I dropped physics. So tell me about chem and biology
Chemistry is a little bit easy compared to physics and biology. The syllabus requires you to learn the following
1-GENERAL CHEMISTRY . By the end of the topic you're supposed to know
-All atomic models
-electronic configuration plus quantum mechanics, etc
Hapo kuna mambo mengine mengi ambayo nimesahau kama marules ya heinsberg , hunds, de broglie, Einstein Equation, derivation ya bohr radius,mpaka schrodinger equation ili kuwepo ila ikatolewa baada ya watu kulalamika
-this topic can take up to 3 months
2-PHYSICAL CHEMISTRY . This is divided into 5 subtopics which are
-states of matter (harder )
-Electrochemistry (harder )
-Energetics (thermochemistry )-simple
- chemical equilibrium (simple )
-chemical kinetics (bit harder )
This topic can take up to 4 months
3-INORGANIC CHEMISTRY. This topic is divided into 2 subtopics
-GROUP CHEMISTRY . This part covers periodic table with its properties along and down the group such as ionization energy, atomic radius etc. Also you have to explain properties of each group from group 1 to 8
-TRANSITIONAL ELEMENTS - this covers all metals from atomic number 20 to 30 together with their properties like color formation, variable oxidation states etc.
-this topic can take up to 3 months
4-ORGANIC CHEMISTRY. Here I don't know how I can explain but in nutshell it has the following
-INTRODUCTION . Here you have many things to explain like bond formation and bond breaking(homo & hetero), nucleophile, electrophile, free radical. Inductive effects (-&+),etc
-After introduction, which is almost a topic on its own, you start the aliphatic, aromatic, carbonyl, amide, amine and many other compounds. Here all the properties learned in introduction are applied.
-Of all topics this is the hardest (many students like it but they can't pass ). it can take up to 5 months.
5- SOIL CHEMISTRY. This simple
6-ENVIRONMENTAL CHEMISTRY
It's very difficult to prepare a book which can contain all topics which is why each topic is presented in its own book. Physical chemistry alone can take not less than 250 pages (for a simplified book).
Because of its bulkiness the national advanced chemistry exam is divided into 3 papers. Two of them are based on theory while the third one is all about practicals
Lengo langu sio kuonyesha kwamba elimu ya kenya ni mbovu. Nataka kusema elimu ya bongo ina mambo mengi sana yanayomsumbua mwanafunzi. mfano mwanafunzi anayetaka kuwa daktari atasoma sana mechanics ya physics ambayo kiuhalisia hataitumia akienda kusoma Medicine.
