reduction of ephedrine using red phosphorus and iodine. Synthesis is relatively simple‚ but entails risk with flammable and corrosive chemicals‚ particularly the solvents used in extraction and purification; therefore‚ illicit production is often discovered by fires and explosions caused by the improper handling of volatile or flammable solvents. Most of the necessary chemicals are readily available in household products or over-the-counter cold or allergy medicines. When illicitly produced‚ methamphetamine

Naming Chemical Formulas Chemical Nomenclature There are over 19 million known chemical substances. Without some type of system‚ naming these substances would be hopelessly complicated. The system used in naming substances is called chemical nomenclature. There are two major divisions to the International Union of Pure and Applied Chemistry (IUPAC) system: inorganic nomenclature organic nomenclature Organic compounds contain carbon‚ usually in combination with hydrogen‚ oxygen‚ nitrogen

to all the possibilities and limitations when using silks. Though so similar in use‚ artificial flowers are an entirely different art form. The line‚ focal‚ filler technique is an excellent way to design artificial and dried flower arrangements. Horizontal Arrangements 1. Using a relatively shallow container‚ anchor foam with a lot of glue or use anchor pins‚ and position sprays of line flowers to establish the shape of the design. 2. Insert focal flowers in the middle so they gently droop

Harmful Chemicals in our Environment Over the past century humans have introduced a large number of chemical substances into the environment. Some are the waste from industrial and agricultural processes. Some have been designed as structural materials and others have been designed to perform various functions such as healing the sick or killing pests and weeds. Obviously some chemicals are useful but many are toxic and their harm to the environment and our health far outweighs their benefit to
