Description A small conical heap of orange ammonium dichromate is ignited. It sparks and produces a large volume of green chromium (III) oxide as well as steam, resembling a volcano. Apparatus Bunsen burner, heatproof mat. Metal tray such as a large tea tray. Watch glass. Bell jar (optional). One 1L conical flask (optional). One 250mL conical flask...

Liberato Cardellini Dipartimento di Scienze dei Materialie della Terra Universita, Via Brecce Bianche 60131 Ancona, Italy INTRODUCTION An important part of every general chemistry curriculum is the treatment of ionic equilibrium problems in aqueous solution. In this topic, two important aspects of stoichiometric calculations are treated: 1) the con...

Roy Tasker and Kris Basden University of Western Sydney, Nepean What colour is liquid oxygen? Is Bugs Bunny a vampire under treatment? Why does garlic keep Count Dracula away? Why is eating too much bacon and orange juice unhealthy? How can a submerged mouse breathe in liquid without drowning? Why do babies born to smokers weigh about 5% lighter th...

Peter Southwell-Keely University of New South Wales Introduction In this lecture I shall briefly summarise the history of the world from an oxygen point of view, say something of the discovery of oxygen, why we need it, its use as a chemotherapeutic agent and its toxicity. I shall then give some examples of reactions which demonstrate its reactivit...

Michael J.B. Moore University of Canterbury Private Bag 4800 Christchurch, New Zealand INTRODUCTION The kidney transplant has become both a routine and common practice over the latter half of the 20th century. The procedure has a high success rate reflecting the low risk involved in this operation relative to other more complex transplants such as ...

M.A. HOOPER School of Chemistry, University of Sydney, NSW,2006 The reaction of dry ice, CO 2 (s), with water or dilute sodium hydroxide solution has long been used to demonstrate the colours of universal indicator. The bubbling and clouds of condensing water vapour make it popular with students. By increasing the concentration of the sodium hydrox...

Jeff Hughes Royal Melbourne Institute of Technology The basis of modern Chaos theory is the search for underlying order in apparent randomness. The common idea of chaos is that of a system without any apparent pattern or order - out of control. This seems to imply that a system behaving this way has no underlying rules governing its behaviour. Ther...

G. Johnston University of Sydney Chemistry is making many contributions to our increased understanding of brain function. Simple chemicals serve as neurotransmitters mediating the transfer of information between nerve cells by activating chemically complex receptors. All nerve cells in the brain have receptors for the inhibitory neurotransmitter, G...

Richard T. Lowson Australian Nuclear Science and Technology Organization Brian J. Reedy and James K. Beattie University of Sydney Acid Mine Drainage (AMD) is a major environmental hazard for the mining industry. The magnitude of the hazard grows as the mining industry grows to meet modern material demand. The hazard arises due to the exposure of re...
