Hello, welcome to my wiki page! My name is Haley Andrews . This page explains the __differences__ between a **mixture** and **compound**.



-- A mixture is when you combine two different materials together without causing a chemical reaction. Usually the two original components can be separated back. If you mix two things together that aren’t suppose to it can cause an explosion or some type of chemical reaction. Almost everything you can think of is a mixture. A salad is a good example of mixture because in a salad you mix vegetables, dressing, and more together and it does not make a chemical reaction occur.

 * What are two main types of mixtures? **

-- Homogeneous has the same appearance and composition through out and they are usually referred to as solutions. Homogeneous also has the prefix of “homo” meaning sameness.

-- A heterogeneous is when the different substances or phases can be seen, the three phases are gas, liquid, and solid. A heterogeneous has the prefix of “hetero” because of the differences.

-- A compound is a pure substance made of atoms that have two or more elements that are chemically combined. Some different types of compounds are Ionic bonds and Covalent bonds. Ionic bonds are when one atom donates electrons to another. Covalent bonds are when the electrons are shared with the atom.
 * What are compounds? **

-- Some examples of compounds are salt, sugar, carbon dioxide, marble, copper, hydrogen chloride, sulphate and water. Water and salt are the more common compounds. When the atoms that are in each compound join they lose their individual properties and have new properties because of the elements they are composed to.

-- There is a bonding or chemical union between the elements in a compound, but there isn’t any with a mixture. -- The compositions are fixed in compounds but in a mixture they are a variable. -- Mixtures always return back to their original properties, but compounds never do. -- Separating the energy in a compound is extremely hard, but it is very easy in a mixture. -- Also, mixtures can be made by mechanical means, while compounds can be created through chemical reaction.
