is joint author (with Ray Oliver) of Longman Chemistry for CXC (published Jan 2004). The second edition is called Longman Chemistry for CSEC. Both editions were adapted by Ray Oliver from my GCSE book. A retitled version of the book will also cover the new Edexcel Certificate in Chemistry which will be taught from September 2012. The two syllabuses will be identical from that point, with only tiny changes to the present International GCSE syllabus.

This book covers the Edexcel International GCSE Chemistry syllabus. It replaces Longman Chemistry for IGCSE co-authored by Jim Clark and Ray Oliver. I am the sole author of the new version, and the old book is not appropriate for the present syllabus. But it wasn’t only the outstanding students that we were successful with – there were plenty of ‘average’ students who achieved more than they ever expected.Occasionally a senior member of staff would show parents and potential students around the school, and they would be ushered into the lab with me in my pink lab coat, music playing, and everyone absorbed in the music and what they were doing. One parent told me later that it was this experience that decided them on sending their daughter to the school. Discusses the link between the physical properties of the oxides of the elements from sodium to chlorine and their structure and bonding.

The 21st century will see fundamental changes in chemical manufacturing and chemical use worldwide. Traditional petroleum resources will gradually be replaced by sustainable resources derived from nature including trees, plants and food and biorefinery wastes. Chemicals determined to be hazardous to the environment will have to be substituted. The unique set of circumstances provides an exciting opportunity for the discovery and application of new green chemistry solutions to these sustainability challenges. Each type of calculation is introduced in a very gentle way, making no great assumptions about your chemistry knowledge or maths ability. There are then lots of worked examples, gradually getting more difficult and showing as many variations on a calculation as possible. If you are working in another examination system, you still need to know exactly what is expected of you, but will have to find that information for yourself. A selection of questions that I have been asked lots of times about Chemguide together with a few general comments. There are also a number of chemistry questions that I have been asked and which I haven't been able to find good answers for!

Discusses the trends in first ionisation energy, atomic radius, electronegativity, conductivity, melting point and boiling point as you go across the period from sodium to argon. I have removed the Google search box because it was giving problems. Follow this link to find out how you can still search Chemguide using keywords. Covers basic atomic properties (electronic structures, ionisation energies, electron affinities, atomic and ionic radii, and the atomic hydrogen emission spectrum), bonding (including intermolecular bonding) and structures (ionic, molecular, giant covalent and metallic). Jim was a superb teacher of chemistry, a quiet authority in the classroom and laboratory, commanding respect from students and staff alike.

Potassium dichromate(VI) solution turns green as it reacts with the iron(II) ions, and there is no way you could possibly detect the color change when you have one drop of excess orange solution in a strongly colored green solution. With potassium dichromate(VI) solution you have to use a separate indicator, known as a redox indicator. These change color in the presence of an oxidizing agent. There are several such indicators - such as diphenylamine sulfonate. This gives a violet-blue color in the presence of excess potassium dichromate(VI) solution. The physical properties of the chlorides of the elements from sodium to sulphur, their structure and bonding, and their reactions with water.

Somewhere around the same time, I decided that I needed some music in the lab. Supervising class practical sessions needs total concentration so that you know everything that is going on in every corner of the lab, but if the practical is all running smoothly, this can get quite boring, particularly if what they are doing is rather routine. So, I spent some spare money on a tape player, amplifier and speakers and started playing classical music from my collection at home. urn:oclc:record:1357518972 Foldoutcount 0 Identifier calculationsinas0000clar Identifier-ark ark:/13960/s2b33239gvx Invoice 1652 Isbn 0582411270 Ocr tesseract 5.2.0-1-gc42a Ocr_detected_lang en Ocr_detected_lang_conf 1.0000 Ocr_detected_script Latin Ocr_detected_script_conf 1.0000 Ocr_module_version 0.0.18 Ocr_parameters -l eng Old_pallet IA-NS-2000803 Openlibrary_edition
