PHYSICAL SCIENCE CORE experience: MATTER AND MATERIALS TOPIC: double-dyed(a) CHEMISTRY CLASS NOTES ____________________________________________________________ _____________ 1. ORGANIC MOLECULES entire chemistry is the of compounds of CARBON excluding CO2, CO, carbonates (CO3) and cyanides (CN-). at that place ar millions of these compounds and they range in size from simple molecules with 5 atoms to complex structures with thousands of atoms. Although the important particle is carbon, other elements much(prenominal) as hydrogen (H), oxygen(O), nitrogen(N), sulphur(S) and phosphorus(P) atomic number 18 as well common in these molecules. 2. SOURCES OF CARBON The principal(prenominal) source of carbon in organic compounds is carbon dioxide (CO2) in the air. Plants use sunlight to convert carbon dioxide into organic compounds by with(predicate) the process of photosynthesis. 6CO2 + 6H2O ? C6H12O6 + 6O2?H > 0 carbon copy is too found rude(a)ly in fossil fuels such as coal, oil and natural gas. essential compounds atomic number 18 important are important in our day-after-day life. They make up a large of each vivification organisms and are found in the food we eat. They are also used to make products such as the attire we wear, medicines, plastics, washing powders, dyes and many other items. 3.

extraordinary PROPERTIES OF CARBON degree centigrade has a fewer unique properties which are liable for its behaviour how it reacts and corpse bonds. Carbon has four valence electrons and they are all accessible for bonding. It forms sinewy covalent carbon-to-carbon bonds and allows long manacles to form. The chains freighter every be straight/un branched (fig. 2) or branched (fig. 3). This attribute is called catenation. Because of its position in the semiweekly table, carbon forms preponderantly covalent bonds with other compounds. The C C bonds are rigorously covalent (non-polar) because the deviation in the negativeness of the carbon (2.5 2.5) atoms is zero. The C H bond is also non-polar because the difference (2.5 2.1) is very low. The way come in of...If you want to get a full essay, order it on our website: Ordercustompaper.com
