Geopolymer Eco-Concrete Compressive Strength and Elasticity Modulus Abstract Concrete is one of the most important materials that needed to build a building, or other structures.The concrete must be the best one and qualified from the strength and the efficiency. This research will explain what is geopolymer concrete. In this research, the geopolymer concrete will be examined and tested using the Universal Testing Machine(UTM), Rebound Hammer, Compressometer-Extensometer, cured by dry curing, react

Synthetic chemistry is a study were we can make man made chemical compounds as there are several types of it they include polymers which divides into several topics such as polyester Polyvinyl chloride and polystyrene which all have different properties and aspects that can be taken advantage of in many applications. This topic I was given will help me explore the impact of synthetic molecules on developing technologies and daily life as well as the implications of synthetic molecules including their

Bromination of trans- Stilbene to form 1,2- Dibromo- 1,2-diphenylethane Abstract 1,2-dibromo-1,2-diphenylethane was produced by the bromination of trans-stilbene through the addition of hydrobromic acid (HBr) and hydrogen peroxide (H2O2). This experiment was a greener bromination of stilbene because bromine was generated in situ and ethanol was used as the solvent. The melting point (243.30°C), mass (.427g), and percent yield (45.54) of the crystals were recorded. The FTIR

Experiment 3: Isolation of Chlorophyll from Spinach and Chromatography Performed February 14th and 16th By Kyle Herzog Organic Chemistry 344 Section 807 Spring 2012   Objective: The purpose of the experiment is to extract pigments from spinach leaves and separate them by column and thin layer chromatography, determining Rf values for the pigments. Equations: Rf= Distance travelled by a given compound/Distance travelled by a solvent solution 1. Crude- 4.25/5.5= 0.773 2. Carotene-

Burn rate study on Alliant (Green dot) smokeless shotgun powder and KClO4 Shalom AJ Cohen Philadelphia community college 11/2010 Abstract: The purpose of this project is to measure if differing amounts of potassium perchlorate, KCIO4, mixed with shotgun powder has an effect on burn rate. The experiment was videotaped and the duration of burn time for each amount used was recorded. KClO4, amounts ranging from .2g to 2g, were added to 4g of shotgun powder. A steel pipe that is ½ inch wide and

My science fair project is on the surface tension of water and what affects the surface tension of water. The question that I am going to ask is how does temperature and salinity of water affect the surface tension of the water. My hypothesis is that the colder and the saltier that the water is, the stronger that the surface tension of the water will be. Some of the background research that I have done has explained to me that the surface tension of water is a property of a liquids surface that

PERIODIC CLASSIFICATION OF ELEMENTS Introduction There are 115 elements that are known at present. Some elements have similar properties whereas some others have completely contrasting properties Scientists began to look for some pattern in the properties of these elements Dobereiner’s triads In 1817, Johann Wolfgang Dobereiner, a German chemist, classified elements into groups based on their properties. He kept all elements having similar properties in one group. Most of his groups had three

Atomic theory is the idea that matter is made up of small particles made of atoms. The atomic theory first had 5 points which were stated by John Dalton who came up with it. The first one was that all elements were made up of small units called atoms. The second one was that all atoms of a given element are identical to each other. Third, all the atoms were different from all the other atoms. Fourth, atoms of different elements combined together in equal numbers to form compounds. Fifth and final

#15 Synthesis of Ethyl Salicylate from Salicylic Acid ____________________________________________________________ _______________ Purpose: Salicylic acid is converted to the liquid ethyl salicylate by addition of ethanol. Yields of salicylic acid (week 1) and ethyl salicylate will be found, as well as the overall yield of the 2-step conversion of acetyl salicylic acid to ethyl salicylate. Introduction: Esters are formed from the reaction of acids and alcohols: O O
