Today

Whoa... All this work on math and physics has left chemistry untouched..(especially this blog), and ms Jee is starting to take notice. (Surprised to recieved the email which I just read...hehe).

Okay okay, so my strengths and weaknesses eh? This is supposed to be personal but, oh well:

Strengths:
-Blast Furnace-From Fe2O3 + 3CO -> 2Fe + 3CO2

-Adding coke (carbon) to produce CO gas to reduce Fe2O3 into Fe (above)
C + O2 -> CO2
-Adding limestone (CaCO3) to remove impurities in haematite
CaCO3 -> CaO + CO2
In which CaO reacts with impurities (Silica/Sand) in haematite
CaO + SiO2 -> CaSiO3 + CO2
-And the 3 waste gasses are CO, CO2 and SO2

-Organic Chemistry (excluding macromolecules and polymerisation

4 common homologous series
-Alkanes, General Formula CnH2n+2, Functional Group C-C/C-H
eg. Butane=C4H10
-Alkenes, General Formula CnH2n, Functional Group C=C
eg. Propene=C3H6
-Alcohols, General Formula CnH2n+1OH, Functional Group -OH
eg. Ethanol=C2H5OH
-Carboxylic Acids, General Formula CnH2nO2, Functional Group -COOH
eg. Methanoic Acid=HCOOH

Hydration of alkenes form alcohols
Alcohols + Carboxylic acids = ester (a sweet smelling substsance used in perfumes)

Weaknesses: Atoms, moles and stoichiometry (Im getting better, don't worry...)
