Unit 1: Classification of matter

Front

What is a heterogeneous mixture?

Back

A mixture in which different materials are unevenly distributed and can be easily identified, such as mixed nuts or dry soup mix.

Front

What is a pure substance?

Back

A material that has a constant composition and consistent properties throughout, such as baking soda (NaHCO₃).

Front

What is a mixture of compounds?

Back

A combination of two or more compounds that do not chemically bond, resulting in a substance that retains the properties of the individual compounds.

Front

What does a particle diagram represent in terms of matter classification?

Back

A visual representation that can help classify matter as an element, compound, or mixture based on the arrangement and types of particles.

Front

What is a colloid?

Back

A type of mixture where tiny particles are dispersed throughout another substance, such as gelatin.

Front

What is a suspension?

Back

A heterogeneous mixture in which solid particles are suspended in a liquid or gas and can settle over time, like muddy water.

Front

What is a compound?

Back

A pure substance formed when two or more elements chemically bond together, such as water (H₂O).

Front

What is an element?

Back

A pure substance that cannot be broken down into simpler substances by chemical means, such as oxygen (O) or gold (Au).

Front

What is a homogeneous mixture?

Back

A mixture in which the composition is uniform throughout, and the different components are not easily distinguishable, like saltwater.

Front

How can you identify a mixture?

Back

By observing if the components can be separated physically and if they retain their individual properties.
