Colegio Americano Del Noreste Drugs Miss: Nancy Mario Fabrizio Curzio Aguirre Grade: 9° Group: “A” December 3, 2013 How do the drugs affect the brain? When drugs get into the bloodstream they are carried to all parts of the body and some reach the brain. The quicker the drug reaches the brain, the more intense the effects. The quickest way to get a drug into the brain - and also the most dangerous way of using any drug - is to inject it intravenously, or into the vein. Almost as quick

CRYSTAL STRUCTURES CRYSTAL STRUCTURES • Have you ever wondered how atoms assemble into solid structures? • How does the density of a material depend on its structures? CRYSTAL STRUCTURES • Solid materials can broadly be classified as crystalline and non crystalline (amorphous) solids. • In crystalline solid the arrangement of atoms is in a periodically repeating manner whereas no such patterns are found in a non-crystalline solid. CRYSTAL STRUCTURES • 2 types of crystalline solids:

valve is often more efficient than other designs that do not use one. A thermal expansion valve is a key element to a refrigeration cycle; the cycle that makes air conditioning, or air cooling, possible. A basic refrigeration cycle consists of four major elements, a compressor, a condenser, a metering device and an evaporator. As a refrigerant passes through a circuit containing these four elements, air conditioning occurs. The cycle starts when refrigerant enters the compressor in a low pressure

position (gravitational). It exists in various forms. Chemical Energy Chemical energy is the energy stored in the bonds of atoms and molecules. Biomass, petroleum, natural gas, propane and coal are examples of stored chemical energy. Nuclear Energy Nuclear energy is the energy stored in the nucleus of an atom - the energy that holds the nucleus together. The nucleus of a uranium atom is an example of nuclear energy. Stored Mechanical Energy Stored mechanical energy is energy stored in objects by the application

LIPIDS Composition Elements – Carbon, Hydrogen and Oxygen Structure How are Triglycerides Formed Lipids are formed when 3 fatty acids combine with glycerol. Glycerol is an alcohol – it has 3 hydroxyl (OH) groups. To each of these OH groups, a fatty acid attaches itself. Each time this happens water is eliminated. The result is a triglyceride (this is the chemical name for lipids). Show diagram of triglyceride formation Fatty Acids Lipids are made up of a number of different

a very explosive topic. Azide compounds contain three nitrogen atoms connected to each other, -N3, where the letter N denotes an atom of the element nitrogen. The three significant nitrogen atoms bonded to each other. There are two type of azides, organic azides and other are inorganic azides. In organic azides, the three nitrogen atoms are connected to a carbon atom and in inorganic azides they are connected to a metals atoms. (ChemNote: Azides) The discovery of the organic azide by the Peter
