 * Difference Between Homogeneous and Heterogeneous**
 * Homogeneous**
 * Homogeneous mixtures are a substance in which components are evenly mixed. It has to be two or more substances and the substance has to stay the same throughout.
 * Homogeneous mixtures are also called solutions and they are formed when one substance dissolves into another substance.
 * Most homogeneous mixtures can be considered solutions, but since the rule is two or more substances a 50:50 mixture is technically not a solution.
 * Some mixtures start out as heterogeneous mixtures but can be turned into a homogeneous mixture by shaking the substance.
 * A reaction between two gases, two liquids or two solids is homogeneous.
 * To make it simple, think of Gatorade, it has salt and sugar and all those different things in them but all you can see is the colored liquid.


 * Heterogeneous**
 * A reaction between a gas and a liquid, a gas and a solid or a liquid and a solid is heterogeneous.
 * Heterogeneous can be colloids, emulsions and suspensions.
 * Things that need to be shaken are usually suspensions because they begin as a heterogeneous mixture.
 * A heterogeneous mixture is basically a mixture with a substance in which components are not evenly mixed.
 * This is a heterogeneous mixture because you can see all of the different things like the meat, the onions, the peppers and the mushrooms.
 * To be a heterogeneous mixture you have to have at least 2 or more substances. They also cannot be evenly mixed; you also have to be able to see different substances and parts.

 * The Differences Between Heterogeneous and Homogeneous Mixtures**
 * The difference between the two is that heterogeneous mixtures you can see the different mixture but in homogeneous you can’t.
 * The combinations with the gas, liquid and solid substances are different and so are the foods. What I mean by that is, there can’t be a food that is a homogeneous and a heterogeneous mixture.
 * We use see these mixtures every day in our lives, we just don’t take the time to figure out what kind of mixture they are.




 * Glossary**
 * Homogeneous mixtures: A substance with two or more components that are evenly mixed or the same throughout. To make it simple, you can’t see the different components or parts.
 * Heterogeneous mixtures: A substance with two or more components that aren’t evenly mixed and don’t stay the same throughout. You can see the different components and parts.
 * Components: An ingredient or a small part of a substance. Like pepperoni on pizza, it is an ingredient on pizza.
 * Substance: Food that is made up of different components or parts. Like a pizza, it has components like dough, crust, toppings, cheese and tomato sauce.
 * Solutions: Is the same as a Homogeneous mixture because it is just a gas, liquid or solid dissolving evenly into another gas, liquid or solid.
 * Emulsions: Any colloid like suspension of a liquid in another liquid.
 * Colloids:A colloid is a substance microscopically dispersed evenly throughout another substance.
 * Suspensions: the particles of a substance are mixed with a fluid but are not dissolved.
