elements compounds, mixtures, and solutions

Element

A pure substance that cannot be broken down or separated into similar substances

Pure substance

Substances in which there is only one type of particle

pure substances can be a

Element or a compound

Compound

Composed of two or more substances that have been chemically combined

Compounds are formed when two or more element

Chemically bond

To make a compound you must undergo

Chemical change

Mixture

When two or more substances physically combine

In a mixture, the substances keep their own

Properties

When a compound is formed,

New properties are formed

Mixtures can be separated by physical means

Straining for large particles

Filtering for small particles

Evaporation

Magnetism

Distillation involves boiling

Centrifuge involves spinning to separate density

Heterogeneous mixtures

Appears different throughout

Examples are concrete soil, pizza, and salad

Homogeneous mixtures

Appears the same throughout

Examples, milk, chocolate, milk, coffee, chocolate, and ice cream

Solution

Same as a homogeneous mixture, the particles are evenly distributed and appears the same throughout

solute

The substance that is dissolved

Example, examples are sugar and salt

Solvent

The base substance that the solute dissolves into

Examples are water and milk

Soluble

Able to dissolve

Insoluble

Not able to dissolve

Saturated

Full of solute cannot dissolve anymore

Supersaturated

Holding more solute than normal

Concentrated-strong

Unsaturated

Holding less than normal can hold more not full

Dilute-week
