Too long never exercise my legs...starting to karat d..football skill from not good to no more.
seriously no football 'kaki' d
Just a little revision for some basic chemistry:
Formation of rust aka iron(III) oxide:
2Fe(s) + 2H2O(l) + O2(g) ==> 2Fe2+(aq) + 4OH-(aq)
Fe2+(aq) + 2OH-(aq) ==> Fe(OH)2(s)
Fe(OH)2(s) =O2=> Fe(OH)3(s)
Fe(OH)3(s) =dehydrates=> Fe2O3.nH2O(s) or rust
The chemical formula for rust is Fe2O3.nH2O; where n is vnumber of mole of H2O
(derived from http://www.chemicalformula.org/rust)
......
Seems like my brain karat d also. This doesn't sounds basic to me anymore but rather... 'ALIEN'
天啊！！
