Ionic – A chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion. Covalent - A chemical bond that involves sharing a pair of electrons between atoms in a molecule. 2. Explain the structure of metals‚ ionic compounds‚ covalent molecules and covalent

doubted himself. Grant Achatz‚ is the only American chef to master the art of Molecular Gastronomy. People sought after progressive cuisine to at least experience it once. This family man and cancer survivor is a prime example of heroism. With knowledge of molecular gastronomy‚ there’s some weight to his name. Being able to take foods and give them new tastes and textures‚ is what gave his cuisine’s popularity. Molecular gastronomy is seen as “manipulating” the ingredients‚ instead of cooking them

MOLECULAR DETECTION OF FUNGAL DISEASES INTRODUCTION With the rise of many new diseases caused due to viruses‚ bacteria and fungi; it is essential for the rapid detection of such diseases. The severity of such diseases can be reduced by its rapid detection carried out by different methods. The conventional methods may include the idea of just identifying the disease symptoms‚ identification of these pathogens in the laboratory by different morphological and biochemical tests‚ etc [1]. The conventional

Introduction Vibration spectroscopy is one of the most important tools for the accurate determination of molecular structure. Vibration spectroscopy also plays an important role in environmental chemistry. For example‚ the albedo of the earth’s atmosphere is controlled by the absorption of infra-red light by green house gasses‚ which include CO2‚ H2O‚ and CH4

Characteristics of Gases Section 10-1 The Kinetic-Molecular Theory of Matter Prerequisites The kinetic-molecular theory is based on the idea that particles of matter are always in motion. The theory can be used to explain the properties of solids‚ liquids‚ and gases in terms of the energy of particles and the forces that act between them. ideal gas: an imaginary gas that perfectly fits all the assumption of the kinetic-molecular theory. Kinetic-Molecular Theory of Gases (based on the following

Experimental Prep and Optimum wavelength Selection An ionic Iron solution with a known concentration of 4.047x10-3 M was obtained. A 250-mL sample of a 10-fold dilution of this ionic iron solution and 5 drops of concentrated HNO3 was made. This solution served as the source of ionic Iron for the remainder of the lab and was labeled “stock ionic Iron solution.” Next‚ a 50-mL aqueous ionic Iron and FerroZine® complex solution was prepared by adding 5.00mL stock ionic Iron‚ 3-mL of acetic acid buffer‚ 2-mL of 5%

Collecting Butane Gas The purpose of the lab was to determine the molecular mass of Butane‚ and this was done by using the ideal gas law (PV=nRT). The materials used were: match‚ funnel‚ bucket‚ cylinder‚ thermometer‚ lighter‚ scale‚ and a wooden flynt. These materials are used to help collect and test the Butane gas. Butane gas was used because it is ideal at standard temperature and pressure. Procedure: 1. Rinse bucket and fill three fourths full. 2. Rinse all glassware. 3. Place
