Mixtures vs Solutions

All ​ (a)   can be classified as a (b)   or a mixture.

• pure substance
• matter

A ​ (a)   consists of only one type of atom or molecule. An element means there is only one type of atom present while a ​ (b)   means each molecule has more than one type of atom chemically combined.

• pure substance
• compound

In a ​ (a)   , the atoms, ​ (b)   , or particles of ​ (c)   or more different materials are mixed together but are not ​ (d)   . This means new atomic bonds do not form when substances are mixed; therefore, it is often ​ (e)   to separate a mixture back into its original materials.

• mixture
• molecules
• two
• one
• chemically combined
• possible
• impossible

In a ​ (a)   , you'll only find one kind of "thing." In a ​ (b)   , you'll find different "things."

• pure substance
• mixture

There are two types of mixtures.

• Liquid and solid mixtures
• Natural and artificial mixtures
• Simple and complex mixtures
• Homogeneous and heterogeneous mixtures

A ____ mixture is uniform throughout the mixture. This means any sample of the mixture will have the same ratio of parts.

• elemental
• homogeneous
• compound
• heterogeneous

The substances in a ____- mixture are not uniformly mixed.

• compound
• solution
• homogeneous
• heterogeneous

A (a)   mixture is (b)   throughout the mixture. This means any sample of the mixture will have the same (c)   of parts. For example, a well-dissolved beaker of (d)   is a homogeneous mixture. Any drop of the saltwater will have the same amount of (e)   and water.

• homogeneous
• uniform
• ratio
• saltwater
• salt

• The substances in a ____ are not uniformly mixed. For example, a box of granola with raisins is a heterogeneous mixture. Some scoops will have more raisins than others.

• Homogeneous mixture
• Pure substance
• Element
• Heterogeneous mixture

____ are homogeneous mixtures in which one substance dissolves in another.

• Emulsions
• Suspensions
• Solutions
• Colloids
