It assesses candidates' competence in science practical skills over an appropriate period of time that the candidates are offered the subject, [1] and constitutes 20% of the overall marks for the subject. SPA replaced the traditional Practical Examination, which was normally conducted at the end of the 2-year course, in 2006.
The bachelor's degree program in Computational Sciences [35] [36] leading to a Major in Computational Biology also starts with one year of basic studies in mathematics, physics and chemistry and courses in computer science. In the second year, mathematics and computer science are combined with the basic principles of molecular biology.
The Chemistry, Biology, Physics and Design Technology was last updated for first teaching in September 2014, with syllabus updates (including a decrease in the number of options), a new internal assessment component similar to that of the Group 5 (mathematics) explorations, and "a new concept-based approach" dubbed "the nature of science". A ...
The 2nd group of anions consist of Cl −, Br −, I −, NO − 3 and C 2 O 2− 4. The group reagent for Group 2 anion is concentrated sulfuric acid (H 2 SO 4). After addition of the acid, chlorides, bromides and iodides will form precipitates with silver nitrate. The precipitates are white, pale yellow, and yellow, respectively.
Spectroscopy is the related sub-discipline of physical chemistry which is specifically concerned with the interaction of electromagnetic radiation with matter. Another set of important questions in chemistry concerns what kind of reactions can happen spontaneously and which properties are possible for a given chemical mixture.
Importance: Influence, as described in the presentation speech for the Nobel Prize in Chemistry 1995: “The findings presented by this year's laureates in chemistry have had an enormous political and industrial impact. This was because they clearly identified unacceptable environmental hazards in a large, economically important sector.”

Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
