Concept
Demonstrations
An acid is a substance that loses protons to other substances known as bases
Formation of Hydrogen Gas from Acids
Bases can react with other substances known as "acids" by forming a new bond with the proton that originally belonged to the acid
Biological molecules are those compounds common to most all living systems; biological molecules include carbohydrates (mono- and polysaccharides), proteins, lipids (fats and oils), and nucleic acids
Inorganic Compounds
Inorganic compounds are compounds comprised primarily of elements other than carbon; there are approximately one million inorganic compounds
Oxidation of an Organic Compound
Organic compounds are compounds comprised primarily of carbon in addition to other elemests; there are approximately 18 million organic compounds
Oxidation of an Organic Compound
Reaction of Acetylene and Chlorine Gases
Covalent compounds contain atoms joined by covalent bonds which are paired electrons
Reaction of White Phosphorus and Chlorine
Ionic compounds are formed of positive cations and negative anions which are held together simply by the rule "unlike charges attract"
Metals are typified by being shiny, malleable, ductile, conductors of electricity and are found on the left side of the Periodic Table
Monomers are the building blocks for polymers
Polymers are gigantic molecules formed of individual starting molecules known as monomers
