A chemical reaction where a chemical is broken down by a reaction with water. Hydrolysis is important for the digestion of food‚ making it biologically important. 1. Condensation - The opposite of hydrolysis‚ when two molecules form one. In most biochemical reactions water is produced when the molecules join. Condensation reactions are used to build muscle tissue making them biologically important. 2. Oxidation and

properly overall. Introduction: Esters have a very sweetly fruity smell. Obviously occurring esters are found in fruits. An ester is the product of the reaction between an acid (usually organic) and an alcohol. Esters essentially result from the condensation (a reaction that produces water) of a carboxylic acid and an alcohol. The process is called esterification. This reaction can be catalyzed by the presence of H+ ions. However H2SO4 is often used as a catalyst for this reaction. This is the most

polyester chips. The process description is as follows Polyester chips are manufactured by two step chemical reactions between PTA ( Pure terephtalic acid ) and MEG (Mono ethylene glycol) The two step reaction are : Esterfication and Poly condensation Process description : PTA and MEG mixed together in paste mixing tank. Mixing of paste is done by special type of agitator. The slurry obtained in paste tank is fed to esterification reactor by screw pump. The esterification reaction is carried

1. Adsorption: Concentration of liquid or gaseous molecules over the surface of a solid material is known as adsorption. It is a surface phenomenon. (e.g.) H2 adsorption over nickel. The solid material is known as adsorbent. (e.g.) Nickel‚ Silica gel‚ Charcoal‚ Zeolite The gaseous or liquid molecules are adsorbate (e.g.) H2 gas‚ Bromine‚ benzene‚ water vapour For gases‚ a special name is given as “occlusion’ 2.If the concentration is of bulk phenomenon‚ it is absorption

variation. Carbohydrates can be broken down into monosaccharides which is a single sugar unit that can be glucose‚ fructose and galactose. This is called catabolism. Disaccharides are 2 sugar units linked together such as condensation‚ lactose‚ sucrose or maltose. Condensation allows to from water. Polysaccharides are multi-sugars. This can provide starch by glyosidic bonds. Another is glycogen. This product is stored as glucose which is reserved in the liver and muscle. Carbohydrates

is the term used to describe a substance made by joining many units together. * 2 classes of polymers based on how the mers are joined together. * Addition – mers joined without the loss of atoms (presence of unsaturated carbons). * Condensation – mers joined through the loss of atoms from the functional groups of each monomer. Radioactive isotopes: * Everything with an atomic number over 82 is radioactive. * Unstable nuclei; too many neutrons:protons‚ large nuclei * Cobalt

This is because the water vapor condensates after being gassed out of the volcanoes‚ once the condensation occurs then precipitation is created. 3) Describe the hydrologic cycle as if you were a particle of water going through it.
