finding out things we do not know. Most materials in our world are mixtures. Very few materials are pure substances. The art of separating mixtures is important because it enables us to isolate pure substances. Mixtures are either homogeneous or heterogeneous. To separate a mixture there is not only one‚ but several different methods used. A mixture is a physical blend of two or more substances. An important characteristic of mixtures is that their composition may change. There are two types of mixtures

Their main target to focus on are those who suffer from substance abuse or chemical dependency. This program is not just a 12 step program that pushes people through.

The major characteristics of gases are: particles move rapidly and independent‚ fill the container they are in‚ and have the ability to flow. ● Slide 6: What are the major differences in pure substances and mixtures? A pure substance always has the same composition and intensive (internal) properties (boiling point‚ density‚ freezing point‚ temperature). Since a pure substance has a fixed composition‚ you can write a formula for it. A mixture has a variable composition therefore there is not ONE formula for it. Slide 7 and 9:

The strongest evidence points toward a negative effect of acculturation on health behaviors overall-substance abuse‚ diet‚ and birth outcomes (low birthweight and prematurity)- among Latinos living in the United States.(Lara‚ Gamboa‚ Kahramanian‚ Morales‚ & Bautista 2005). Acculturation makes it that Latino immigrants do not have to break their unhealthy behaviors. These behaviors leads to substance abuse and bad birth outcomes. “ The negative effect of acculturation on drug use‚ including marijuana

or more substances turn into a completely new substance. Physical changes can be seen through an altering of the substances physical property. A substances physical property is observed and measured without changing the composition of the subject. Descriptive words that would help to identify a substance’s physical property include hard‚ soft‚ brittle‚ flexible‚ heavy‚ and light just to name a few. When an object goes through a physical change it remains the same substance. For example

diseases such as cancer‚ heart disease‚ and HIV/AIDS. Addiction to a substance can lead to those diseases or worse‚ death. Globally‚ the misuse of legal and illegal drugs kills around 200‚000 people annually (Drug Abuse Kills). Addiction should not be taken lightly or treated like the addict’s own fault. As such‚ substance abuse should be considered a disease and treated as such in order to effectively rehabilitate addicts. Substance abuse “is a dependence on a legal or illegal drug or medication.”

For example‚ drugs‚ food‚ etc. are made by researching the chemical properties of the substance. -Matter is anything that has a mass and takes up space -Elements are the most basic substances something can be broken down into. There are about 100 elements known to scientists right now. There may be more‚ but elements with more than 100 protons are extremely unstable and may only be created
