Distillation Column In the the Chemical Enginneering Lab at CSULB there is a total reflux eight-stage glass binary distillation column at atmospheric pressure. The components that need to be separated are 1-propanol and 2-propanol. These two compounds are isomers with fairly close boiling points. They are separated based on their physical propertis. With the

Meiosis I Prophase I: - nuclear membrane dissolves * centrioles move to poles * spindle fibres forming * DNA has been replicated and forms chromosomes made of 2 identical chromatids * Homologous chromosomes line up to form a bivalent‚ 2 chromosomes or 4 chromatids (TETRAD)‚ this process is called SYNAPSIS * Where chromatids overlap is called a CHIASMATA‚ and it allows for CROSSING OVER of genetic information between chromosomes Metaphase I: - homologous chromosomes

rain‚ strong winds and a variety of stormy cumulus clouds; all of which associated with rapidly rising warm air and cloud forming condensation where the warm air meets colder air. At the warm front‚ at the rear of the depression‚ the warm air is still essentially being displaced but the weather here is milder since the clouds formed are more the result of condensation at the meeting of cold and warm air‚ as opposed to the warm air rapidly rising. A depression is formed where these two fronts meet

Piers tries to touch all the aspect of sciences and give the briefly and somewhere even detail overview on every beats and pieces of all the aspects of science. Each part starts with very good scientific background with his research and clear definition before moving on to a more in-depth exploration of its coverage. Piers Bizony

AP Chemistry Chapter 13 Outline Condensed phases: the liquid and solid phases; phases in which particles interact strongly. 13.1 Gas condensed when cooled and compressed. In the liquid state the forces of attraction among particles are great enough that disordered clustering occurs. It is hard to compress a liquid. Liquids diffuse into other liquids with which they are misicible. The natural diffusion rate is slow at normal temperatures. Cooling a liquid lowers its molecular kinetic energy

Core 1 summary notes 1) Fossils fuels provide both energy & raw materials such as ethylene‚ for production of other substances Identify the industrial source of ethylene from the cracking of some of the fractions from the refining of petroleum Catalytic cracking is the process whereby high molecular weight fractions are broken down to low molecular weight ones. This process is used in petroleum refineries where crude oil is broken down to smaller alkenes and alkanes‚ until ethene‚ propene‚
