Organometallic chemistry

ABSTRACT Heterogeneous photocatalysis, has been reported to be effective for the degradation of a wide range of model pollutants in suspension. The use of nanostructured materials is one approach to improving photocatalytic efficiency. Therefore, this work is based on the use of nanomaterials such as titania and silver-zinc oxide photocatalysts to degrade amoxicillin trihydrate (a model antibiotic pollutant) in suspension under UV-C irradiation and compares the efficiencies of the photocatalysts

Mary Pyrdol Honors Chemistry P3 Group 3 Topic: Antacid Potency Due Date: 9/30/16 Background Research For the scientists project, they are researching different brands of antacid and their potency to further expand their knowledge of acids, bases, and neutralization. Their problem statement is ‘which liquid antacid brand is most potent?’ In the scientist’s experiment, their independent variable is the brand of liquid antacid. The dependent variable is the amount of drops of antacid it takes for the

Robert Boyle had an assumption that an element was an individual substance that could not be broken down further into a smaller substance through the process of a chemical reaction. Boyle’s assumption is considered to be the beginning of modern chemistry. 1789 Antoine Lavoisier created a list of substances that he considered to be elements. He separated his list of 33 elements into metals and non-metals. Some items on the list were classified as compounds because they could not be determined to

Abstract: The purpose of this lab is broken into two parts. The first is to identify the unknown compound by identifying its physical and chemical properties. Using various tests, the collected can be used to compare compounds to the UWC. The second part of identifying the compound is synthesizing the compound and then testing the created compound. The information gathered from days one and two were used to compare and verify the results. Introduction: Given the unknown compound, the goal was

Science is the exploration of discovering life and the impact it has on people and the atmosphere. All around us is the opportunity to learn daily about something related to the field of science and how it impacts us and our surroundings. In my autobiography I will share with you my journey in learning and experiencing science in my personal life. I hope that my experiences and perspective on teaching sciences and discovering it will guide me and help me as I become a teacher myself. I believe a

Group 14 of the periodic table contains a mixture of non-metals (carbon and silicon), a metalloid (germanium), and two metals ( tin and lead). Tin is able to form dihalides and tetrahalides such as SnI2 and SnI4. However, lead will not form tetrahalides as readily as tin3. The tetrahalides of lead will decompose into dihalides due to their instability 3. The stability of the compounds is based on their respective oxidation states. Periodic trends suggest that group 14 oxidation states are normally

Grade level: FOUR Experiment: Does the length of the candle affect the duration of ignition under the cups of the small size. OBJECTIVE OF ACTIVITY: To demonstrate that the length of the candle affect the duration of ignition under the cups in small size. DESCRIPTION OF THE ACTIVITY: The activity will be conducted on candles and cups will be used as models to investigate the process of ignition. Experiment will make the students learn three skills categories i.e.

Energy: capacity to do work or transfer heat Kinetic energy: energy of motion; equal to ½ mv^2 Potential energy: stored energy or energy of position Joule: basic unit of energy in the International System of Units; equal to 1 newton-meter Calorie: the energy needed to raise the temperature of 1 gram of water through 1 °C (about 4.1868 joules) Law of conservation of energy: natural law describing that energy is neither created nor destroyed in any process Kelvin scale: SI temperature scale with

Water is a very important resource, every life depends on fresh water to survive. There are three per cent of fresh water of the world’s water and all life on earth can only depends on half of it. Water has become a very fragile resources because, people have damaged the water bodies badly from the use of chemicals, irrigation to household. Consequently, these reasons have severely affected the water, the environment and many lives on earth. Industrial wastes link to a significant cause of damaging

Introduction: In order for this experimental investigation to be conducted successfully with maximum efficiency, chemical theories must be accurately applied. For this investigation, various concepts and theories will be discussed and applied to the two methods- gravimetric and colourimetric- of analysing the precipitate and solution created. One specific variable will be chosen to be manipulated in order to study and analyse. From this, the most effective and accurate method of analysis of percentage
