line I learned about the different structures of atoms. Amanda Bynes 2.2 assessment p.5 pg. 44 October 2nd 1a. What does it mean when a molecule is said to be “polar”? -Because the molecule is a bit like a magnet with two poles. 1b. How do hydrogen bonds between water molecules occur? -The attraction between a hydrogen atom with a partially negative charge. 2b. Why is water such a good solvent? -Because water easily dissolves salts‚ sugars

assignment‚ you will build models of molecules in order to answer questions about their shape and chemical properties. Materials: * multicolored gumdrops‚ marshmallows‚ or other soft candy (to represent atoms in each model) * toothpicks (to represent the covalent bonds in each model) * paper (to draw Lewis dot structures and pictures of the models) Introduction: Chemists often use three-dimensional models to help represent the geometry‚ or shape‚ of molecules. You can purchase a molecular

It is also said that an organic compound is any member of a large class of chemical compounds whose molecules contain carbon and hydrogen but carbides‚ carbonates‚ carbon oxides and elementary carbon are not organic compounds. Carbon compounds make up the structure of all living things. Organic chemistry is the study of carbon compounds. Nearly all compounds

Gel Filtration Gel filtration is a non-adsorptive chromatography technique that separates molecules on the basis of molecular size. Desalting and buffer exchange are two special examples of gel filtration that are widely used in many downstream bioprocesses. Desalting is used to completely remove or lower the concentration of salt or other low molecular weight components in the sample while buffer exchange replaces the sample buffer with a new buffer. Gel filtration is one of the easiest chromatography

INTRODUCTION In 1791 Luigi Galvani discovered electrical activity in the nerves of the frogs that he was dissecting. He thought that electricity was of animal origin and could be found only in living tissues. A few years later‚ in 1800 Alessandro Volta discovered that electricity could be produced through inorganic means. In fact‚ by using small sheets of copper and zinc and cloth spacers soaked in an acid solution‚ he built a battery - the first apparatus capable of producing electricity. Naysayers
