Peter Debye and his Contributions to Chemistry Abstract Dutch physicist Peter Debye studied under Arnold Sommerfeld‚ and developed several approaches using induced dipole moments and x-ray diffraction to study molecular structures. In 1912 he exhibited the Debye equation for dipole moments‚ a method to determine bond angles and the degree of polarity of covalent bonds‚ which allows the spatial configuration of molecules to be deduced with far greater accuracy than had previously

Alpha amylase is an enzyme that aids in the breakdown of starch and glycogen to form glucose and maltose through the hydrolyses of alpha linked polysaccharides1. Starch is a complex carbon and is the main energy storage material found in plants and some bacteria. It is a major component of food as it supplies plants with energy and carbon. Starch consists of two types of polysaccharides called amylose and amylopectin1.The properties of starch can depend on the number of alpha 1‚4 glycosidic bonds

1) Demonstrate understanding of the terms atom and molecule. Atom= Smallest Unit of Matter Molecule= 2 or more atoms chemically bonded. 2) Describe paper chromatography. 3) Interpret simple chromatograms. A method used to separate a Solution‚ using a Paper and a beaker of water. The Substances in the Paper go up depending on their Mass. We can say that a Solution has the same substance as another solution because they form a line of the same height. 4) Describe methods of separation

The Supporting People programme RESEARCH PAPER 12/40 16 July 2012 The Supporting People programme was launched in 2003 as a £1.8 billion ring fenced grant to local authorities intended to fund services to help vulnerable people live independently. The level of the grant was reduced in subsequent years‚ and in the 2010 Spending Review the Government announced that the Supporting People national funding levels would decrease from £1.64 billion in 2010/11 to £1.59 billion in 2014/15.

tarnishing silver) Also‚ almost all chemical reactions involve exchange of heat (or energy): in combustion reactions great deal of heat is released in neutralization reactions and others. Transfer of heat is a major theme of thermodynamics‚ the science of heat exchange (or energy exchange). Q: Why it is important to know the quantity of heat (energy) involved in a chemical reaction? Answer: when chemical reaction takes place the rearrangement of atoms takes place and some bonds have

________________________________________ In the balcony scene‚ when Juliet expresses her fear for Romeo’s safety‚ Romeo replies that it’s ok if her kinsmen find him‚ because his "life were better ended by their hate‚ / Than death prorogued [postponed]‚ wanting of [lacking] thy love" (2.2.77-78).
