Enzymes: Enzymes are protein molecules which catalyst the biological reactions within living systems [23]. They provide a reaction surface to which a substrate can easily bind and a suitable environment for the reaction to occur. They bring the reactants together and orient them in such a way that they attain their transition-state configurations. They weaken the high-energy bonds in the reactants, so that the reaction […]
1) INTRODUCTION: Kinetics– study of reaction rates and mechanisms Factors affecting rate: Nature of reaction (miscibilities, surface area, molecular structure) Concentration Temperature Catalysts Reaction Rates Concentration Changes Chemical kinetics is the study of the speed with which a chemical reaction occurs and the factors that affect this speed. This information is especially useful for determining how a reaction occurs. What is meant by the speed […]
An ongoing debate regarding the exact definition for heavy metal pollutant, there are many different definitions have been proposed. For example, some based on density, some on atomic number or atomic weight, and some on chemical properties or toxicity. The commonly definition of heavy metal is the element with a high (>5.0) relative density and atomic weight. Kyung Ah Moon(2007) said that”heavy metals’ as metal […]
Chromatography is a technique for separating mixtures into their components in order to analyze, identify, purify, and/or quantify the mixture or components. Separate Analyze Identify Purify Quantify Components Mixture Uses for Chromatography Chromatography is used by scientists to: Analyze – examine a mixture, its components, and their relations to one another Identify – determine the identity of a mixture or components based on known components […]
Introduction: An effective antacid should be able to neutralize adequately in order to alleviate pain and discomfort. Problem: to investigate the effect of different kinds of antacid. Compare the neutralization ability of antacids. Infer which antacid(s) tested is most effective. – Hypothesis: In this experiment I plan to use five different antacids with same mass, and use a titration method to determine the effectiveness of […]
REVIEW OF LITERATURE INTERCROPPING Intercropping of cereals and grain legumes is a neglected theme in agricultural science and practice in both conventional and organic farming systems (Dahlmann, and Von Fragstein2006). The fast rising population in many tropical countries is one of the reasons for enormous growing demand for food. The increasing urbanization due to world growing population has affected food production leading to irrevocable loss […]
Saline and Fluids Using saline as an example, outline the importance of solutions in the body and what is the concentration of ‘normal saline’ and how the concentration of saline is controlled in the body and what effects on the cells an increase in saline concentration would have. Our bodies are fifty tosixty percent water, which therefore makes water an essential fluid for ourbodies. The […]
An adhesive is a substance that sticks to the surface of an object such that two surfaces become bonded. A typical home improvement store carries many different adhesives for many different applications..The interaction of molecules is known as intermolecular bonding, or secondary bonding. Primary bonding, also known as intramolecular bonding, is the interaction of atoms within a molecule and includes covalent and polar covalent bonding. […]
INTRODUCTION: X-ray diffraction The diffraction of X-rays as they pass through a substance, usually forming an interference pattern that can be captured on film and used to analyze the internal structure of the substance. The scattering of x-rays by crystal atoms, producing a diffraction pattern that yields information about the structure of the crystal. X-ray diffraction is used in x-ray crystallography . X-ray diffraction – […]
