Chocolate milk, salt water, sand Element Made up of a single type of atom. Anything on the periodic table Compound Particle made from two or more different kinds of atoms. Water (H2O), Carbon dioxide (CO2), etc. Homogeneous Mixture Made up of TWO or MORE different kinds of particles They blend well and are evenly spread out You can’t tell the types of matter apart Salt water, tea, ice cream

homogeneous mixture Homogeneous mixtures are also called ________. solutions Made up of different particles that blend well and are __________________. uniformly distributed wine salt water tea The different particles are so small that they __________ with one another. mix evenly air a solution of gases (N2 and O2 mostly)

Heterogeneous Mixture Matter has mass and volume Pure Substance Made up of one type of particle Ex. Sugar, gold, lead, water, etc. Mixture Made up of TWO or MORE different kinds of particles Chocolate milk, salt water, sand Element Made up of a single type of atom. Anything on the periodic table Compound Particle made from two or more different kinds of atoms. Water (H2O), Carbon dioxide (CO2), etc. Homogeneous Mixture Made up of TWO or MORE different kinds of particles They blend well and are evenly spread out You can’t tell the types of matter apart Salt water, tea, ice cream Heterogeneous Mixture Made up of TWO or MORE different kinds of particles They DO NOT blend well because they are too big You can easily tell the types of matter apart M&Ms, sand, etc.

heterogeneous mixture The different particles are so large that they do NOT evenly mix with one another Made up of different particles which are ______________________. NOT uniformly distributed (e.g. salt and pepper mixture) or they are chemically unable to mix with one another (e.g. oil and water).

heterogeneous mixture Made up of different particles which are ______________________. NOT uniformly distributed laundry sand shots salad

Special Types of Mixtures Solution – a homogeneous mixture where one substance dissolves completely into another, and looks uniform throughout. The substances cannot be separated easily Ex. Sugar and water, salt and water Sugar Water Solution

Suspension – a heterogeneous mixture that will separate into layers over time. Its parts can be separated fairly easily. Ex. Sand in water. Drinks that say “shake well”

suspension after being shaken suspension after settling cornstarch and water suspension suspension after being shaken suspension after settling
