At the O Levels, pupils have the option of either picking chemistry as a solo subject module– pure chemistry. They can still choose chemistry as part of combined science if they decide not to go with this path. In pure chemistry, you learn the subject by itself and ultimately discover more concepts, however in combined science, you study chemistry with one more science pillar for example, physics or biology.
Following your O Levels, you will again need to choose whether to take chemistry at junior college level, and if it is a H1 or H2 subject. If you are not confident in your science knowledge, JC chemistry tuition might just be what you need. If you wish to find out about everything chemistry has to offer and do not mind covering extra topics, pure chemistry might be best for you.
Who should choose chemistry
While some students find chemistry easy and do not see racking up well in it as a problem; however, there are many more who merely cannot seem to understand the basics of the subject no matter how much they work. There are a number of factors for this inconsistency that relate to the nature of the topic along with students’ separate approaches.
Unlike what some students might think, grading successfully in chemistry is not a hopeless undertaking. All you need to do is remember of a few important principles to remedy your bad habits and load the voids in your understanding.
Biotechnology (” biotech” for short) is an area of practiced biology that includes using living organisms and bioprocesses to develop or modify items for a details use. The growing of plants has been considered as the earliest instance of biotechnology and the forerunner to modern genetic engineering and cell and cells culture innovations. Virtually all biotechnology items are the outcome of organic chemistry.
Biotechnology is used in healthcare, crop production and agriculture, nonfood uses of plants and other products (e.g., eco-friendly plastics, vegetable oil, biofuels), and ecological applications.
Plastics and fibers
Fibers are substances that are continuous filaments or discrete elongated items, comparable to lengths of string. They are essential for a variety of applications, including holding cells jointly in both animals and plants. There are many different sort of fibers such as textile fiber, natural fibers, and human-made or artificial fibers such as cellulose, mineral, polymer, and microfibers.
Fibers can be spun into filaments, string, or rope; made use of as a component of composite product; or matted into sheets to make products such as paper. Fibers are frequently made use of in the manufacture of other substances. The toughest engineering materials are usually made as fibers, as an example, carbon fiber and ultra-high-molecular-weight polyethylene.
Synthetic fibers can often be produced inexpensively and in huge amounts as contrasted to all-natural fibers, however all-natural fibers have benefits some applications, especially for clothing.
