Organic molecules are the molecules of life that include Carbon and Hydrogen. Organic molecules consist of four important classes which are lipids‚ carbohydrates‚ proteins and nucleic acids. The most important organic molecule is Carbon. Carbon can form with up to 4 different atoms to form chains‚ rings and branches. Organic molecules also contain monomers. Monomers are the “building blocks” of macromolecules. Macromolecules are made up by chains of monomers‚ these are called polymers. Continuing

Redox Reactions Reactions involving oxidation and reduction processes are very important in our everyday world. They make batteries work and cause metals to corrode (or help to prevent their corrosion). They enable us to obtain heat by burning fuels--in factories and in our bodies. Many redox reactions are complex. However‚ combustion and synthesis (from elements) are two ordinary examples which require very little description. Just a little more involved are the displacement reactions‚ with

the R Lab 1. One mole of hydrogen gas has a mass of 2.02 g. Use your value of molar volume to calculate the mass of one Liter of hydrogen gas at STP. The density is in g/L. Compare your value to a literature value? (Consult a hand book or text book) 2. In setting up this experiment‚ a student noticed that a bubble of air leaked into the gas tube when it was inverted in the water bath. What effect would this have on the measured volume of hydrogen gas? Would the calculate value

Death is an unavoidable occurrence in life‚ but the forms vary in the way that people may describe a death or may be a feeling of what might feel like death. Both W.H. Auden who wrote the poem Stop all the Clocks and Gwen Harwood who wrote the poem Barn Owl have both shown the idea of death in their poems. In the first part of the poem Barn Owl a child at a rebellious age‚ experiments with the constraints of authority in an attempt to seek control for herself‚ as the child sneaks out to kill a

aim to find out the order of reaction with respect to [H2O2] and [2I-]. I aim to find out the activation enthalpy of the reaction by finding the rate of reaction at different temperatures using the Arrhenius Equation. The experiment will go as follows: Into a conical flask put 15cm3 of distilled water and add 2cm3 of [X]moldm-3 potassium iodide (KI) solution and 1cm3 of 2moldm-3 sulphuric acid. Then add to this 2.5cm3 of 5vol (0.42moldm-3) hydrogen peroxide (H2O2). For the second part

There are lots of forms of film elements used and shown throughout the movie‚ but one particular symbol focuses on is the use of clocks and how it helps shape the movie and the idea Chbosky is trying to get across. The scenes throughout the movie subtly have clocks placed and certain times being announced in the film to insure the idea that although time may seem to drag on forever‚ time also goes by extremely fast.

Title An investigation of the effects of schemas on drawing a clock. Introduction A schema according to Henry Gleitman (2007) is a mental representation that summarises what we know about a certain event or situation. Schemas reflect the fact that many aspects of our experience are redundant and schemas seek to provide a summary of this redundancy. When an individual encounters an event or situation‚ they seek to understand it by relating it to a schema. Schemas are useful not only in providing

Prashant Zanwar University of Central Florida I. Introduction To Maglev Technology And Application 1.1 Principle of Maglev System Maglev is a system in which the vehicle runs levitated from the guideway (corresponding to the rail tracks of conventional railways) by using electromagnetic forces between superconducting magnets on board the vehicle and coils on the ground. The following is a general explanation of the principle of Maglev. fig. 1.1 1.1.1 Magnetic Levitation The "8" figured levitation

Movie Essay In the essay titled‚ “The Tyranny of the Clock” by George Woodcock and the film‚ “ Nick of Time” demonstrates how the movement of the clock sets the tempo of the lives of people. People become the servants of time‚ always hurrying through meals‚ rushing to catch busses or trains‚ all contribute as examples of our regular routines in life. The clock influences the habits of people by making them do things that ruin their health and shorten their life because they are so overwhelmed
