Classification of Matter

Front

What is a pure substance?

Back

A pure substance is a material that has a constant composition and consistent properties throughout. Examples include elements like oxygen and compounds like water.

Front

What is a homogenous mixture?

Back

A homogenous mixture is a mixture in which the components are uniformly distributed and cannot be distinguished from one another. Examples include saltwater and air.

Front

What is a heterogenous mixture?

Back

A heterogenous mixture is a mixture in which the components are not uniformly distributed and can be easily distinguished. Examples include salad and sand.

Where are the reactants located in a chemical equation?

Back

The reactants are located on the left side of the arrow in a chemical equation.

A pure substance has a uniform and definite composition, while a mixture contains two or more substances that retain their individual properties.

Front

What is the significance of the Periodic Table?

Back

The Periodic Table organizes all known elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What is an example of a homogenous mixture found in everyday life?

Back

An example of a homogenous mixture is vinegar, where the acetic acid is evenly distributed throughout the water.

Front

What is an example of a heterogenous mixture found in everyday life?

Back

An example of a heterogenous mixture is a bowl of cereal with milk, where the cereal pieces can be seen and separated from the milk.

Front

What happens to the properties of substances in a compound?

Back

In a compound, the properties of the individual elements change and are different from the properties of the compound itself.
