Key Questions Lesson 1 1. One argument against continuing research on the atom is that the cost continues to increase at an alarming rate‚ and the benefits seem to be declining. Whereas quantum chemistry experiments as early as 80 years ago were very cheap and yielded considerable practical results‚ now very few if any practical results are emerging‚ but the costs of experiments continues to increase. On the other hand a common argument for the continued

experimental techniques which can be used to tell us where the atoms are located in a molecule. Using advanced techniques‚ very complicated structures for proteins‚ enzymes‚ DNA‚ and RNA have been determined. Molecular geometry is associated with the chemistry of vision‚ smell and odors‚ taste‚ drug reactions and enzyme controlled reactions to name a few.

HL internal assessment IB websites may not always be the easiest to navigate‚ but they are generally comprehensive in coverage even if you have to dig deep to find what you are looking for and then combine available information. I think internal assessment in Business and Management tends to fall into that ‘dig deep and check for additional information’ category. Let’s examine where we should be looking for supporting material. Naturally we start with the programme guide. There are two essential

Extraction of Aluminium Aluminium ore is called bauxite. Bauxite contains aluminium oxide‚ water‚ iron oxide and other impurities. The purified dry ore‚ called alumina‚ is aluminium oxide (Al2O3). The alumina must be molten for electrolysis to work‚ since the ions are not free to move in the solid state. Unfortunately‚ alumina has a high melting point (2040 °C) and it is not practical to do electrolysis at such a high temperature. In the middle of the nineteenth century it was found that alumina

Incoterms 2010 – ICC rules for the use of domestic and international trade terms The Incoterms rules are a series of pre-defined commercial terms published by the International Chamber of Commerce (ICC) widely used in international commercial transactions. The Incoterms rules are intended primarily to clearly communicate the tasks‚ costs and risks associated with the transportation and delivery of goods. The Incoterms rules are accepted by governments‚ legal authorities and practitioners worldwide

contribute benefit to humankind. As time goes on‚ human has done many researches to ensure all these chemical substances will be enough for the use of themselves. 2 Chapter 9 of Form 4 syllabus introduces the students with manufactured substances in industry. This is important for the students to appreciate the knowledge of chemistry that is still new for themselves. Personally‚ I think that this chapter is an interesting chapter as it revealed the way of scientist produces the material around
