is a way toexplain molecular shapes that can't be explained easily by
considering simple overlap of the s and p orbitals. If only these simple atomic orbitals were
involved in bonding, all bond angleswould be the same as those between the p orbitals (all
90°). Hybridization is a mixing of valence atomic orbitals to give a new set of orbitals that reflect
the (correct) geometry of themolecule.
5 important uses or aplications of carbon:
1. The most important use of carbon other than food and wood is in the form of
hydrocarbons, most notably the fuil fossil methane gas and crudeoil petrolium.
2. Carbon when mixed with clays is used to make led for pencels.
3. Carbon is also used as a lubricant and a pigment, as a molding material in glass manufactures.
4. Plasticsare made from fossil hydrocarbons, and carbon fiber is made by pyrolysis of synthetic polyester fibers is used to reinforce plastics to produce lightweight composite materials.
5 . Carbon compundsmake up most of the materials used to make clothing, Such as natural and synthetic textile and leather, and almost all of the interior surfaces in the built invironment other than glass stone andmetal.
Medical or remedial uses of charcole
*Activated charcoal has often been used since ancient times to cure a variety of ailments including
poisoning. Its healing effects have been welldocumented since as early as 1550 B.C. by the
Egyptians. However, charcoal was almost forgotten until 15 years ago when it was rediscovered as a
wonderful oral agent to treat most overdoses and toxins.*can also absorb gas in the bowels and has been used for the treatment of gas or diarrhea.
*By adding water to the powder to make a paste, activated charcoal can be used as...
