da Alvarenga Lab Partner: Keren Appiahene Mussie Gide 10 September 2016 Experiment 2: Acid- Base Extraction Separation of an Organic Acid‚ a Base and a Neutral Compound Introduction: The extraction technique is often used in the organic lab to separate organic compounds from mixtures. One type of an extraction technique is the acid-base extraction‚ which is used to separate organic compounds from a mixture based on their acid-base properties.1 There are certain principles that must be taken into

Visualising solid shapes Solid shapes A solid shape is a 3-dimensional shape‚ one that has depth‚ width and breadth. Examples: pyramids‚ cubes and spheres .(such as a ball) One - Dimensional Shapes A figure that has only length is called One– Dimensional Figure. For example line‚ line segments‚ ray‚ etc. One-dimensional figure does not have any width or thickness. Two – Dimensional Shapes The shape of an object located in some space is a geometrical description of the part of that space occupied

Solid Wastes Management BASURA‚ GARBAGE‚ GOMI‚ ORDURES‚ AFVAL‚ SPAZZATURA— whatever people call it‚ solid waste is a problem that must be properly managed. While it is generally understood that proper waste management helps protect human health and the environment and preserve natural resources‚ many do not realize that solid waste also impacts climate change. The manufacture‚ distribution‚ and use of products—as well as the disposal of the resulting waste—all result in emissions of atmospheric

Solid raft foundation The unified solid raft foundation is the most simple foundation form and its formwork assembling as well as its reinforcement implementation do not require hard labor. Solid raft foundation In the solid raft foundation‚ there is only one unified foundation slab. The foundation slabs are reinforced with two wire meshes‚ one placed at the

The Separation and Purification of Organic Compounds Sunshine Marie Introduction Each year‚ many thousands of new or unknown organic compounds are prepared or extracted from natural sources such as plants‚ fungi and animals. In order to identify an unknown organic compound or the components of a mixture of organic compounds‚ it is necessary firstly to separate and purify the compounds. At any given temperature‚ a certain number of molecules of a substance in the liquid state have sufficient

between the South China Sea and the Philippine Sea. With a rapidly growing population and lack of adequate disposal sites‚ solid waste has become a major problem for most medium to large-size cities. When Philippine President Gloria Macapagal Arroyo took office in January‚ 2001‚ the first act she signed into law dealt with solid waste management. In recent years‚ inadequate solid waste management systems have posed serious health risks particularly in densely populated areas. In Manila‚ for example

THE PURITY AND PURIFICATION OF SOLIDS MELTING POINTS ABSTRACT Melting points of different mixtures of naphthalene and biphenyl were examined in this lab. Samples of these various mixtures were collected and tested by different individuals in the lab in order to find the eutectic point of biphenyl. Unknown substances were then tested using the mixture melting point method in order to determine their identities. INTRODUCTION The melting point of a solid is the temperature where the substance

Students at NFV middle school are on a journey to figure out a mystery mixture. They have to search through 9 chemicals to figure out which one is it. Seems easy huh? Nope‚ they have to analyze the physical and chemical properties (a very important part in this)‚ the data‚ argue‚ and give important statements on what they think is in the mix. That’s when arguing comes in‚ not arguing on the person but the statement. I think it is citric acid and baking soda. Eighth graders have to find out what
