Substances, Compounds & Mixtures How everything is put together.

Substances Matter that has the same composition and properties throughout is called a substance. When different elements combine, other substances are formed.

Substances Contains only one particle Can exist in 3 states of matter Can be elements or compounds Picture from http://www.ilpi.com/msds/ref/gifs/statesofmatter.gif

Compounds A compound is a substance whose smallest unit is made up of atoms of more than one element bonded together. Compounds often have properties that are different from the elements that make them up. Examples: Water, salt, sugar

Compounds Have Formulas H20 is the chemical formula for water, and H2O2 is the formula for hydrogen peroxide. The formula tells you which elements make up a compound as well as how many atoms of each element are present.

How to read a formula H20 This is a subscript. It tells us how many atoms of that element exist in one unit of that compound. Hydrogen is made of 2 H atoms and 1 O atom. No subscript is used when only one atom of an element is present.

Let’s try it… Using your white board tell how many atoms there are in each element. Sulfuric Acid H2SO4 2 Hydrogen 4 Oxygen Hydrogen Peroxide H2O2 2 Oxygen

And some more formulas… Carbon Dioxide CO2 1 Carbon 2 Oxygen Carbon Monoxide CO 1 Oxygen Calcium Carbonate (Found in shells, eggshells, antacid) CaCO3 1 Calcium 3 Oxygen

Compound Review  A pure compound has the same elements and the same amount of elements all of the time Elements are chemically combined Compound properties are different from the properties of the elements They cannot be separated physically Physical properties such as boiling point or melting point of pure substances are do not change

Mixtures A mixture is a combination of two or more substances where there is no chemical combination or reaction.

A mixture is a combination of two or more substances where there is no chemical combination or reaction.

Mixtures combine physically in no specific proportions. They just mix.

Solids, liquids and gases can be combined to create a mixture.

Mixture Types MIXTURES MAY BE HOMOGENEOUS OR HETEROGENEOUS

Homogeneous Mixtures Homogeneous Mixtures: The prefix: "homo"- indicates the same Have the same uniform appearance and composition throughout

Solutions SOLUTIONS are homogeneous mixtures

What is a solution? A solution is a mixture of two or more substances. At least two substances must be mixed in order to have a solution

A solution has two parts The substance in the smallest amount and the one that DISSOLVES is called the SOLUTE The substance in the larger amount is called the SOLVENT - it does the dissolving IN most common instances water is the solvent                         

Examples of solutions Salt water Clean Air Vinegar

Heterogeneous Mixtures: The prefix: "hetero"- indicates difference A heterogeneous mixture consists of visibly different substances or phases Two or more parts can be seen

Examples: Pizza Sandwich Chex Mix

Suspensions A SUSPENSION is a heterogeneous mixture of large particles These particles are visible and will settle out on standing Examples of suspensions are: fine sand or silt in water or Italian salad dressing

Compounds vs Mixtures Mixtures Compounds Not chemically combined Combine chemically forming molecules Can combine in any proportion Combine in set proportions Separated chemically Separated physically
