Science Fair Research Paper My Science Fair topic is about silly putty and how it is made. Chemical reaction‚is the process by which one or more substances are converted into one or more different substances.Old bonds break and new bonds form. The original substances are called reactants. The resulting substances are called products. It is a simple chemical reaction. Another simple reaction might involve a reactant molecule breaking apart. Many enduring substances such as rock and water are highly

where the structural (or repeat) unit is ÀCH2ÀCH2À and n represents the chain length of the polymer. Polymers are obtained through the chemical reaction of small molecular compounds called monomers. For example‚ polyethylene in Eq. (1.1.1) is formed from the monomer ethylene. In order to form polymers‚ monomers either have reactive functional groups or double (or triple) bonds whose reaction provides the necessary linkages between repeat units. Polymeric materials usually have high strength‚ possess

known as monomers (See Figure 1.1). An example of the relationship between a monomer and polymer is the commercially important material polyvinylchloride‚ which is comprised of the monomer vinyl chloride. The repeat unit in the monomer generally corresponds to the monomer from which the polymer was made. As with any rule‚ there are exceptions. For example‚ polyvinylchloride is formally thought to be made up of vinyl alcohol (CH2CHOH) repeat units; but factually‚ there is no such monomer as vinyl

These are composed of numerous‚ small identical subunits known as Monomers. There are 4 major polymers that are important for living organisms. These polymers are; carbohydrates‚ lipids‚ proteins and nucleic acids. B. Polymers are referred to as being organic compounds. Organic compounds are compounds that

that Earth had a chemically reducing atmosphere. This produced monomers. These monomers formed a "soup‚" that developed organic polymers‚ and the basic building blocks of life‚ in the oceans or ponds. Neither scientist had any real evidence to support their theory until Stanley Miller & Harold Urey(1953) decided to test their theory. They used a highly reduced mixture of gases- methane‚ ammonia and hydrogen- to form organic monomers like amino acids. This experiment gave support to the idea Oparin

smaller molecules that build up these chains are called monomers. Proteins are chains of amino acid monomers. Enzymes are a type of protein that catalyzes or speeds up chemical reactions. The simplest and smallest carbohydrate is called a monosaccharide or simple sugar‚ and is a single monomer. Disaccharides are two monomers joined together and polysaccharides have three or more. Hydrolysis is a process that breaks down chains of polymers into monomers. In this experiment‚ we Benedict’s reagent was used
