chemistry

Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant chemistry (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties of the soil on the moon (astrophysics), how medications work (pharmacology), and how to collect DNA evidence at a crime scene (forensics).
Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. There are four types of chemical bonds: covalent bonds, in which compounds share one or more electron(s); ionic bonds, in which a compound donates one or more electrons to another compound to produce ions (cations and anions); hydrogen bonds; and Van der Waals force bonds.

    Hivi mnaosoma kozi kama Bsc in Physics, Bsc in Chemistry, Bsc in Mathematics huwa mnapanga kuja kuwa kina nani hasa?🤣

    Hawa wasomi wanashangaza. Hivi ninyi ni walimu?🤣 Hivi taaluma yenu mnaijua kweli. Hivi inakuwaje mtu anaenda kusoma kozi chuoni ambayo hajui mwisho wa siku hajui atakuwa nani ? Au ni ilimradi tu "boom" lipo na kitaa wanakujua uko chuo🤣 Anyway, mimi sijui.

    Liangaliwe upya: Si rahisi kupata 'C' kwenye Chemistry kuweza kusoma Health-related programmes

    Jedwali limetoka, C ni 60-69 out of 100. Hizi ni alama za juu kidogo kwa A level chemistry. Hili lingeangaliwa upya maana wengi watakosa sifa hiyo. Kwa shule za private inaweza isiwe shida sana, lakini za Kata shida ipo (na si kosa lao, mazingira yao ya kusoma ni shida. Wataachwa nyuma)
